$$$$ Home Builders & Construction Companies in Radlett. 4 Stars And Up

“Homeconcepts completed a substantial rear and side return extension on our home in Fulham earlier this year. It was a complex build. Space was limited and there was a fair amount of planning permission and structural engineering to work through before anything could start. The site team, the project management and the quality of the finished work were outstanding throughout. Every detail has been carried out to a very high standard. We're genuinely pleased to hear that friends nearby are now bringing them in for their own renovation next year. We wouldn't consider using anyone else for future work. Couldn't be happier with the result.”

“James and his team built a two-storey side extension to our 1930s home. We spent a lot of time researching local builders and we are so pleased we found JMB Design & Build. However busy he is, James is always contactable and responsive and he has a keen eye for detail. James worked to our budget for which we are very grateful. During the build we were able to add a room in the newly created loft space which has been a huge bonus and James was great at finding creative solutions to make it work. The end result is a lovely family home that has retained its original features but it now fit for modern life. I would recommend James and his team highly. You can see the project on the JMB website.”

“I recently had RAS Construction carry out a full renovation of the entire downstairs of my home, including transforming the living room, hallway, downstairs toilet, and creating a completely open-plan kitchen and living space—and I honestly couldn’t be happier with how everything turned out. From the very first conversation, they made me feel completely at ease. Taking on such a big project felt quite daunting at first, but their professionalism and clear communication really helped settle any worries I had. They took the time to listen to what I wanted, offered helpful suggestions, and made sure I felt confident in every decision along the way. What really stood out to me was their attitude throughout the whole process. Nothing was ever too much trouble—no matter how big or small the request, they were always happy to help and find a solution. It genuinely felt like they cared about getting everything just right, not just finishing the job. The quality of the work is absolutely superb. Every part of the renovation has been completed to such a high standard, and you can really see the attention to detail in every room. The open-plan space they created has completely changed how we use our home—it feels brighter, bigger, and much more suited to everyday living. On top of that, they were a pleasure to have around. The whole team were friendly, respectful, and incredibly tidy. They kept disruption to a minimum and always made sure things were left as clean and organised as possible at the end of each day, which made a huge difference while living through the renovation. Overall, I’m so grateful for the work they’ve done. It’s completely transformed our home, and I wouldn’t hesitate to recommend RAS Construction to anyone looking for a reliable, skilled, and genuinely hardworking team.”
