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 Cornwall?
In Cornwall, 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). Building costs in the South West are close to the UK average, so the figures for Cornwall are close to our national guide. 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 |
Your quote will depend mainly on:
- Measured survey complexity
- Planning or building regulations stage
- Project size and complexity
- 3D visuals
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 Cornwall
The approval route for Cornwall 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
Handled as part of most architectural drawings:
- Measured survey of the existing house
- Planning drawings: plans, elevations, site and location plans
- Tender-ready drawing pack
- Structural calculations coordinated
- Design options and sketch layouts
- 3D views on request
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.
