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 Northampton?
In Northampton, 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). We start from a UK-wide guide and adjust it for the East Midlands, where labour and materials are typically about 5% below average. 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 |
What moves the price most:
- Planning or building regulations stage
- Structural engineer’s fees
- Project size and complexity
- 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 Northampton
Before anything is built in Northampton, we confirm which approvals apply 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
What we take care of:
- Planning drawings: plans, elevations, site and location plans
- Design options and sketch layouts
- 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.
