If your house has a narrow strip of unused space running down the side, typically the gap next to a kitchen on a terraced or semi-detached property, a side return extension is one of the most cost-effective ways to add genuinely useful space without extending your garden footprint at all.
RW Builders has built side return extensions for homeowners across York and North Yorkshire for over 15 years. It's a job that rewards local knowledge of older housing stock, since a lot of side returns we work on involve tying new brickwork into a Victorian or Edwardian terrace, which needs a different approach to a modern estate house.
A side return is the strip of land alongside a house, often between the kitchen and the boundary wall or fence, that's usually too narrow to be much use as garden space. Building into it typically widens the kitchen or ground floor living space significantly, and it's very often combined with opening up the existing rear wall so the new side space and the original room become one larger area.
Because a side return extension usually fills in space that was already enclosed by walls or fences on two sides, the structural work tends to be more contained than a full rear extension, though the finish, glazing and internal work are just as involved.
Side extensions have their own set of Permitted Development rules, separate from rear extensions. In general, a side extension can be built without planning permission provided it:
If your property sits on designated land, such as a conservation area, side extensions typically require full planning permission regardless of size, so this is one of the first things we check before quoting. Because side returns are often built alongside a rear extension as part of the same project, we also check how the combined side and rear rules interact, since building beyond both a side wall and a rear wall at once can bring both sets of limits into play. Building regulations approval applies separately in almost every case.
A typical side return project includes:
Because side returns often run alongside a neighbouring property, we also factor in the Party Wall etc. Act 1996 where relevant, which may require formal notice to your neighbour before work starts. We'll flag this at the quote stage if it applies to your project.
A lot of the side return work we take on is in Victorian and Edwardian terraces around York, where the original brickwork can be older, softer, and harder to match than modern brick. We source brick to match the existing property wherever we can, and where an exact match isn't realistic, we'll tell you honestly rather than promising a result we can't deliver. The same applies to detailing like string courses, arched lintels over windows, and decorative brickwork, which are common on older York terraces and worth discussing at the design stage if you want the new work to blend in rather than stand out.
Side return extensions are often quicker to build than a full rear extension of similar internal size, since less of the existing house needs to be opened up. Most straightforward side returns take between 6 and 10 weeks, though this varies depending on whether it's combined with rear extension work, which extends the overall timeline.
We're a family-run team based in York, and we've completed side return extensions for homeowners across the city and in villages including Haxby, Strensall, Poppleton, Tollerton, Shipton and Osbaldwick.
