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.

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.

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!

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!
