House Extensions in Leeds
Single and double storey extensions built from first brick to final fit-out, managed by one team throughout.
Extra Space, Built to Last
An extension is one of the biggest projects you can take on with your home, which is exactly why Matt and the team manage every stage themselves rather than subcontracting it out piecemeal. From groundworks and brickwork through to the roof, windows and internal joinery, the same reliable team sees the job through, so nothing falls between the gaps.
As one customer put it, Matt is her "go to for any work" after he built her extension and refurbished her whole house. That same meticulous, no-job-too-big approach goes into every extension we build.
- Single and double storey rear, side and wrap-around extensions
- Groundworks, brickwork, roofing and structural carpentry
- Windows, doors and bi-fold or French door installation
- Full internal fit-out: plastering, flooring and joinery
- One team and one point of contact from start to finish

House Extensions examples


What to Expect
Every extension begins with a visit to look at the space, talk through how you want to use it and discuss practical points such as access, materials and how the new room will connect to the existing house. You then receive a clear quote, and the plan is agreed before any work starts.
During the build we keep the site safe and tidy, protect the rest of your home and keep you updated, so you always know what happens next. When the job is finished you are left with a bright, well-finished space that feels like part of the original house.

House Extensions questions
Do I need planning permission for my extension?
Many single storey extensions fall under permitted development, but it depends on your property and what you are planning. We will talk through what your project needs during the initial visit, and can point you toward the right planning or building control route.
How long does an extension take?
A single storey extension typically takes eight to twelve weeks from groundworks to a finished, decorated space, depending on size and specification. We will give you a realistic programme with your quote.
Will one team handle the whole project?
Yes. That is the whole point of working with MT Joinery: the same trusted team sees your extension through from groundworks to the final joinery and finishing touches, with one point of contact throughout.
Can you match the extension to my existing house?
Yes. We match brickwork, roof lines, windows and internal joinery as closely as possible so the extension blends in with the original building.
Can you help with the layout?
Yes. We talk through room layouts, window and door positions and how the space will be used, and can work alongside your architect or designer if you have one.
