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 Portslade?
In Portslade, 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 Portslade are adjusted to reflect that. Council application fees are extra.

Planning and building regulations in Portslade
The approval route for Portslade 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.
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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
