What is included in a side return extension in Perth and Kinross?

A side return extension builds over the narrow passage that runs beside the back of many Victorian and Edwardian terraced houses, widening the kitchen or dining room by a metre or two. It is usually combined with a glazed or part-glazed roof so the deeper room still gets daylight.

Do you need permission for a side return extension in Perth and Kinross?

Projects in Scotland need a building warrant from the council before any building work starts, and a completion certificate once it is finished. Planning permission is a separate decision. The Party Wall etc. Act does not apply in Scotland; shared walls are governed by title deeds and the law of the tenement where relevant.

Scotland has its own householder permitted development rules, and small single-storey rear extensions are often covered. Whatever the planning position, you need a building warrant from the council before any building work starts, and a completion certificate at the end.

What should I think about before starting?

Access is often through the house, so we plan deliveries and protect floors.
Many terraces sit in conservation areas, where side extensions need planning permission.

How much does a side return extension cost?

Usually about £3,350 to £4,550 per square metre including VAT, which works out at around £35,000 to £55,000 for a typical side return before the kitchen.

Modern solar-control glass and a mix of glazed and solid roof keep it comfortable. We advise on the balance during design.
