House Extensions from £2,500/m² inc VAT
A single storey side or rear extension on your home in Milton Keynes — built within permitted development, using our advanced Spectra timber frame system.
A complete house extension for one fair price.
For a limited time we're offering the first 20 customers a single storey side or rear extension on their property in Milton Keynes — built within permitted development rules so there's no planning headache — for a flat £2,500 per m² including VAT.
Whether you want a bright open-plan kitchen, a kitchen-diner, a separate dining or living room, a utility space or a new bathroom — we'll build it. The price is for the build itself, with the same standard of work and care that has earned us our five-star reputation locally.
Twenty years in the building trade — every part of it. Since 2025 we've focused exclusively on home extensions, and that combination of all-round expertise and a single focus is why we can confidently price work this way.
Spectra Extensions — engineered, not improvised.
A modern building method that looks completely traditional from the outside.
Built in 5–6 Weeks
Precision-engineered timber frame combined with the RADIX screw pile foundation system. No long concrete cures, no months of disruption.
Solid Brick Finish
Real brick outer walls on a structural timber frame — indistinguishable from a traditional build, but lighter on the foundations and the planet.
Building Control Approved
Every extension is individually engineered by structural experts and registered with Building Control from day one — inspections, certificate, everything.
Permitted Development
Most single storey side and rear extensions fall within permitted development rules, which means no planning application and no planning delays.
Common uses: kitchen, kitchen-diner, dining room, living room, family room, utility, ground-floor bathroom — or simply more living space.
Twenty years in the trade. Now extensions only.
