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 Bletchley?
In Bletchley, 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). That range is adjusted for the South East, where domestic building work typically costs around 12% above the national average. 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 |
The main things that change the cost:
- 3D visuals
- Planning or building regulations stage
- Structural engineer’s fees
- Number of design options
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 Bletchley
The approval route for Bletchley 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
From survey to sign-off, the job normally involves:
- Design options and sketch layouts
- Planning drawings: plans, elevations, site and location plans
- 3D views on request
- Building regulations drawings and specification
- Structural calculations coordinated
- Tender-ready drawing pack
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.
Building in Bletchley
Commuter towns across the South East have many 1930s and post-war semis that suit rear extensions and hip-to-gable loft conversions.
From MK3 outwards, we take on projects throughout Bletchley and the surrounding parts of Buckinghamshire.

Questions about architectural drawings in Bletchley

Not necessarily. For extensions and lofts, an architectural technician’s drawings are common. For complex or sensitive sites, an architect may be better.
What are building regulations drawings?
More detailed drawings and specifications showing structure, insulation, fire safety, drainage and ventilation, used for building control approval and pricing.
