Extension Architecture is a group of planning consultants and architects. Many architectural practices in London are expert in one specialism or the other, but with us you can have both under one roof. When you book us as your residential architect, you can save time and money, obtain planning consent with your first application and optimise the value of your property.

Contact us for help with council planning for your extension, loft, garage conversion or basement. Our vast experience as one of the top architecture firms in London means our approval rate with the London council planning departments is very high. We can also make your planning application for a change of use or even a new builds, where we love to use natural materials in the design. Our team are skilled in 3D video renders and interior design, so our portfolios now include interior schemes and corporate identity for several restaurants and retail brands.

We believe some of our more beautiful designs have had an impact on London architecture, and we find this a dynamic and exciting field to interact with. Client satisfaction is our focus, so we continue our collaboration until all the Ts are crossed and the Is are dotted. We work with home-buyers who may have little knowledge of the planning route, as well as developers who are well-versed in the process.

Architects’ Services in London – Our Process

Any work under London Councils, we would undertake a property site assessment by looking into its history and context of the site with its surroundings. In the process of design we aim to be up to date with all the regulations, taking into consideration the conservation and heritage sites and we approach it with a sympathetic proposal to consider the characteristic surroundings.

The rules and regulations for planning application and building regulation vary from council to council. We always keep ourselves aware of the changes in the Borough. Additionally, we would take time to study the reasons as to why the other properties get approved and refused within the area helping us to better our understanding and maintain a good success rate. Our in house experienced team are always there to help you.
