What goes into 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.
- Planning and building regulations checks under Welsh rules
- Design options and 3D views
- Submission and liaison with the planning officer

How is architectural design and planning approved in Colwyn Bay?
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
We prepare applications to Welsh councils and check the Welsh permitted development rules, which differ from England's.
What can affect architectural design and planning?
- Pre-application advice from the council can help on sensitive sites.
- Conservation areas and listed buildings need extra design care and supporting statements.
How does the project run?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
