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.
How much does a set of architectural drawings cost in Carmarthen?
In Carmarthen, 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). We start from a UK-wide guide and adjust it for Wales, where labour and materials are typically about 8% below average. Council application fees are extra.

Planning and building regulations in Carmarthen
Before anything is built in Carmarthen, 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.
