What is 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.

How is architectural design and planning approved in Caerphilly?

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.
