Homes in London

Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.

What does architectural design and planning involve?

Architectural design and planning covers everything before building starts: a measured survey of the house, design options, planning or permitted development drawings, the application itself, building regulations drawings and structural calculations. We offer it on its own or as part of a design-and-build project.

Planning and building rules in Finchley

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 should Finchley homeowners check first?

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.

What are the steps?

Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
