Loft Conversions West London

We know that space in West London is tight, especially in areas like Fulham, Chiswick, Hammersmith, Ealing, Putney and Richmond. Moving often means higher mortgage costs, stamp duty and disruption to schools and childcare, which is why so many homeowners now choose West London loft conversions instead of relocating.

A typical loft conversion can be completed on site in around 4 to 10 weeks depending on type and complexity, which is often faster and less disruptive than large ground-floor extensions. For families in Balham, Battersea, Clapham, Kensington and nearby areas, a well-planned loft conversion West London can add a new principal bedroom with ensuite, a pair of children’s rooms, a home office, or even a self-contained studio to increase rental potential.

Why Extend Up, Not Out

For many clients calling us about loft conversion SW London and loft conversion North West London, the core frustration is simple: there is no room to extend at ground level without losing the garden. A loft unlocks space that already exists within your roofline, which typically represents the most cost-effective square footage you can add to a London house.

Independent property data suggests that a quality loft conversion in London can increase overall property value significantly, often cited in the 15 to 25 per cent range when combined with good design and compliance. For investors in areas like Acton or Willesden, that uplift, combined with improved EPC ratings from better insulation and new glazing, can materially improve rental yields and resale options.

Key takeaways:

Converting your loft retains garden space and avoids the full costs of moving.
Loft conversions South West London and North West London often deliver strong value gains when professionally designed and signed off.

Typical Timelines & Disruption

Most of our loft conversions South West London and loft conversion North West London projects complete on site in roughly 8 to 10 weeks, which aligns with independent guidance that places complex dormer and hip‑to‑gable builds at the upper end of UK averages. The exact duration depends on specification, property condition and how quickly client-supplied items, such as bathroom suites, arrive.

In practical terms, the first week or two are focused on structural work above your existing ceilings, so internal disruption is limited mainly to noise overhead. The most intrusive day is usually when we open the ceiling for the new staircase, after which you can walk the shell with us to confirm layout before stud walls are built. Around 90 per cent of our clients remain living in the property throughout, which matches wider industry experience that lofts are among the easiest major projects to live through when well managed.

Our West London Loft Conversion Process

Homeowners often worry about planning rules in conservation areas across West London, from parts of Hammersmith and Fulham through to Kensington and Chelsea. We manage every regulatory step in-house, from measured survey and architectural drawings to planning applications and building control sign‑off, so you do not need to coordinate multiple consultants.

Design, Planning & Permissions

Our process for loft conversions South West London and loft conversion North West London starts with a free home survey where one of our specialists assesses roof structure, head height and stair options. We discuss your goals in detail, whether that is a quiet office for remote work, a master suite with walk‑in wardrobe, or a multi‑use family room that can evolve over time.

We then produce drawings, structural calculations and, where required, planning packages that reflect both your brief and local planning policy in boroughs such as Wandsworth, Lambeth, Hammersmith & Fulham and Brent. Industry experts note that it can take several weeks for councils to determine applications, which is why early planning is crucial to hitting your ideal build window. Throughout, we keep you updated with clear timelines and help you balance design ambition, permitted development allowances and budget.

Fixed Price Build & Weekly Inspections

Once plans are agreed, you receive a fixed‑price contract that sets out exactly what is included, so first‑time renovators are protected from vague estimates or hidden extras. External industry guidance stresses that clear scope definition is one of the best defences against cost escalation on residential projects, a view echoed by many independent building advice services.

During construction, we work with our own employed teams rather than unseen subcontractors, supported by daily site supervision and independent weekly inspections, which is consistent with best practice for quality management across the sector. Every loft conversion West London project carries our 10‑year warranty, backed by independent regulators, and sits under a minimum of £5 million public liability insurance, protecting you, your neighbours and your lender.

Start Your Loft Conversion Today

Many people researching loft conversion SW London or loft conversion North West London put enquiries off because they worry about cost overruns, unreliable builders or complex permissions. Independent consumer bodies frequently warn that choosing contractors without clear insurance, warranties or references is one of the biggest risks in residential building work. We respond directly to that concern with transparent fixed pricing, £5 million insurance coverage, a fully transferable 10‑year warranty and a strong track record of verified five‑star reviews on platforms such as Trustpilot and Google.

Local building service specialising in loft conversions and extensions across London, highlighting our bespoke design‑and‑build approach and long‑standing presence in the market. Industry commentators also note that loft projects which are properly documented, certified and warrantied tend to be easier to refinance or sell, because buyers and lenders gain confidence from clear paperwork and regulated inspections. Choosing experienced builders South West London and builders North West London who understand both structure and compliance is therefore an investment in peace of mind as much as in extra space.

Sustainable, Smart & Flexible Loft Design

Sustainability is now a priority for many London homeowners, and industry trend reports show rising demand for natural and low‑carbon materials such as sheep’s wool insulation, reclaimed timber and bamboo flooring in loft spaces. We design loft conversions South West London and North West London that prioritise high‑performance insulation, efficient glazing and optional solar‑ready roof layouts to improve comfort and reduce energy use.

Smart home integration has also become standard, with many clients specifying app‑controlled lighting, automated blinds, climate control and integrated audio to turn the loft into a connected, future‑proof floor of the house. For busy families, we often create flexible layouts where a home office doubles as a guest room, or a playroom can later convert into a teenager’s suite, matching wider design trends towards multi‑functional spaces in the capital.

Living At Home During Works

One of the main questions we hear from West London homeowners is whether they can stay in the property while works are underway. Across the UK, guidance suggests that loft conversions are frequently completed while the household remains in place because much of the structural work is carried out above the existing ceilings before the new staircase is formed.

Our staged approach mirrors this best practice, focusing early activity within the roof space accessed from scaffolding so disruption below is kept to a minimum. External experts highlight that clear communication and predictable working hours are central to a positive experience during any build, which is why we schedule regular on‑site meetings, keep dust control measures in place, and coordinate deliveries to fit around your family’s routine.

For West London Homeowners: Answers To Common Questions

How long will my loft conversion take? Across the UK, reputable data places the on‑site phase for typical lofts between roughly 4 and 10 weeks, with simpler roof‑light schemes at the lower end and complex mansards at the upper end. When you factor design and approvals into the overall programme, expert architects often suggest allowing several months from first concept to completion, which is consistent with how we plan projects to avoid rushed decisions.

Will it be very messy and disruptive? Independent guidance explains that the most disruptive period is often when the new staircase is installed and internal openings are formed, while much of the earlier work is contained within the roof structure itself. By planning dust protection, temporary protection to floors and carefully scheduled noisy works, we keep that intensive period as short as possible, typically a handful of key days within the overall build.

We used CCS for a loft conversion last year, adding 2 bedrooms and an ensuite, and would wholeheartedly recommend Dangis, Paul & team. We came into the project trying to be as cost effective as possible, and they came up with a suggested change that not only reduced our cost but one that we preferred to our original plans. Everything was completed to a high standard by the team and throughout the works themselves they were easy to deal with - good communication, responded promptly to anything that came up, and both were a regular presence on site. All in all a great experience and one that has absolutely transformed our living space!

Would highly recommend Clapham Construction for your loft conversion needs. Paul and Dangis were great to work with - responsive, considerate and happy to explain everything.They also had a great team behind them at every step of the process. Taking on a big project like this can be daunting but the team really made it stress free end to end. We are now really happy with the high quality finish achieved and the new space gained. Don’t hesitate taking your project forward with them!

CCS recently completed a loft conversion for us, adding 1.5 bedrooms and a shower room. The process was much smoother than we expected and all completed on the original timetable we agreed. Costs were also more transparent than similar businesses that we contacted for the job. Paul and Dangis dropped in most days and were hands on in managing the project. Their full team and all contractors they work with were friendly, professional and did a great job. They also gave us sensible advice on general roof improvements and fixing up part of an extension done by the previous owners. Would highly recommend them.

09:44 17 Mar 24

I cannot rate Paul and Dangis enough, heading up a strong team of highly skilled, professional and efficient tradespeople. The job was cost effective but finished to a very high standard. It looks amazing!Paul and Dangis from the start of the project to the end were super communicators, understanding and always present in assisting me to make decisions about my project ( a mansard loft conversion)Thank you team. I would have absolutely no reservations in recommending Clapham Construction Company!

Kate A.

13:03 16 Mar 24

Clapham Construction were total pleasure to work with when they did our loft extension at the end of last year. We’ve gained a beautiful shower room and an additional bedroom with support from the wonderful team at CCS. Paul and Dangis supported us to understand decision-making and choices at every step of the way. They managed all the (incredibly professional) contractors and any queries so easily that we felt completely supported but not overwhelmed. We would use them again for any future house project in a heartbeat.

CCS undertook a double single dormer loft extension and conversion for us in summer 2023 and we couldn’t be more pleased. Paul and Dangis were incredibly helpful from day one, assisting with the submission of the planning application, through to design solutions before and after start on site. The project was delivered on time, and the CCS team were very considerate - keeping the area tidy and even feeding our cat when we were away! Overall, it was a collaborative, open and stress free experience and we couldn’t recommend CCS highly enough. Marissa and Simon, Blackheath

One of the main reasons why I chose Paul and Dangis for my loft conversion project on a rented house in South London was the excellent reviews they had. Now, I am pleased to be adding a 5 star review myself as a happy customer. This was a daunting project for me, living abroad. There is a hell of a lot of detail involved and I had no experience on this size of a project. Paul and Dangis guided me through the whole thing really well from planning, party walls etc being really experienced specialists. The communication was crystal clear and they were always on top of the low level details which is no mean feat. When I changed my mind on a key project decision, requiring some structural work to be undone, they were flexible and fair about it. The finished job is high quality, was completed on time. and I am very happy with it. Importantly, they are very nice guys to work with, and my neighbours had no complaints about anything. I highly recommend Clapham Construction Services!

Sally S.

18:38 09 Oct 23

We couldn't recommend Paul and Dangis more, having had the worst experience with builders 2 years ago, we had the best experience with Clapham Construction. They were great at communicating timescales (and sticking to them) and everything was finished to a really high standard. They were really flexible to our ever changing decisions and very accommodating - suggesting ideas and ways to make things better. They really care and this makes the whole process pretty stress free.

Stephanie B.

09:09 01 Oct 23

We could not recommend Clapham Construction Service more highly. They recently completed our hip to gable with rear dormer loft extension in Streatham Hill. From start to finish, Paul and Dangis were fantastic. They did exactly what they said they would do, when they said they would do it - which is a rare thing thesedays. They guided us through a daunting process with great professionalism and good humour. They were regularly on site and always kept us updated about progress and next steps. They were always responsive and considerate. Their team of trusted workmen were highly competent and friendly. Their attention to detail was notable and much appreciated. We are very happy with the finished result.

Georgina K.

12:38 17 Sep 23

Really recommend these guys for anyone doing a loft conversion. They are really thorough and provide a lot of support throughout. The process is really quick too… it took 8 weeks for my loft and that was two bedrooms and one bath. There was constant communication and updates which was also really great! Huge thanks to the team for being approachable and reliable.

Elise R.

15:39 23 Aug 23

Cannot recommend Clapham Construction more! It was an absolute pleasure working with Paul, Dangis and their team as we built a mansard and did a loft conversion as well as adding an en-suite bathroom. The planning process was a really good opportunity to get onto the same page and their invaluable advice meant it all went smoothly with engaging neighbours and the council. The building works were done quickly and to a very high standard. While we went for relatively cheap options, I was impressed with the quality of the fittings and materials. I also appreciated that throughout the building process, there were constant quality checks by Dangis and also points where he gave some great suggestions on how to bring more light into the flat which has made a huge difference to the overall feel of our home. Sadly we are moving away from the area as our family is growing but I wish they CC could come to our new home and work their magic!

Our loft conversion took 9 weeks end to end and it was basically stress free (how many people have you met that say that about their building experience?!). Paul and Dangis were brilliant - knowledgable, empathetic and efficient. Would never use anyone else - highly recommend.

Helena P.

18:51 24 May 23

The fact that a building company has 100% 5* reviews tells you everything you need to know. They were brilliant. Efficient, Incredibly professional and responsive to all our questions. The thing that we found most impressive was the time that the guys took to clean up on a Friday to ensure there wasn’t that much dust and mess over the weekend. Would definitely use again.

Nicholas C.

12:11 12 Apr 23

Clapham Construction have done a great job on our loft conversion and we are very pleased with how smoothly the project went, and the brilliant loft space that we now have. Paul - thank you especially for guiding us through all the stages before and during the build. Their workmen were hard working from start to finish, efficient, and obviously very skilled. They were also polite, helpful and really tidy. We had great communication by email with their office, and with Paul in person and on the WhatsApp group - thank you. Our family in USA are now looking forward to staying with us in comfort this summer and beyond!

Bianca H.

08:00 16 Mar 23

Paul, Dangis and the team are simply top notch. They did such a high-quality job on a tight timeframe and communicated so well throughout. They were a pleasure to work with, handled all elements of the build from start to finish and kept disruption as minimal as they could. Couldn’t recommend them more highly if I tried.

Mindy L.

17:31 29 Jan 23

Thank you Clapham Construction! Your team were friendly, efficient, and highly motivated. The project ran to schedule with effective overlapping of tasks to allow for minimum disruption. Paul kept us actively involved at each stage of the process, so we always knew what was happening when, which was really reassuring. If we ever had a question, he would talk it through with us in person and offer advice without any pressure or expectation. The work is completed to an excellent standard. All the construction workers where kind, considerate, friendly, polite and kept our house as clean and tidy as possible. This took so much of the stress out of living on site during the works with a young son. Even the neighbours commented on how polite and considerate the builders had been. We would highly recommend this team for anyone thinking of undertaking a loft conversion in the future.

Laila A

13:01 29 Dec 22

Really lovely team - all professional, friendly and was great to have Dangis and Paul popping in regularly and being on the ball with the project. Happy with our new loft, all work done to an excellence standard, any follow up questions or issues dealt with quickly. Would highly recommend. Thank you very much.

Dani C.

07:51 25 Oct 22

Absolute professionals is the first thing that comes to mind when I think of Clapham Construction service. And there are two further things you need to know about them: they are brilliant at what they do and they are generous in spirit.Throughout our project Paul and Dangis answered our naive questions with warmth and care. They helped guide us at every turn, and almost certainly saved us money by making sure we considered all the options we had before making key decisions. But not just customer care, the building work is also top notch. The build itself was a well oiled process, coordinated with skill.I was initially worried about getting an anonymous loft company I'd never heard of in (after getting 8 different quotes from a variety of places including famous local ones) and being part of the 'box on the roof' brigade. Yet somehow, they have created build magic with some tweaks on 'a little bit of height' here, and 'a little configuration' there. We keep marvelling at the sturdiness and smoothness of the physical build even now, and the army of highly skilled teams they have were a pleasure to host in the house while we worked from home.And finally the most important bit - the money stuff- our Loft extension (including bathroom) was completed on time and more or less on budget. The additional costs were the unforseen - (yikes a victorian chimney needs dismantling!) and a few flourishes that we ourselves added to the mix - (can the door handles be gold?). Any additional build costs were communicated efficiently and immediately.Our experience of Clapham Construction is that they are patient, hugely knowledgable, and detail orientated with a wealth of incredible advice. Don't delay on getting them on your project!

Clapham Construction have done an excellent, high quality job on our loft conversion and I couldn't recommend them highly enough.They constructed an L-shaped Mansard with two bedrooms, bathroom and roof terrace. It was a very daunting project to go into but the process was seamless.We had around 5 different companies come in to give quotes and Clapham Construction was by far the best response in terms of information and presentation. Their pricing was competitive and in line with the others - a huge plus was how they set their prices from the start without changing. I believe the other companies fluctuate depending on the market prices at the time. One of the main things I liked about Clapham Construction is they do not take on too many projects so the owners (Dangis and Paul) give your project a lot of attention. At least one of them is on site most days and they are contactable via whatsapp. Be sure to ask about any possible extra work outside of the main quote so you can budget properly and not get any nasty surprises.Paul and Dangis were top experts and gave very good advice throughout. Their staff were very friendly and efficient. For the main construction/roofing/plastering, they completed this extremely quickly and I can't think of one day where there weren't loads of workers on site. The plumbing and electrics may take a bit longer but this is normal. Make sure you ask and find out exactly when you need to have tiles, bathroom items etc. on site because if you miss the deadline, it can hold up the work.Like with any loft conversion, you will need to be patient and communicate exactly what you want right down to the smallest detail, otherwise you may come to a misunderstanding during the project. Paul and Dangis were very good at adapting and carrying out my (probably unreasonable) requests.There was one incident where we had a gas leak in the front garden (nothing to do with Clapham Construction) and the scaffolding had to come down urgently so the gas engineers could dig down. I am sure this was hugely inconvenient for Paul and Dangis but they understood the emergency and the scaffolding was down within 48 hours at no extra cost. I'm sure a lot of other companies would not be so understanding.Overall we are so happy we went with Clapham Construction and we will be highly recommending them to any friends who want to do the same project.

We spoke to a few companies to quote our dormer loft conversion but were immediately impressed speaking to Dangis & Paul and went with Clapham CS. We’re really happy with the end result which has given us some much needed extra space. Progress was quick, these guys are very experienced and know exactly what they’re doing. They’ll talk you through your plans and give you honest advice at key stages when you need to make a decision, very patient with us too! Would definitely recommend, they’ve done numerous houses in our neighbouring streets too, end results always look great.

Highly recommend this company. As first time buyers and first time renovators we couldn't be happier with their service. Paul and Dangis are very professional and thorough, at no times does it feel like corners are cut. They are able to provide genuine advice and guidance while being accommodating ensuring a stress free process.

Clapham Construction completed our kitchen extension for us. We’re really pleased with the results, and it has changed the whole place. The price was agreed upfront and there were no hidden extras. Good communication throughout the whole process on WhatsApp and Dan showed great building experience. They had the whole team from build, kitchen fitting through to finishing the garden off available in house so made it a lot easier. Thanks guys.

We are delighted with our new loft conversion, Clapham Construction did a great job. They were highly professional, no hidden costs, and with friendly employees who treated the rest of the house with respect. We would not hesitate to recommend them.

There are so many horror stories of projects going wrong - thankfully ours was not one. Paul and Dangis run a very professional operation, communicate brilliantly and are upfront. The guys building were polite and respectful. The project was delivered on time, on budget and with no disputes or contestations. Could not speak more highly of CCS.

We had a loft conversion, new roof and windows.The experience from start to finish was a please. Paul and Dangis are very helpful even when I was asking for things that were not possible. The whole team is a crack squad - from roofers to plasterers and electricians. And all organised to slot in one after another. The end job is excellent. I couldn't recommend more.

I recently undertook a loft extension with Paul and Dangis of Clapham Construction Services and I cannot recommend them highly enough. From the first meeting through to completion, they were highly professional, responsive and provided a fantastic service. Throughout the project they offered sound advice and sensible solutions to my questions and wants for the project - it always felt highly personal and did not come across as just a ‘cookie cutter’ job. As a result I’m thrilled with the work and have no complaints in terms of how they managed and executed the project. They made what is often understood to be a highly stressful process feel like a breeze. I would recommend them to anyone

Knowledgeable, Detail oriented, Patient, and Amazing are the words that come to mind when I think of John Devlin and the Blue Ribbon team. I approached John expressing my interest to have my unfinished basement space turned into a ManCave. I dragged my feet for over a year and the whole time John was patient, shared ideas with me, but never rushed me, and as soon as I was ready… he rolled me into their very well organized development process. It is clear that NOTHING is left to chance and that the project will be PERFECT due to all the planning and detail that is done UP FRONT!!!!

CCS recently completed a loft, bathroom and kitchen renovation on our South London Terrace. Start to finish the service and end product were excellent, specifically:-Initial quotation - Dan/Paul worked with us to understand what we wanted, work through challenges and refine our ideas. Compared to other contractors we felt they listened, and provided a quote that whilst not the cheapest was a fixed price with clear indication of costs for extras.-Design- The wider team guided us through Building Control process well, refining the design as needed to make all appropriate submissions to the local council/supporting Party Wall requirements as necessary.-Build/Finish - Great team, always professional, efficient and punctual. Quality of finish was excellent, managed COVID supply chain issues well.-Recommendation - Highly recommended. This type of project is daunting especially if like us you haven't done this before. If you're considering one of your own, i'd strongly recommending calling CCS.

I couldn't be more pleased with the job Clapham Construction did on my loft conversion and rear extension.The work was completed so quickly to a very high standard. Paul and Dangis were great with communication throughout and helped resolved any potential issues with building control and surrounding the party wall award.I wouldn't hesitate to use them again and would definitely recommend their services!

Our experience with this company was excellent from the initial consultation, through the building work on the rear dormer, to the final touches inside. The major structural work happened gratifyingly quickly (considering it was February), while the later internal work took a little longer. However it all worked out well and Paul and Dangis provided us with support throughout. Overall a really good experience for us, and really happy we went ahead with these guys.

Paul and Dangis are everything you want from your builders from the very get go. Approachable, honest, flexible, professional and most importantly, experts at what they do. We replaced our 1 room loft extension with a full hip to gable conversion and now have 3 wonderful rooms with so much more space. They listened to our needs, advised what they thought was best, and were always willing to tweak where required. We are exceptionally happy with the end result, and would welcome Paul and his team back any time for any future building works.

Clapham Construction did a loft conversion for us and we’re really pleased with the end result. The process began with a really detailed chat with Paul about what we wanted and what was realistic for the space. The quote offered good value and having talked to neighbours who’d used the company we were happy to go with them.The staff were quick and efficient and Paul and Dan kept in touch and visited frequently throughout to keep on top of the job and keep us in the loop.Payments were split by stage, which is great as you can control your budget and know what’s been delivered and when. The final payment is only made once snagging is complete - this was great as we’ve had experience in the past of builders never finishing jobs off. Not the case here!Overall really pleased, would use them again and very happy to recommend!

I'll confess I am a bit picky when it comes to renovation work, dad was a builder. I ended up getting 10 or so quotes for the works, it we were a little caution from the passed. Dan and Paul came and spent the longest time with us just discussing our needs and planned use... we really appreciated this as no one else asked. There advise was then based completely on that, talking us out of some additional works that they felt wasn't needed... which we really appreciated.There quote was mid-range compared to others, but unlike most was fully inclusive and jargon free.We took the plunge feeling the most confident with them and so so happy we did. In short, they delivered on what they said, what we wanted and how they said they would. Admittedly this wasn't;t in the way we imagined, but once they explained it, this made sense. Working in a law practice setting expectations is key.Lovely chaps, great value and a fixed budget, excluding some add ones we opted for.Thanks for everything and looking forward to planning a rear extension with you

I was considering making an offer on a property with an old, poor quality loft conversion which we were looking to update after purchase. Paul @ Clapham Construction was able to give me great advice and expertise on my options, and his honest advice was extremely valuable and ultimately saved us £££ and hassle up front.Once we have identified a loft conversion project in the near future, Paul will be the first person I call. Thanks.

The first thing you get with Clapham Construction is a First-Class service.Paul and Dangis gave us a really personal, tailored service, which meant so much to us when undertaking our first loft conversion.Right from the off Paul went out of his way to offer his expert consultancy, helped us to make key design decisions and saved us thousands!!!Clapham Construction offer a level of professionalism higher than a number of their competitors, from working with us, the quoting process, to scheduling the works, implementing the build and their after-service care... definitely value for money.Even after the project has been completed, we are still in contact (via our project WhatsApp group), share a joke or two and let the guys know if we have any problems.Well done guys and continue the good service!

After a lot of research into local firms for our construction work Clapham Construction Service came out on top. From quoting to completion they were a very helpful and hands on team - if there were any issues (not their fault!) they solved them quickly - would highly recommend! They demolished and refitted our bathroom & kitchen - and we are about to use them again for a mansard rood extension.

Clapham Construction were extremely helpful and responsive throughout the build and the results were fantastic. The vaulted ceiling looks very dramatic and the loft feels spacious and light.

Great team a pleasure to work with. Paul and dangis are very responsive and resolve any queries very quickly which is a nice change when compared to previous builders we have used. So wouldn't hesitate to recommend Clapham construction

Everything was very easy from start to finish with these guys. Terms agreed up front with nothing hidden at all, communication brilliant the whole way even with a Whatsapp group with questions answered 7 days a week! The finish is of an incredibly high standard and advice & direction given when necessary was great. Couldn't recommend these guys enough and would most certainly use again if I ever required.

19:03 16 Apr 20

The team are brilliant and a special thank you to Dangis and Paul. They are hands on. We had an existing loft, which was done by the previous owners 20 years ago and it was awful. These guys came, provided a really competitive quote.....which I advise everyone to check against others... Clapham construction initially looked a little more expensive than another quote, but when you look into the detail they include everything we needed and there were no extras... another company would have charged for every addition which would have come out more expensive in the end... which is a bit naughty really. Very impressed with the speed and communication was really hot... Dangis/Paul were around all the time and as owners sorted everything for us.... exactly what you want really. Thanks Gents

I was initially going to leave a glowing and Positive 5-STAR review, but to be honest I will use this opportunity to say THANK YOU!!! again to Clapham Construction. Paul and Dangis have been exceptional. We starting our loft conversion 3months ago and where nearing completion when this whole Covid-19 thing hit and we were seriously worried. These guys knew we had some medical concerns in the house and they were nothing but brilliant. They had us watertight and completed as well as maintaining really decent levels of social distancing throughout.. now we have a dream loft and they have been terrific at helping us source materials for completion considering the circumstances... carpets, paint etc... even let us hire some of their team for moving furniture etc.. upstairs to complete.... Thank you, Thank you.... anytime you guys need anything just let us know... as I said we owe you big time.... Cathy xxx

From the moment we met Paul and Dangis we knew we were on to a winner! They compliment each other really well and they made us feel so at ease from the word go. Nothing has been too much trouble and their communication is unreal - they always get back to us and no matter how many times we called / text - they always had patience and a sense of humour ! But above all - we love our house! We had a loft and an extension and both have been incredibly done and on time ( if not quicker than planned) . The quality and finish is brilliant , all of the tradesman that they have working for them are excellent. We were terrified of entering into this process as we have heard such horror stories but their business is run so well that we have never had to worry ! I highly highly recommend these guys if you planning on doing a build ! Thanks guys !

Super Happy with these guys. Previously we hand some large 'all London brand' doing all our works. But really we were not happy as the works is passed over to guys on site and no one oversees it.... so you pay for nothing really. So we looked for someone more reliable. We found clapham Construction by recommendation and we were not disappointed. Start to finish they did what we agreed and delivered what they promised.... we are not the most trusting of people but we couldn't ask more of Paul and Dangis and all their teams. As for the Loft Conversion.... It's amazing.

Reviews are often subjective, just look at Trip advisor, I guess you can't always be satisfied with circumstances and services all the time, especially in your home. What I love about these guys in on day one and particularly in the pre-construction meeting, they sat me and my wife down and told what to expect (the worst bits), what could go wrong and what they would do about it. A bingo, they did just that, including a small leak we had through the skylight. Brilliant reaction and responsibility. Overall the service was very good, they were clean, tidy and respectful, laying sheets from the front door to the back so they could move materials without making a mess. Top job.Special thank you for Paul and Guy

I am extremely happy with the services of Clapham construction and the outcome of the completed loft conversion. The workmen were tidy, polite and completed on the job instructions. I would highly recommend to all who dream of having a dream come true loft! Special thanks to owners/project managers Paul and Dangis, they been on site nearly every single day to check progress and keep me up to date. They did exactly what they were contracted to do and that’s why we Love them!!!

I found Clapham construction service on Youtube, when I was browsing, trying to educate myself on the process of a loft conversion. I was seduced by some lovely videos to be honest but invited them to quote for the works. To be honest without sounding so enthralled like some other reviews I’ve read… they did and acted exactly as they represented on the videos and website. I couldn’t complain about anything because they did exactly what they said on the tin. Having spoke to the owner a few times it seems they limit the number of jobs they do per year to ensure they the management can personally manage each job, that’s a good business model.

I have already recommended these guys a few times already. I do property developments so these guys have done some refurbishment, extension and lofts for me. They are brilliant. Saved me money and time (compared to previous contractors). They were onsite everyday checking the quality, progress and dealing with issue... so i did not have to get involved. Well worth calling them
