What are the Best Loft Conversion Types for Wandsworth Homes?

Wandsworth’s beautiful Victorian and Edwardian homes are ideal for several types of loft conversions. We recommend the best solution for your property type and needs.

  • Dormer Loft Conversion: The most popular choice, a dormer is a structural extension that projects vertically from the roof, creating a box shape that adds generous headroom and is perfect for a new bedroom and en-suite.
  • Hip-to-Gable Loft Conversion: An excellent solution for semi-detached or end-of-terrace homes. This conversion extends the sloping ‘hip’ roof at the side of your property into a vertical ‘gable’ wall to maximise the internal area.
  • Mansard Loft Conversion: Often built to the rear of the property, a mansard conversion alters the roof structure to create a flat roof with a back wall that slopes inwards at 72 degrees, maximising available space.

Testimonials

Case Study: Dormer Loft Conversion in Knoll Rd, Wandsworth SW18

On Knoll Road, we transformed a loft in a terraced house into a large, bright bedroom with a spacious en-suite. The project featured a large dormer window and a Juliette balcony. The entire conversion was completed in 10 weeks, providing the client with a high-quality, fresh, and bright new living space.

“Clapham Construction designed, planned and carried out our upstairs double dormer extension towards the end of 2019 and we can easily say it's been THE least stressful build we've done so far. It's also been the biggest piece of work we've had done in our house which hopefully tells you something about how well organised everything was!

Paul and Dangis were in contact daily and on site several times a week, checking that everything was going to plan. The work was carried out to schedule with great communication and using highly self-sufficient tradesmen. You certainly won't be popping the kettle on every 5 minutes as they crack on and power through the day, making amazing progress by the end of each week.

Paul and Dangis knew we were on a tight budget and did everything they could (including the purchase and delivery of tiles to us at wholesale price) to help us stick to our budget. We now have an upstairs shower room which is an absolute godsend and our son has a much larger bedroom he can grow with for many years to come.

Thanks so much to all the team for such a stress-free (and dare we say enjoyable?!) experience. We'd love to have you back again for future projects and would recommend you to everyone."

From the initial meeting to the final finishing touch, Paul, Dangis and their team were great! We knew exactly what to expect each week, we had lots of photos and drone videos of work happening when we couldn’t see. They were full of advice and suggestions when we couldn’t visualise the end result. They left our home as clean and as tidy as they possibly could (we were living in the house as they were working around us). We are really pleased with the end result and with the building experience! Great time, fantastic work ethic and brilliant result!

We can’t thank Paul, Dangis, and the team, enough for their hard work on our house. The house is everything we had imagined and more. We increased our scope multiple times throughout the process, and the team helped us seamlessly, and were always there to answer questions and support our plans. We only have good things to say about Clapham Construction, and will definitely be recommending them to all our friends and family. Thanks again!

I cannot speak highly enough of Clapham Construction. Paul and Dangis were a dream to work with from start to finish. Everything was communicated so well and they provided honest, transparent and clear advice throughout; I felt supported and guided through all the decisions and they helped me make more bespoke decisions such as our windows and floor which weren’t necessarily easy! Everyone who came to work on the loft was excellent and it has all been completed to a high standard. The loft is beautiful and we just can’t believe how much space we have and how well done everything is. I would (and have!) recommend to anyone! Thank you Paul and Dangis - and we will be coming straight back to you for the next project!

We’ve had our dormer loft conversion for coming up to three years now and haven’t had any major issues in this time. Any minor snagging issues have been dealt with quickly by Clapham. The whole process from start to finish was seamless. All the builders were very friendly and considerate too. Will continue to recommend this company to anyone who needs a loft done and will not hesitate to use again in the future. Thank you!

Clapham construction service was extremely professional, the project was finished before the plan and we are so happy with our new space. Problems were resolved quickly and efficiently throughout the process. This was one of our best investment that not only added value to our property but also a significant improve of our quality of life.

I had a loft conversion completed by Clapham Construction Service earlier this year and couldn't be happier with the results. Paul and Dangis were on site every day and kept me fully informed throughout the entire process. Their communication, professionalism, and attention to detail were outstanding. I felt completely confident in their work from start to finish. Highly recommended for anyone looking for reliable and high-quality building services.

We recently completed a double mansard loft conversion with Clapham Construction Service, and were very happy with the whole design and build process from start to finish. Paul and Dangis were great to work with, providing clear communication and always being available to answer questions or discuss options. Their team are also excellent, with all the trades doing a great job, very professional and respectful of the rest of our house. Inevitably with a build project there were a couple of issues that cropped up along the way, but CCS were excellent at helping resolve them. We are delighted with the final loft and the extra space, and have already recommended them to others!

We have just completed a loft conversion with Clapham Construction and it was great! We are so pleased with the new loft we have in our house, but the process of working with CC was really good. They were easy to engage with from the outset, the price was competitive and the actual construction was quick and efficient. Obviously it was a major building project with all the mess and decisions you’d expect, but it was made a lot easier and less stressful working with Paul, Dangis and the team. They completed the project on time and on budget and we enjoyed working with them - that is more than almost anyone we know can say about similar projects! We’d definitely recommend them.

We had an exceptional experience with Clapham Construction for our loft conversion. Paul, Dangis, and the whole team were fantastic from start to finish. They transformed our attic into two beautiful loft rooms and a bathroom, exceeding our expectations with their attention to detail. The entire project was completed at an impressive speed without compromising quality. The team showed great care throughout, ensuring everything was done to the highest standard. Their service was professional, friendly, and stress-free. We’re absolutely thrilled with the results and would highly recommend Clapham Construction!

We have recently used Clapham Construction Services for loft conversion to add a bedroom and a bath in the house. We are very happy with the end-to-end experience with Paul, Dangis and the entire CCS team for high quality work done in quick time and with a very collaborative approach. Our overall project went into some unexpected blockers, but Paul and Dangis patiently helped us to resolve all the matters, kept us updated with timely communication and have been very flexible to guide us. They brought in a fantastic team to complete the work fast and in a cost-efficient manner. We will recommend CCS any day as a trusted team for home transformation projects.
