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.
How much does a set of architectural drawings cost in Keynsham?
In Keynsham, a set of architectural drawings typically costs £1,500–£4,500 for planning and building regulations drawings for a typical extension, including VAT at 20% (standard rate). Prices in the South West sit near the national average for this kind of work, and the range for Keynsham reflects that. Council application fees are extra.

|---|---|

The main things that change the cost:

A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Planning and building regulations in Keynsham
Approvals for a set of architectural drawings in Keynsham 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.
