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 Bath?
In Bath, 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 Bath reflects that. Council application fees are extra.
| Size or type | Guide range |
|---|---|
| Planning and building regulations drawings for a typical extension | £1,500–£4,500 |
| Larger or more complex projects | £4,500–£5,500 |
The main things that change the cost:

Planning and building regulations in Bath
The approval route for Bath 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.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
What we handle
On a typical set of architectural drawings we handle:
- 3D views on request
- Structural calculations coordinated
- Building regulations drawings and specification
- Measured survey of the existing house
- Design options and sketch layouts
- Planning drawings: plans, elevations, site and location plans
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.
