Homes in Ayrshire
Housing in Scotland includes tenements in the cities, sandstone villas, inter-war and post-war semis and a large number of bungalows, which often suit dormer and upward extensions.
What goes into a side return extension?
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.
- Building warrant application and completion certificate
- Glazed or solid roof with rooflights
- Underfloor heating ready screed if wanted
How much should I budget for a side return extension?
What side return extensions typically cost. These are guide ranges; the written quote for your house replaces them.
| Side return extensions | Guide price incl. VAT |
|---|---|
| Standard specification | £3,350 to £3,700 per m² |
| Good specification | £3,700 to £4,150 per m² |
| High specification | £4,150 to £4,550 per m² |
Do you need permission for a side return extension in Largs?
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 can change the price or programme?
- Glazed roofs need careful detailing against the neighbour’s wall.
- Many terraces sit in conservation areas, where side extensions need planning permission.
From first call to completion
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.

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

About 10 to 14 weeks on site.
