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 Horsham?
In Horsham, 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:
- Structural engineer’s fees
- 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 Horsham
Whether you need planning permission depends on your house and its location in England. In England drawings are prepared to suit the local planning authority’s validation list and, later, building control.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
We check this for your address before design work starts, so there are no surprises later.

Questions about architectural drawings in Horsham
Do I need an architect?
Not necessarily. For extensions and lofts, an architectural technician’s drawings are common. For complex or sensitive sites, an architect may be better.
Can I use the drawings with another builder?
Yes. Drawings you pay for are yours to use for the project.
What drawings are needed for planning?
Usually existing and proposed floor plans and elevations, a block plan and a location plan. Some councils need more.
