Wallington
Rear ExtensionWe were unaware about additional details needed for our loft, things like proper structural drawings & obscure-glazed windows & that got us into unexpected expenses. But luckily we got referred to EA & they did a fantastic job with our bedroom with en-suite inside the newly developed loft, which is a lot more than I would’ve thought. The final space is beautiful, practical, & totally worth it!

Double-Storey ExtensionDelighted 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.

Kitchen ExtensionI’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…
