Planning Applications and Permissions in Southwark





Planning Applications and Architects in southwark – Planning Consultants

Extension Architecture is an experienced team of planning consultants and Architectural designers. They are here to provide friendly and helpful services assisting you from initial design ideas through to planning, building control and into a reality. Our success rate is nearly 100% from house and basement extensions, loft and garage conversions, change of use applications, new builds and commercial planning.

Any work under Southwark Council, 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 Southwark 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.
