Side return extensions in Perth and Kinross
Infilling the narrow passage beside a Victorian or Edwardian back addition. Across Perth and Kinross we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Perth, Blairgowrie and Rattray and Crieff.
In Perth we check the boundary line and the neighbour's gutter before drawing a side return, because a few centimetres decide whether the wall goes on or beside the boundary. Perth and Kinross has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.

A side return extension in Perth and Kinross is priced at £2,180–£3,610 per square metre including VAT as a guide, before kitchen fit-out and fees. Prices in Scotland sit a little below our West Midlands baseline; building warrant fees and drawings are budgeted separately.

Do you need planning permission in Perth and Kinross?
Scottish householder rights treat the side part of a wraparound or side infill more strictly than a plain rear extension, so most need planning permission, and all need a building warrant.
There is no Party Wall Act in Scotland; neighbour matters are handled through the title deeds, common law and written agreement before work starts.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent.

FAQ
Questions people ask
How much space does a side return add?
Typically 8 to 18 square metres, enough to turn a galley kitchen into a kitchen-diner with an island.
Can I combine a side return with a rear extension?
Yes; that is a wraparound extension, and it gives the biggest open-plan room a terrace can have.
Glass roof or solid roof with rooflights?
A glass roof gives the most light; a solid roof with long rooflights is warmer and quieter in rain. Both work.

We cover 5 towns and districts in Perth and Kinross, including Perth, Blairgowrie and Rattray and Crieff.
