The extension at the top of this page was built in Westcroft. Nine metres wide. Three point three metres deep. Full ground-floor underfloor heating. Premium aluminium bi-fold doors opening directly onto the garden. A luxury kitchen that the client describes — in their own words on video — as changing the way the family uses the house entirely. It is the kind of result that takes a good plot a clear brief and a build team that knows what it is doing.
Westcroft gave us all three. And it is not an accident that some of our finest work has been done here.
Why Westcroft Works for Extensions
Westcroft sits in the south-west of Milton Keynes between Furzton and Shenley Brook End. The detached and semi-detached homes built here through the 1980s and 1990s tend to sit on generous plots with good rear garden depth — exactly the kind of space that makes a single storey rear extension worth doing properly rather than just adequately. A nine metre rear wall with bi-fold doors requires a plot that can carry it. Most Westcroft detached properties can.
Semi-detached homes in the area are equally well suited. The most common brief we receive from Westcroft homeowners is an open-plan kitchen and living space with glazed doors connecting to the garden — a project that falls within Permitted Development for most properties and requires no planning application before work begins.
Our RADIX System in Westcroft
The ground in Westcroft — like much of south-west MK — carries clay-bearing subsoil that makes traditional concrete strip foundations slower and more disruptive than they need to be. Our RADIX screw pile system replaces that process entirely. Steel piles go in on a single day. No concrete. No excavation. No waiting two to three weeks for ground to cure before anything can be built on top. The Westcroft project went from pile installation to finished extension in six weeks on site.
Planning Permission in Westcroft
Most single storey rear and side extensions in Westcroft fall within Permitted Development. Detached houses can extend up to 4 metres to the rear without a planning application. Semi-detached properties are permitted up to 3 metres. We confirm your exact position at the initial site visit before any design work begins.

See the Westcroft Project
The Westcroft luxury rear extension has thirteen photographs and a customer video testimonial. The client walks through the process from the first conversation to the day the bi-fold doors opened for the first time. It is worth watching before you speak to any builder — not because it sells Spectra but because it shows honestly what a well-run extension project in MK actually looks and feels like to live through.
