Latest review:
We hired this builder for a 2-metre rear extension and a very large garage extension and we’re really happy with the result. The project needed a pile foundation which is a bit more complicated, but they handled everything very professionally. They listened to what we wanted and kept us informed at every stage, which really helped as we were living in the house while the work was being done. The team were friendly, easy to deal with and worked to a good standard. Overall a very good experience and we would happily recommend them.
