Semi-detached rear extension in Rutherglen
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 Rutherglen and the surrounding area, with one contract from the first survey to building control sign-off.
Rutherglen and its postcode districts G72 and G73 are part of our Lanarkshire coverage. Where a Rutherglen 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 Rutherglen?
Whether your semi-detached rear extension in Rutherglen needs a planning application depends on its size, your house and any local restrictions.
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 Rutherglen like to extend?
Post-war semis and terraces are common around Rutherglen, and many have room for a single-storey rear extension within Class 1A limits.
How a semi-detached rear extension in Rutherglen comes together
Survey visit
We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.
Options and costs
We draw layout options and price each one, so the budget shapes the design rather than surprising you later.
Approvals
Permitted development check or planning application, then building warrant drawings and structural calculations, plus a written agreement with neighbours for any shared-wall work.
Written price, then build
Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

FAQ
Semi-detached rear extension questions in Rutherglen
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.
What if my neighbour has already extended?
That can make a matching depth easier to justify. We measure theirs at the survey.
What postcode areas do you cover around Rutherglen?
Including G72 and G73, and the surrounding Lanarkshire area.
