Side Return Extensions · Hertfordshire

Make use of every inch of your home's footprint.

A side return extension transforms the narrow passage beside your home into bright, usable open plan space, adding depth, light and a whole new way to enjoy your ground floor.

Discuss Your Side Return Extension

Beautiful homes. More space. Expertly built.

The Opportunity

That narrow side passage is wasted space.

Many terraced and semi detached homes have a narrow strip of land down one side that's too small to enjoy and too useful to ignore. It collects bins, sheds and forgotten things, while inside, the kitchen feels cramped and the layout doesn't flow.

A side return extension puts that space to work. By building into the passage, you can widen your ground floor, open up the kitchen, and create a light filled space that connects properly to the rest of your home and garden.

Before you assume you need to move for a bigger kitchen, let's see what your side return could become.

FAQS

Side return extension questions, Answered.

What is a side return extension?

A side return extension builds into the narrow passage of land that runs alongside many terraced and semi-detached homes, turning unused outdoor space into a wider, brighter ground floor.

Many side return extensions fall under Permitted Development, but it depends on the size, height, materials and whether your home is in a conservation area. We'll advise on what applies to your property.

Yes — combining the two creates a wrap-around extension, which can dramatically increase your ground floor space. This is a popular choice for open-plan kitchen and living areas.

Costs depend on the size, level of finish, glazing and whether it's combined with a rear extension. We'll provide a clear, itemised quote after assessing your property and discussing what you'd like to achieve.

A typical side return extension takes several weeks of construction, depending on complexity and finishes. We'll give you a realistic timeline before work begins.

Yes. Rooflights and glazed walls are a popular way to bring natural light deep into a side return extension, which would otherwise sit between your home and the neighbouring property.

Yes. Air conditioning can be incorporated into your extension as part of the overall design and build. This can be particularly useful for larger open-plan spaces, rooms with lots of glazing, or south-facing extensions that can become warmer during the summer.

Planning the system alongside the extension also means pipework, electrics and indoor units can be considered from the outset, helping to achieve a much cleaner and more discreet finish.

Yes. An extension can be a great opportunity to consider upgrading your home's heating system, including the installation of an air source or ground source heat pump.

The government's Boiler Upgrade Scheme currently provides grants towards eligible heat pump installations in England. Depending on the system and your property's circumstances, grants of up to £9,000 are currently available to help towards the cost of installation.

Eligibility criteria apply, so we can help you consider a heat pump as part of the wider extension project and work alongside an appropriately qualified installer where required.

A well-designed side return extension can significantly improve both the value and liveability of your home, particularly when it creates a modern open-plan kitchen and dining space.

That's completely normal. We'll explore what's possible for your home and help you decide — with no pressure.

  • A bright dining space filled with natural light
  • Room to cook, eat and relax together without feeling crowded
