Glasgow and the Clyde
Glazed and glass-box rear extensions in Glasgow and the Clyde
Full-height glass, slim frames and big rooflights for the most open rear room. Across Glasgow and the Clyde we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Glasgow, Paisley and Greenock.
A wide sliding door with one long rooflight, rather than a fully glazed roof, keeps a glass-led extension usable in summer. Post-war semis and terraces are common around Glasgow and the Clyde, and many have room for a single-storey rear extension within Class 1A limits.
How much does a glazed rear extension cost in Glasgow and the Clyde?
For Glasgow and the Clyde we work from the Scotland rate: £2,660–£4,560 per square metre of new floor, including VAT, standard specification. Prices in Scotland sit a little below our West Midlands baseline; building warrant fees and drawings are budgeted separately.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £32,000–£54,500 |
| 4 m wide × 6 m deep (24 m²) | £64,000–£109,500 |
Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission in Glasgow and the Clyde?
In Scotland a single-storey rear extension can be permitted development under Class 1A: eaves no higher than 3 metres and an overall height of 4 metres, and where any part is within 1 metre of a boundary it can project no more than 3 metres on a terraced house or 4 metres on other houses. The rights do not apply in conservation areas, and a building warrant is still needed before work starts.
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.

Can I have a level threshold?
Yes, with a drainage channel outside the doors and the slab set to the patio level.
