Don't take our word for it. Here's what they have to say about Better Homes Studio.
Better Homes did a fantastic job carrying out a complete renovation of our 1930s ‘chalet bungalow’ in Chingford. Many thanks to the project managers - Gino, Celli and Elena - and to their entire team of craft workers
Jack Robertson@jack_robJI couldn't recommend Celino and his team more highly. They were extremely professional, hardworking and have great attention to detail.
Hunter@hunter_uHI had our kitchen redone and couldn’t be happier! Celino’s team were amazing from start to finish. They worked so incredibly hard to get everything completed within time and at a high standard

Don't take our word for it. Here's what they have to say about Better Homes.
I could not recommend them more highly. The whole process was so streamlined and efficient. They submitted a very detailed quote which was competitively priced, and went onto do the work very quickly to a high standard.
LI couldn’t be happier with my kitchen and bathroom renovation. The better homes studio managed to bring my vision to life, I still can’t believe it is the same house...
MThe quality of workmanship is extremely high and they have managed to translate loose ideas out together on PowerPoint by me into reality.
S
We have now worked with Celli, Gino and the team twice, once for a major renovation and once for some minor but important work, and both times we have been absolutely delighted with the service that they have provided.
HThe team holds themselves to high standards, and we couldn't be happier with the top-notch quality of the end result.
KAfter checking out loads of loft conversion companies in North East London, we finally decided to go with Better Homes Studio for our hip to gable loft conversion. Just a couple of months after our first chat with Gino, we've got an amazing loft conversion, all done and dusted in just 9 weeks, just like they promised from the get-go.
