Covering Carshalton
We work in Carshalton (SM5) and the places around it, including Sutton, Mitcham and Morden.
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 do you get with 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.
- Planning or lawful development certificate drawings
- Submission and liaison with the planning officer
- Structural engineer’s calculations

How is architectural design and planning approved in Carshalton?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
We confirm whether your project is permitted development, needs prior approval or needs a householder application, and prepare the right submission.
What should Carshalton homeowners check first?
- Pre-application advice from the council can help on sensitive sites.
- Conservation areas and listed buildings need extra design care and supporting statements.
From first call to completion
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
