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 Mid Glamorgan?
In Mid Glamorgan, a set of architectural drawings typically costs £1,500–£4,250 for planning and building regulations drawings for a typical extension, including VAT at 20% (standard rate). That range is adjusted for Wales, where domestic building work typically costs around 8% below the national average. Council application fees are extra.

Planning and building regulations in Mid Glamorgan
The approval route for Mid Glamorgan is set by planning law in Wales. In Wales drawings are prepared to suit the council’s validation requirements and Welsh building regulations.
The Party Wall etc. Act 1996 applies in Wales, so notices must be served before work on a shared wall, on the boundary, or excavation close to a neighbour’s foundations.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
Handled as part of most architectural drawings:
- 3D views on request
- Measured survey of the existing house
- Building regulations drawings and specification
- Planning drawings: plans, elevations, site and location plans
- Structural calculations coordinated
- Party wall drawings where needed
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.
