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 Watford?
In Watford, a set of architectural drawings typically costs £1,500–£4,750 for planning and building regulations drawings for a typical extension, including VAT at 20% (standard rate). Building costs in the East of England run about 6% above the UK average, and the figures for Watford are adjusted to reflect that. Council application fees are extra.
| Size or type | Guide range |
|---|---|
| Planning and building regulations drawings for a typical extension | £1,500–£4,750 |
| Larger or more complex projects | £4,750–£6,000 |
Your quote will depend mainly on:

Planning and building regulations in Watford
Here is how the rules work for a set of architectural drawings 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.
