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 Bromley, 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 Bromley
The approval route for Bromley 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.
We check this for your address before design work starts, so there are no surprises later.
What we handle
From survey to sign-off, the job normally involves:
- Design options and sketch layouts
- Building regulations drawings and specification
- Planning drawings: plans, elevations, site and location plans
- 3D views on request
- Tender-ready drawing pack
- Structural calculations coordinated
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.
