Homes in London

Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.

What goes into architectural design and planning?

Designing and building under one roof means the drawings are priced as they are drawn, so there are fewer surprises when the quote arrives. If you only need drawings and a planning application, we can do that and you are free to use any builder.

How is architectural design and planning approved in Purley?

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

We confirm whether your project is permitted development, needs prior approval or needs a householder application, and prepare the right submission. A lawful development certificate is the best proof that permitted development work is lawful.

What can affect architectural design and planning?

Planning and building regulations are separate approvals; most projects need building regulations even when planning is not needed.
Pre-application advice from the council can help on sensitive sites.
