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 Mill Hill?
In Mill Hill, 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). That range is adjusted for London, where domestic building work typically costs around 30% above the national average. 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:
- 3D visuals
- Planning or building regulations stage
- Measured survey complexity
- Number of design options
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 Mill Hill
The approval route for Mill Hill is set by planning law 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.
We check this for your address before design work starts, so there are no surprises later.
What we handle
The work we manage on a set of architectural drawings:
- Building regulations drawings and specification
- Tender-ready drawing pack
- Design options and sketch layouts
- Measured survey of the existing house
- Party wall drawings where needed
- Planning drawings: plans, elevations, site and location plans
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.
