Frequently Asked Questions — Extension Builders in Perth
Do I need a building warrant for an extension in Perth?
Yes — almost all extensions in Scotland require a building warrant from your local council. This is separate from planning permission. Your builder should handle the building warrant application, working with a structural engineer for drawings and calculations.

A single-storey rear extension typically costs £1,200–£1,800 per square metre; two-storey £1,000–£1,500 per sqm. A typical 4m × 5m single-storey extension might cost £25,000–£45,000 all-in. Always get at least 3 detailed quotes.
Do Perth extension builders cover surrounding areas?
Yes — most extension builders based in Perth cover the wider district including Stirling, Dunblane, Alloa, Dunfermline and surrounding areas. Some also cover the wider Central Belt.
What qualifications should an extension builder in Perth have?
