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 Bognor Regis?
In Bognor Regis, a set of architectural drawings typically costs £1,750–£5,000 for planning and building regulations drawings for a typical extension, including VAT at 20% (standard rate). Building costs in the South East run about 12% above the UK average, and the figures for Bognor Regis are adjusted to reflect that. Council application fees are extra.

The biggest cost drivers are:

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 Bognor Regis
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.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
We check this for your address before design work starts, so there are no surprises later.
What we handle
From survey to sign-off, the job normally involves:
- Party wall drawings where needed
- Building regulations drawings and specification
- Planning drawings: plans, elevations, site and location plans
- Design options and sketch layouts
- 3D views on request
- Tender-ready drawing pack
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.
