What is a set of architectural drawings?
Architectural design turns your ideas into drawings that a council and a builder can work from. It starts with a measured survey of the house, then design options, planning drawings and, once approved, detailed building regulations drawings and specifications.

In Carshalton, a set of architectural drawings typically costs £2,000–£5,750 for planning and building regulations drawings for a typical extension, including VAT at 20% (standard rate). Prices across London are typically 30% above the UK average for this kind of work, which is reflected in the range for Carshalton. Council application fees are extra.

Planning and building regulations in Carshalton
Approvals for a set of architectural drawings in Carshalton follow the rules for England. In England drawings are prepared to suit the local planning authority’s validation list and, later, building control.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
Handled as part of most architectural drawings:
- Tender-ready drawing pack
- Design options and sketch layouts
- Measured survey of the existing house
- Structural calculations coordinated
- Party wall drawings where needed

How long does it take?
Allow 2 to 6 weeks for drawings, depending on complexity. If the drawings are for a planning application, add the council’s decision period once they are submitted.
