Glasgow's defining housing type is the sandstone tenement - the red and blonde stone four-to-six storey blocks that make up most of the West End, Southside and much of the wider city. If you own a tenement flat rather than a house, a conventional kitchen extension usually isn't possible at all, since you don't own the ground beneath or around the building - any real extra space typically has to come from internal reconfiguration or, occasionally, from a rear "back court" arrangement agreed with the other owners in the block.
| Extension size (houses only) | Typical cost |
|---|---|
| Small (up to 15m²) | £18,000-£31,500 |
| Medium (15-25m²) | £31,500-£49,500 |
| Large (25m²+) | £49,500 upwards |
Where a conventional extension is actually possible
Detached and semi-detached houses in areas like Bearsden, Newton Mearns and parts of the Southside further from the tenement core follow more familiar extension rules. Even here, Scotland's planning system is legally separate from England's, administered under its own legislation, so English-focused guides don't reliably apply - always check with Glasgow City Council's planning service directly.
What Scottish building control actually requires
Rather than "building regulations approval" as used in England, Scotland uses a "building warrant" system through the local authority's building standards service - a genuinely different process with its own application and inspection regime, worth knowing the correct term for when you're getting quotes or applying yourself.
