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 Rhondda?
In Rhondda, 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). That range is adjusted for Wales, where domestic building work typically costs around 8% below the national average. 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 biggest cost drivers are:
- Project size and complexity
- Number of design options
- Measured survey complexity
- Structural engineer’s fees
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 Rhondda
Here is how the rules work for a set of architectural drawings in Wales. In Wales drawings are prepared to suit the council’s validation requirements and Welsh building regulations.
The Party Wall etc. Act 1996 applies in Wales, so notices must be served before work on a shared wall, on the boundary, or excavation close to a neighbour’s foundations.
We check this for your address before design work starts, so there are no surprises later.
What we handle
The work we manage on a set of architectural drawings:
- Design options and sketch layouts
- 3D views on request
- Planning drawings: plans, elevations, site and location plans
- Party wall drawings where needed
- 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.
Building in Rhondda
Terraced houses in Welsh towns often have narrow plots, which suits rear and side return extensions and rear dormers.
