Do you need planning permission for a glazed rear extension in Alloa?
The planning route for a glazed rear extension in Alloa is set by Scotland's householder rules and your council.
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.
Insulation and glazing follow Section 6 of the Scottish Technical Handbook; the building warrant drawings show how the extension meets it.
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 Alloa like to extend?
Post-war semis and terraces are common around Alloa, and many have room for a single-storey rear extension within Class 1A limits.
