Glazed rear extension in Glasgow
For homes in Glasgow, a glazed rear extension is often the simplest way to gain space without moving. Full-height glass, slim frames and big rooflights for the most open rear room. We take it from survey to completion certificate.
Glasgow is covered from our Glasgow and the Clyde round, including G5, G11, G40 and G43. Glass-led rear extensions in Glasgow are planned around which way the garden faces, because that decides the glass specification.

How much does a glazed rear extension cost in Glasgow?
For Glasgow 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 |
We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission for a glazed rear extension in Glasgow?
Planning for a glazed rear extension in Glasgow follows the Scottish householder rules.
Scottish householder permitted development (Class 1A) covers many single-storey rear extensions, with a 3 metre eaves limit, a 4 metre height limit and, within 1 metre of a boundary, a depth limit of 3 metres for terraced houses or 4 metres for others. Conservation areas are excluded, and you need a building warrant whatever the planning position.
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. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application, plus the building warrant.
What are homes in Glasgow like to extend?
Glasgow has sandstone tenements, terraced houses and villas closer in, with post-war semis and newer estates further out. Tenement and other flats need planning permission for an extension, and every project needs a building warrant before work starts.
