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 Perth?
In Perth, 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 Scotland are close to the UK average, so the figures for Perth are close to our national guide. 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 main things that change the cost:
- Planning or building regulations stage
- Measured survey complexity
- Number of design options
- 3D visuals
Use the guide price tool to see how size and specification change the figure, then ask for a written, itemised quote.
Planning and building regulations in Perth
Whether you need planning permission depends on your house and its location in Scotland. In Scotland drawings are prepared for the planning application and the building warrant, which must be granted before work starts.
In Scotland a building warrant is needed before work starts on most extensions, loft conversions and conversions. It is issued by the council’s building standards service. When the work is finished, a completion certificate is submitted and accepted by the council after inspection.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
What we handle
From survey to sign-off, the job normally involves:
- Tender-ready drawing pack
- Design options and sketch layouts
- Written agreement with neighbours on shared walls
- 3D views on request
- Structural calculations coordinated
- Building regulations drawings and specification
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.
