Forth Valley
Pitched and lean-to roof rear extensions in Forth Valley
Lean-to, gable and hipped roofs that give a vaulted ceiling. We design and build rear extensions across Forth Valley, from Stirling and Falkirk to Alloa, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Pitched roofs suit the cottages and slate-roofed houses in parts of Forth Valley. Post-war semis and terraces are common around Forth Valley, and many have room for a single-storey rear extension within Class 1A limits.
How much does a pitched-roof rear extension cost in Forth Valley?
A pitched-roof rear extension in Forth Valley is priced at £1,900–£3,090 per square metre including VAT as a guide, before kitchen fit-out and fees. Prices in Scotland sit a little below our West Midlands baseline; building warrant fees and drawings are budgeted separately.

Conservation areas are excluded, and you need a building warrant whatever the planning position.
