West Yorkshire
Extension builders in Leeds
Plumbery is a London company. We travel to Leeds, about 170 miles away, for complete projects rather than small repairs, and keep one project lead as your contact throughout.
Leeds back-to-back terraces have no rear wall to build from, so extending them usually means a loft or a careful side or front addition. Through-terraces and semis in Chapel Allerton and Roundhay are the ones that suit a rear kitchen extension.
What we do
Typical briefs we get from Leeds
Wraparound extension
Side-return and rear extension combined into one L-shaped open-plan room.
Side-return extension
Filling the side passage of a terrace or semi to widen a narrow kitchen.
Glazed rear extension
Full-width glazing, slim-frame doors and a roof lantern, with the heating sized for the glass.
Kitchen extension
A larger kitchen-diner at the back of the house with roof lights and sliding or folding doors.
Our clients
Built and fitted out by one team
We focus on homeowners in Roundhay, Alwoodley, Adel, Headingley and Chapel Allerton who want the job done properly once: considered layout, quality materials and trades that turn up in the right order.
Headingley, Roundhay and Chapel Allerton include conservation areas where stone or matching brick and slate are expected, so we match materials to the house and the street.
Cost and time
How much and how long
A single-storey rear extension typically takes around 10 to 16 weeks on site once approvals are in place. Use the house extension cost calculator for a budget with VAT, or read how we run extensions on our London house extension page.
Local know-how
Rules and conditions in Leeds
Whether you need planning permission depends on the house type, the depth and height of the extension and whether you are in a conservation area. Many rear extensions fit permitted development; the rest go to Leeds City Council, and every extension needs building regulations approval.
Questions
House extension in Leeds: your questions
Can I extend a Leeds back-to-back house?
Not to the rear, because back-to-backs share their back wall. A loft conversion or a small side or front addition is usually the option, subject to planning.
Which parts of Leeds do you cover?
Yes. We take on complete house extension projects across Leeds, including Headingley, Roundhay, Chapel Allerton, Horsforth, Meanwood and Moortown, and in Roundhay, Alwoodley, Adel, Headingley and Chapel Allerton.
Do I need a party wall agreement?
If you build on or near a shared wall or boundary, or dig foundations close to a neighbour, the Party Wall etc. Act 1996 requires you to serve notice.
Can you also fit the kitchen in the extension?
Yes. We build the extension and fit the kitchen, plumbing, electrics and heating, so one team is responsible for the whole job.
How long does a house extension take?
A single-storey rear extension usually takes around 10 to 16 weeks on site, plus time for drawings and approvals beforehand.
