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 Streatham?
In Streatham, 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). We start from a UK-wide guide and adjust it for London, where labour and materials are typically about 30% above 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:
- Measured survey complexity
- 3D visuals
- Project size and complexity
- Planning or building regulations stage
A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Planning and building regulations in Streatham
Before anything is built in Streatham, 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:
- Measured survey of the existing house
- Tender-ready drawing pack
- Structural calculations coordinated

- 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.
