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…
Delighted with the application approval that we got yesterday. As discussed initially, we were dubious of our chances as our property in Weybridge sits in a flood risk area + conservation area. But our full application for the 4m extension to the rear have been approved without any hassle. Also Elmbridge council was able to give us the approval within 7 weeks, so an added bonus. Thanks Especially to Youno who was very helpful in outlining all the pitfalls and guiding us to this position.
Thank you for your efficient service. Really impressed with the level of service and the speed!
Working with Nadir at Extension Architecture was a truly trouble-free experience. They explained the process and was always at hand whenever I had questions. I trusted their judgement whenever they provided amendments to my initial plan and was thoroughly happy with the end result! 11/10
