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
- Drainage and new gully positions

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. 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.
