Couldn't be happier with my side infill extension!
Newspace set us up with a kitchen in our large living room so that we didn't have to move out while the work was being done - they even had a working dishwasher for us! The workmen were polite, unobtrusive, tidy and extremely hardworking. Vitali, our project manager, was on the ball the whole time and the project went smoothly and according to our plans. Would definitely employ this company again for further work on our home.

We employed Newspace to build our loft conversion and we could not have been happier with our decision. Amazing attention to detail throughout the entire project, superbly project managed by Vitali and Graham and the quality of the work really was first class. The builders were efficient and completely unintrusive, and all the tradesmen they used were incredibly skilled as well as being friendly and polite.

Disappointed as we never got past the quote stage. Seemed like a capable company that we would have probably used for our full house refurbishment. However, after they visited the property and seemed enthusiastic to do the work, we heard very little from them and received no quote. After chasing them, we were told that they were very busy - which they could have communicated much earlier.
