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 Leigh?
In Leigh, 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). Building costs in the North West run about 6% below the UK average, and the figures for Leigh are adjusted to reflect that. 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 |
The main things that change the cost:
- 3D visuals
- Number of design options
- Structural engineer’s fees
- Measured survey complexity
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 Leigh
Approvals for a set of architectural drawings in Leigh follow the rules for 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
