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.

The biggest cost drivers are:

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 Blackwood
Before anything is built in Blackwood, we confirm which approvals apply 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
What we take care of:
- Design options and sketch layouts
- Measured survey of the existing house
- Planning drawings: plans, elevations, site and location plans
- Structural calculations coordinated
- Party wall drawings where needed
- Building regulations drawings and specification
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.
