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 Bristol?
In Bristol, 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 Bristol 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 |

The main things that change the cost:
- Project size and complexity

- Planning or building regulations stage
- Number of design options

Planning and building regulations in Bristol
Before anything is built in Bristol, we confirm which approvals apply 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.
We check this for your address before design work starts, so there are no surprises later.
