In the heart of Balham, Clapham Construction brings a fresh perspective to loft conversions. We recognise that Balham, steeped in history and bustling with modern charm, isn’t just a place—it’s a lifestyle. Our design ethos mirrors this, capturing the elegance of landmarks like the Victorian-era Balham Station or the Art Deco Du Cane Court, and integrating it into our loft conversions. We aim to create spaces that respect history, relish the present, and look towards the future, much like Balham itself. As your neighbours, we strive to ensure your loft conversion complements both your needs and Balham’s unique character.

Loft conversions in London are one of the most popular methods of home renovation for the simple fact that they require no extra floor space and they make use of what is essentially dead space you already have in your home. 

Add to this the fact that they can add on a fantastic amount of value to your home and it’s clear to see why so many choose to extend their home with the help of a loft conversion.

From additional loft bedrooms with ensuites to loft games rooms and more, a loft conversion can be put to so much use and what’s more there are so many different ways to do them too.

With the help of our incredible team here at Clapham Construction, we can help you achieve the loft conversion of your dreams.

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!

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.

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.

Paul, Dangis and their team were excellent given we had some obstacles with the council on design, they accommodated what we required. The work was very professional and communication was on point. We are very happy with our end result and any teething issues they resolved quickl. I would recommend the team to anyone. Thanks again for all your hard work.

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!

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.
