Transform the narrow alley alongside your Victorian or Edwardian terrace into stunning open-plan kitchen-dining space. Expert design, structural engineering, and full project management across North West London.
A side return extension fills in the narrow strip of land that runs alongside a typical Victorian or Edwardian terraced house. Often just 1–2 metres wide, this space is one of London's most underutilised assets. When incorporated into the main ground floor, it dramatically widens the kitchen or dining area, creating a bright, open-plan living space without encroaching on your garden.
Designed specifically for Victorian and Edwardian terraces prevalent across Hampstead, Camden, Islington, and North London. We understand the unique structural and planning requirements of these period properties.
Glazed roofs, roof lanterns, and full-width glazing allow daylight to flood into previously dark rear rooms. A well-designed side return extension can transform a gloomy Victorian kitchen into a sunlit, contemporary space.
Side return extensions typically add 10–15% to property values in North London. With average costs starting from £40,000, the investment is recouped quickly in a buoyant London property market.
Many single-storey side return extensions fall within Permitted Development rights, meaning no planning permission is required. We assess your property and advise on the planning route from day one.
Merge your kitchen, dining room, and garden access into one flowing, open-plan living space. We integrate bi-fold doors, kitchen islands, and bespoke joinery as part of a complete design and build package.
Our in-house architects and interior designers create a scheme tailored to your home and lifestyle. From heritage-sensitive additions to bold contemporary contrasts, we deliver spaces that feel right at home.
