Rear, side return and wrap-around extensions across London, built by one team from the footings up. MPRMatei Limited handles the groundwork, structure, brickwork and every trade inside, so your new room is dug out, built, wired and plumbed on one point of contact.

Single and double storey rear extensions and side returns, from footings and steels through to a finished, plastered room.
Foundations dug and poured, steels set and blockwork built to the engineer’s drawings, signed off through building control.
Brickwork, carpentry, electrics and plumbing all handled by us, so the whole extension runs on one programme.
Roofed, glazed, plastered and decorated, handed over as a room you can move straight into, not a shell.
Many single storey rear and side return extensions fall under permitted development, but conservation areas, Article 4 directions and larger builds often need a full application. We tell you honestly where your job sits and can work alongside your architect or drawings.
Yes. We set the steels to the structural engineer’s design and work to building control sign-off at each stage, from foundations through to completion.
Usually yes. We seal the works off from the rest of the house, keep the kitchen or bathroom usable where we can, and keep the site tidy at the end of each day.
A typical single storey rear extension runs from around eight to twelve weeks depending on size, groundwork and finishes. We give you a realistic programme with the quote.
