What do you get with architectural design and planning?
Architectural design and planning covers everything before building starts: a measured survey of the house, design options, planning or permitted development drawings, the application itself, building regulations drawings and structural calculations. We offer it on its own or as part of a design-and-build project.
- Design options and 3D views
- Submission and liaison with the planning officer
- Structural engineer’s calculations
How much should I budget for architectural design and planning?
Use these ranges to budget for architectural design and planning; the survey turns them into a fixed price for the agreed specification.
| Architectural design and planning | Guide price incl. VAT |
|---|---|
| Measured survey and existing drawings | £500 to £1,200 |
| Planning drawings and application | £1,200 to £3,000 |
| Building regulations drawings and specification | £1,000 to £2,500 |
| Structural calculations | £500 to £2,000 |
What approvals does architectural design and planning need in Scotland?
Scottish projects follow a different process from England: the council issues a building warrant before work starts and accepts a completion certificate at the end, alongside any planning permission needed. We prepare both applications.
We prepare planning applications where needed and the building warrant application, which must be approved before work starts in Scotland.
What can change the price or programme?
- Pre-application advice from the council can help on sensitive sites.
- Conservation areas and listed buildings need extra design care and supporting statements.
From first call to completion
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
