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 Penzance?
In Penzance, 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 Penzance are close to our national guide. Council application fees are extra.
| Size or type | Guide range |

Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Planning and building regulations in Penzance
The approval route for Penzance 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.
