Single-storey kitchen extensions: an amazing inspo gallery

single-storey kitchen extensions

The simplest type of extension – the single-storey kitchen extension. Imagine what you could do with a whole new space to the back of your property. Not surprisingly, there are so many options. From open-plan to broken-plan; sky lights to full-length glazed doors; modern or traditional. But that’s the exciting bit, right?

So: single-storey kitchen extensions are a great option for a home with a large enough garden to steal some space from. If they go less than three metres from the rear wall of the original house (or under four metres on a detached property) then you don’t need formal planning permission. You can build under permitted development rights – wahey! Don’t forget to consult your local planning authority first though and also check out Planning Portal for extra advice.

There are some truly amazing single-storey kitchen extensions out there to swoon over, so let me show you my favourite incredible projects…

single-storey kitchen extensions
Firstly, feast your eyes on this beauty.
Single-storey kitchen extensions: Firstly, a rear extension to this terraced house in Wimbledon creates an open-plan kitchen-living-diner. The owners sought planning permission for a 4m-long design with bi-fold doors and skylights. The project, by Vorbild Architecture, forms part of a complete home refurbishment that cost around £300,000. A combination of bi-fold doors and large skylights allows light to flood in.

Single-storey kitchen extensions: Secondly, this kitchen extension in Barnes, south west London, embraces the property’s urban surroundings. Plywood is combined with raw steel and concrete worktops, with units painted in Little Greene’s Three Farm Green for warmth. Rattan lampshades and furniture combine with an upcycled mix of coloured chairs in the informal living area. Kitchens from The Main Company start from £25,000.
a breakfast bar and island
Single-storey kitchen extensions: Thirdly, a linear layout works well in a kitchen extension, shown in this design by John Lewis of Hungerford. A clear path has been left between the island and wall units, also creating uninterrupted sightlines towards the angled picture window. A breakfast bar divides the space horizontally, which helps with zoning. The Shaker kitchen in Blake Blue starts from £28,000.

Single-storey kitchen extensions: Fourthly, we come to my favourite of this amazing single-storey extensions gallery. The owners of this south west London home wanted to create an industrial loft style in their new extension. A pitched roof, steel-framed glazing, and exposed brickwork form the shell of the new addition. They used textures of rough sawn oak and matt lacquered units painted in Farrow & Ball’s Railings in the kitchen. The design shown is Roundhouse’s Classic painted kitchen and Urbo handleless cabinetry, with worktops in Nero Granite with a Linen finish. Roundhouse bespoke kitchens start at £35,000. The extension was designed by 50degrees North Architects. 
bold yellow steel beams
Single-storey kitchen extensions: Fifthly, a simple way of achieving wow factor is to expose and showcase the structural elements of the build. In this extension to the home of Woodrow Architects’ founder in Hampton Hill, bold yellow steel beams, over-sailing timber rafters and plywood furniture create warm and playful spaces. The project, which included reconfiguring the entire ground floor and garden, cost £150,000. The kitchen cost around £8000, with carcasses and fronts from Ikea and worktops, bench and bespoke joinery all white oiled birch plywood.
