John and the team did an outstanding job. It was easy to work with John and he was very knowledgeable, and provided very sensible advice. Other people quoted work which was over-the-top or wouldn't have solved the problem but John got right to the issue in a no-nonsense way. Quality of the work undertaken was very good, considering the age of the building and complexity. Would recommend.

Nicolae was great to work with, very accommodating, quick and unphased by bad weather. Did an excellent job with the blockwork at a good price and a good job with the plastering, which was little bit more expensive, but worth the assurance of having the same person do both jobs. Would recommend for similar, quick turnaround jobs.

Spencer at Pocock Developments project managed our work very well. From the fully detailed quote, to advising on any pricing changes and providing some extra plastering work - got to say everything was managed smoothly and transparently, and the one hiccup over the roof tiles was put right quickly. Plus we appreciated Myron and Ivan's eye for detail and managing their work around the weather. Our two dormers look great, so thanks Pocock Development and we'd definitely use them again ????
