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 Monmouth?
In Monmouth, 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). Building costs in Wales run about 8% below the UK average, and the figures for Monmouth are adjusted to reflect that. Council application fees are extra.
| Size or type | Guide range |
|---|---|
| Planning and building regulations drawings for a typical extension | £1,500–£4,250 |
| Larger or more complex projects | £4,250–£5,250 |
The biggest cost drivers are:
- Planning or building regulations stage
- Structural engineer’s fees
- Measured survey complexity
- 3D visuals
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 Monmouth
Here is how the rules work for a set of architectural drawings in Wales. In Wales drawings are prepared to suit the council’s validation requirements and Welsh building regulations.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, 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:
- Planning drawings: plans, elevations, site and location plans
- Building regulations drawings and specification
- 3D views on request
- Measured survey of the existing house
- Tender-ready drawing pack
- 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.
