Scottish homes range from city tenements and sandstone terraces to bungalows and modern estates, and the building warrant process shapes the programme for every project.
What is included in a side return extension in Irvine?
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.
- Structural steel to remove the side wall
- Underfloor heating ready screed if wanted
- Plastering and making good to the old house

What approvals does a side return extension need in Scotland?
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.
What can affect a side return extension?
- Access is often through the house, so we plan deliveries and protect floors.
- Glazed roofs need careful detailing against the neighbour’s wall.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
