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 Slough?
In Slough, a set of architectural drawings typically costs £1,750–£5,000 for planning and building regulations drawings for a typical extension, including VAT at 20% (standard rate). Prices across the South East are typically 12% above the UK average for this kind of work, which is reflected in the range for Slough. Council application fees are extra.
| Size or type | Guide range |
|---|---|
| Planning and building regulations drawings for a typical extension | £1,750–£5,000 |
| Larger or more complex projects | £5,000–£6,250 |
What moves the price most:
- Measured survey complexity
- Project size and complexity
- Number of design options
- Planning or building regulations stage
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Planning and building regulations in Slough
Here is how the rules work for a set of architectural drawings 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
Handled as part of most architectural drawings:
- Party wall drawings where needed
- Planning drawings: plans, elevations, site and location plans
- Design options and sketch layouts
- Tender-ready drawing pack
- Structural calculations coordinated
- 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.
