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 Morden?
In Morden, a set of architectural drawings typically costs £2,000–£5,750 for planning and building regulations drawings for a typical extension, including VAT at 20% (standard rate). Building costs in London run about 30% above the UK average, and the figures for Morden are adjusted to reflect that. Council application fees are extra.
| Size or type | Guide range |
|---|---|
| Planning and building regulations drawings for a typical extension | £2,000–£5,750 |
| Larger or more complex projects | £5,750–£7,250 |
The biggest cost drivers are:
- Structural engineer’s fees
- 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 Morden
Whether you need planning permission depends on your house and its location 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.
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
- 3D views on request
- Structural calculations coordinated
- Party wall drawings where needed
- Planning drawings: plans, elevations, site and location plans
- Measured survey of the existing house
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.
