Semi-detached rear extension in Cambuslang
Semi-detached rear extension in Cambuslang: single or two-storey extensions for semi-detached houses, with side access and one party wall. We measure the house, show you what the rules allow, price it in writing and build it.
We cover Cambuslang (G73) as part of our Lanarkshire work. Where a Cambuslang semi already has a small lean-to at the back, we usually replace it rather than extend it.

Do you need planning permission for a semi-detached rear extension in Cambuslang?
Planning for a semi-detached rear extension in Cambuslang 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.
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.
Scotland has no larger-extension prior approval route; extensions beyond permitted development need a planning application.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Cambuslang like to extend?
Cambuslang 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.

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
