Wraparound Extension Builders Leeds
Rear and side combined in one L-shaped build — the biggest gain a single storey can give.
★★★★★ Real Google reviewsFree, no-obligation quotesFully insured
A wraparound extension does what a rear extension and a side return do, in one build — turning the back of the house and the alley beside it into a single L-shaped space. For a Leeds terrace or semi with a narrow side passage doing nothing, it is usually the biggest floor area you can gain without going upwards. With 20 years' experience, CLM Projects builds wraparound extensions that read as part of the original house rather than something bolted on, using premium materials from foundation to finish. One experienced team handles the drawings and planning support, the groundworks, the steels, brickwork matched to your home, roofing and glazing, first and second fix, right through to a watertight handover — so you are never chasing separate trades. We coordinate Building Regulations, work cleanly around your home, and keep you informed at every stage. Fully insured and Leeds-based. Start with a free, no-obligation quote.

FAQs
Wraparound Extensions — Your Questions
What is a wraparound extension?
It combines a rear extension with a side return in one build, so the new space wraps around the corner of the house in an L shape. It is the usual way to make a narrow Victorian or 1930s plan feel genuinely open, because you gain the width of the side passage as well as the depth at the back.
Do I need planning permission for a wraparound extension in Leeds?
More often than a straightforward rear extension. Permitted development treats the rear and the side separately, and a wraparound frequently exceeds what the side allowance permits — particularly on a semi. It is always subject to conditions and to your specific property, so we confirm the position with Leeds City Council and handle the drawings and any application for you.
How long does a wraparound extension take to build?
Longer than a single rear extension, because there is more groundwork, more roof and usually more steel. We give you a clear programme with your quote based on your actual plan, ground conditions and finish, rather than a number that sounds good.
Will it affect my neighbour?
The side return usually runs along or close to the boundary, so the Party Wall Act generally applies and your neighbour has to be served notice. We prepare that properly as part of the job — it is a formality when handled early and a genuine hold-up when it is not.
Won't the middle of the house end up dark?
That is the real design question with an L-shaped plan, and it is why rooflights or a lantern usually go over the deepest part rather than nearest the garden. We work the light in at drawing stage instead of leaving it to be solved with lamps afterwards.
Can I stay in my home during the build?
In most cases, yes. A wraparound affects more of the ground floor than a rear extension does, so we plan the works to keep the rest of the house usable and leave the site clean and respectful each day.
