I’m highly recommending Extension Architecture for their expertise to turn around a difficult planning application that I had refused from 2 other architects and they managed to get my additional new house at the end. A 3 year journey, but it was well worth it! I cannot appreciate enough their planning knowledge, and also now we are breaking ground. Their tender pack has saved me alot of hassle in choosing material inside the house myself. Especially their kitchen design has been great and cannot wait to see it realised. Thanks for all your input so far…
