Single-storey rear extension in Elgin
Single-storey rear extension in Elgin: ground-floor space across the back of the house, usually for a kitchen, dining or family room. We measure the house, show you what the rules allow, price it in writing and build it.
We cover Elgin (IV30) as part of our Highlands and Islands work. A depth of 3 to 4 metres keeps many single-storey rear extensions in Elgin within permitted development, subject to the house's planning history.

Do you need planning permission for a single-storey rear extension in Elgin?
Planning for a single-storey rear extension in Elgin 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.
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 Elgin like to extend?
Elgin has older stone houses, post-war homes and many detached houses and bungalows on larger plots. Wind and rain shape the design: roof pitch, cladding and glazing are chosen for the weather, and every extension needs a building warrant.

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.
