Covering Walton-on-Thames

Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
What is architectural design and planning?
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.
- Measured survey of the existing house
- Design options and 3D views
- Submission and liaison with the planning officer
How much does architectural design and planning cost in Walton-on-Thames?
Typical ranges for architectural design and planning. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

|---|---|
| Measured survey and existing drawings | £500 to £1,200 |

What approvals does architectural design and planning need in England?
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 I think about before starting?
- Planning and building regulations are separate approvals; most projects need building regulations even when planning is not needed.
- Conservation areas and listed buildings need extra design care and supporting statements.
What happens after I enquire?
- 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.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
