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 Coleraine?
In Coleraine, a set of architectural drawings typically costs £1,250–£3,750 for planning and building regulations drawings for a typical extension, including VAT at 20% (standard rate).

A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Planning and building regulations in Coleraine
Before anything is built in Coleraine, we confirm which approvals apply in Northern Ireland. In Northern Ireland drawings are prepared for the council’s planning service and building control.
In Northern Ireland building control approval comes from the council, usually through a full plans application or a building notice, with inspections during the work and a completion certificate at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
On a typical set of architectural drawings we handle:
- Written agreement with neighbours on shared walls
- Building regulations drawings and specification
- 3D views on request
- Planning drawings: plans, elevations, site and location plans
- Tender-ready drawing pack
- Structural calculations coordinated
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.
