House Extensions at £2,600/m² inc VAT
Flat rate. Fixed-price contract. No surprises.
A single storey side or rear extension on your home in the Milton Keynes area — built within permitted development, using our advanced Spectra timber frame system. Book now and be finished well before Christmas.
Only 4 spaces remaining at this price — booking fast.
A complete house extension for one fixed price.
With only 4 spaces remaining, we're offering homeowners in the Milton Keynes area a single storey side or rear extension — built within permitted development rules so there's no planning headache — at a flat £2,600 per m² including VAT.
It's a fixed-price contract, not a moving estimate. The figure we agree at the start is the figure you pay at the end — no creeping extras, no end-of-job surprises. One flat per-square-metre rate covering the build itself, with the same standard of work and care that has earned us our five-star reputation locally.
Whether you want a bright open-plan kitchen, a kitchen-diner, a separate dining or living room, a utility space or a new ground-floor bathroom — we'll build it. With 5–6 week build times, customers who book now will be finished well before Christmas.
One assumption: the offer price assumes the build area is accessible for our machinery and plant — i.e. we can get a small digger and delivery vehicles to the spot where the extension will be built (typically via a side gate, driveway or a clear route through the garden). If your site has restricted access, we'll let you know at the free site visit and quote any extra cost upfront, before you commit.
Outside Milton Keynes: we still build, but the flat £2,600/m² rate is reserved for properties in the Milton Keynes area. For projects further afield prices start from £2,700 per m² inc VAT, depending on distance and site logistics — we'll confirm your figure at the free site visit, under the same fixed-price contract.
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.
