Do you need planning permission for a glazed rear extension in Fort William?
Planning for a glazed rear extension in Fort William 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.
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 Fort William like to extend?
Traditional stone houses sit alongside modern bungalows and timber-frame homes around Fort William. A lighter, contrasting addition at the back often suits older stone houses better than trying to copy the walling.
