Homes in Gwynedd and Anglesey
Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.
What goes into architectural design and planning?
Designing and building under one roof means the drawings are priced as they are drawn, so there are fewer surprises when the quote arrives. If you only need drawings and a planning application, we can do that and you are free to use any builder.
- Planning and building regulations checks under Welsh rules
- Design options and 3D views
- Structural engineer’s calculations
How much should I budget for architectural design and planning?

What approvals does architectural design and planning need in Wales?
In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.
We prepare applications to Welsh councils and check the Welsh permitted development rules, which differ from England's.
What should I think about before starting?
- Pre-application advice from the council can help on sensitive sites.
- Conservation areas and listed buildings need extra design care and supporting statements.
What are the steps?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
