Architectural design and planning in Holyhead

Covering Holyhead

Alongside Holyhead, we also cover Llangefni, Caernarfon (19 miles to the south-east) and Bangor.

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 does architectural design and planning involve?

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.

Do you need permission for architectural design and planning in Holyhead?

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 Holyhead homeowners check first?

Planning and building regulations are separate approvals; most projects need building regulations even when planning is not needed.
Pre-application advice from the council can help on sensitive sites.
