Do you need planning permission for a glazed rear extension in High Blantyre?

The planning route for a glazed rear extension in High Blantyre 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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.

What are homes in High Blantyre like to extend?

Post-war semis and terraces are common around High Blantyre, and many have room for a single-storey rear extension within Class 1A limits.

How a glazed rear extension in High Blantyre comes together

  1. Survey visit

    We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.

  2. Options and costs

    We draw layout options and price each one, so the budget shapes the design rather than surprising you later.

  3. Planning and regulations

    We take the design through the right planning route, then produce the construction drawings and engineer's calculations for the building warrant.

  4. Build and sign-off

    We build to the approved drawings with regular updates, then hand over the accepted completion certificate and any guarantees from suppliers.
