Homes in Ayrshire

In Scotland many families extend bungalows and semis, while tenement flats bring shared ownership of roofs and walls that needs agreeing early.

What does a side return extension involve?

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 Kilmarnock?

In Scotland the key step is the building warrant, which must be granted before work begins. Planning permission is decided separately by the council, and work on shared walls is handled under your title deeds rather than a party wall act.

Scotland has its own householder permitted development rules, and small single-storey rear extensions are often covered.

What should Kilmarnock homeowners check first?

Glazed roofs need careful detailing against the neighbour’s wall.
Many terraces sit in conservation areas, where side extensions need planning permission.

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.
