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 New Malden, 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).

Planning and building regulations in New Malden
The approval route for New Malden is set by planning law in 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.
