Building Regulations for rear extensions in Ayrshire
Construction drawings, structural calculations and building control through to the completion certificate. Across Ayrshire we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Kilmarnock, Ayr and Irvine.
Post-war semis and terraces are common around Ayrshire, and many have room for a single-storey rear extension within Class 1A limits.
What does it cost in Ayrshire?
As a guide, £2,500–£5,500 including VAT. These are guide ranges; the written quote after the survey is the figure that counts.
What approvals does it need in Ayrshire?
Scottish extensions are approved by building warrant, granted by the council's building standards team before work begins, with a completion certificate submitted when the work is finished.
Insulation and glazing follow Section 6 of the Scottish Technical Handbook; the building warrant drawings show how the extension meets it.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent.
