ASH BUILD
House Extension Professionals in London
Average rating: 5 out of 5 stars22 February 2019
“Ash Builders refurbished my house in June 2018. From start to finish I received the most excellent service. Slim’s knowledge of the building trade and refurbishments was extremely insightful, helping me make good decisions on what I could have in my home. The work was carried out by Slim and his sons in the time frame arranged and was done efficiently with minimum disruption. A hard task when internal walls were being knocked down. They were clean, tidy and friendly. No job was too big or small for them, even when I changed my mind! I would 100% recommend Ash Builders for their above excellent work. My home is everything I wanted it to be and more.”

MoreSpace
House Extension Professionals in London
Average rating: 5 out of 5 stars29 January 2021
“We decided to choose MoreSpace to build our loft extension and were so glad we did. We were firstly consulted by Stuart Ellerby who gave us a thorough overview of what was involved in a loft extension and who is responsible for what during the project. His knowledge was first class and he spoke in layman’s terms and not jargon which we found very engaging and brought it to life. Once we agreed on the project, Stuart also kept in touch throughout with regular site visits and was also super responsive when we raised any questions. His aftercare has also been great. The team who built our loft was insane. The team was led by Jake and everyone in his team were super friendly and accommodating, whether it was popping up for a sneak peek on progress, asking any questions or looking to make slight adjustments. The finish of the job is perfect and exactly what we’d hoped for. They left the place clean and was complete within a much shorter time period than I expected. For such a large project, this felt like the easiest one I’ve had to undertake so far thanks to Stuart, Jake and his team. We did shop around with 4 other competitors and these by far have the best reputation and I’m glad I trusted the reviews. 5* Thanks Team!!!”
