What is a set of architectural drawings?
Architectural design turns your ideas into drawings that a council and a builder can work from. It starts with a measured survey of the house, then design options, planning drawings and, once approved, detailed building regulations drawings and specifications.

In Powys, a set of architectural drawings typically costs £1,500–£4,250 for planning and building regulations drawings for a typical extension, including VAT at 20% (standard rate).

Planning and building regulations in Powys
Before anything is built in Powys, we confirm which approvals apply in Wales. In Wales drawings are prepared to suit the council’s validation requirements and Welsh building regulations.
Building regulations in Wales are set by the Welsh Government. Approval comes from the council’s building control service or a registered building control approver, with inspections during the work and a completion certificate at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
