Semi-detached rear extension in Erskine
Single or two-storey extensions for semi-detached houses, with side access and one party wall. We design, get the approvals for and build rear extensions for semi-detached houses in Erskine and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Erskine (PA4, PA7 and PA8) as part of our Glasgow and the Clyde work. Semi-detached houses are common across Glasgow and the Clyde, and their side access makes rear extensions quicker to build.

Do you need planning permission for a semi-detached rear extension in Erskine?
Here is how the rules in Scotland apply to a semi-detached rear extension in Erskine.
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. 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 Erskine like to extend?
Post-war semis and terraces are common around Erskine, and many have room for a single-storey rear extension within Class 1A limits.
