Glasgow and the Clyde
Two-storey rear extensions in Glasgow and the Clyde
A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We design and build rear extensions across Glasgow and the Clyde, from Glasgow and Paisley to Greenock, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Two-storey rear extensions suit semi-detached houses in Glasgow best, where the extra bedroom matters as much as the bigger kitchen. Glasgow and the Clyde has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.

Do you need planning permission in Glasgow and the Clyde?
Scottish Class 1B rights for extensions of more than one storey need a 10 metre gap to every boundary, which few gardens have. Expect a planning application as well as a building warrant for a double-storey rear extension.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent.

FAQ
Questions people ask
Does a two-storey rear extension need planning permission?
Almost always. England and Northern Ireland allow 3 metres without an application only if at least 7 metres remains to the rear boundary; Wales and Scotland are similar or stricter.
Is two-storey cheaper per square metre than single-storey?
Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.
Can I add an en-suite upstairs?
Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.
Do you cover all of Glasgow and the Clyde?
We cover 19 towns and districts in Glasgow and the Clyde, including Glasgow, Paisley and Greenock.
