Leeds is 80 conservation areas, an HMO Article 4 over 14 named areas, and a design guide that puts a metre figure on a two storey rear extension.
Leeds City Council records 19,500 pre 1919 back to back houses still in use, and loft conversion Leeds runs at 480 searches a month. We build the loft page, the extension page and area pages for Harehills, Headingley, Moortown and Horsforth, with a quote tool that asks whether there are drawings yet. See it live before you pay a penny, live in 7 days.
The published Valuation Office stock table CTSOP4.1, stock at 31 March 2025, records 376,780 properties in Leeds. Totalling its build period columns ourselves, 64,810 were built before 1919, which is 17.2%, and 135,570 before 1940. 28.4% went up between 1945 and 1972 and 16.1% between 1973 and 1999.
The council's Housing Strategy 2022 to 2027 states that "Leeds has a notably large amount of 19,500 pre-1919 back-to-back houses still in use". Census 2021 table TS044 records 37.5% of households in semi detached houses, 25.0% terraced, 17.5% in purpose built flats and 15.5% detached.
Those two lines point at two different books of work. We would show how you handle a loft conversion on a terrace with a shared ridge, and how you handle a rear or side extension on a semi with room beside it, each on its own page with your own finished jobs.
81.0% and 87.1% built before 1919, with almost nothing after 1945 (our own totals of the Valuation Office table, 2025). Both are named in the council's HMO Article 4 direction.
Loft conversions and full renovations on back to back and through terraces, often for landlords and agents. Head height and stair position decide the job.
Headingley is 52.4% built before 1919 and Hyde Park 71.5% (our own totals of the Valuation Office table, 2025). Both are named in the HMO Article 4 direction, and the Householder Design Guide calls Headingley a conservation area in a high density urban environment.
Loft and rear dormer work on terraces, with conversion and reinstatement as the rented stock turns over.
47.9% and 52.7% inter war, with 25.3% and 15.6% built between 1945 and 1972 (our own totals of the Valuation Office table, 2025).
Inter war semis with side space and a garage, taking rear extensions, two storey side extensions and garage conversions.
Horsforth West is 56.0% built between 1945 and 1972, and Horsforth South and Rawdon is 27.8% built before 1919 (our own totals of the Valuation Office table, 2025). Horsforth is named in the HMO Article 4 direction.
Post war semis and detached houses on generous plots taking rear and two storey extensions, with period renovation on the older Rawdon side.
Otley South is 40.4% built before 1919, Wetherby West is 38.7% built between 1973 and 1999 and Wetherby East and Thorp Arch is 28.2% built since 2000 (our own totals of the Valuation Office table, 2025). Otley and Wetherby are both on the council's conservation area list.
Stone renovation and matched extensions inside the conservation areas, and reworking of late century detached houses outside them.
Leeds City Council puts the number of conservation areas in the city at 80, and runs a separate Article 4 direction on houses in multiple occupation covering 14 named areas: Adel and Wharfedale, Armley, Beeston Hill and Holbeck, Bramley and Stanningley, Burmantofts and Richmond Hill, Chapel Allerton, City and Hunslet, Gipton and Harehills, Headingley, Horsforth, Hyde Park and Woodhouse, Kirkstall, Moortown, Roundhay and Weetwood.
For extension work the operative document is the council's Householder Design Guide, adopted as a supplementary planning document. Where an extension sits on a boundary with a neighbour, as on terraced or semi detached houses, it says "a projection of 3.0m is normally acceptable". On first floor work it says an extension on a common boundary "should not project more than 1.0m beyond a neighbouring rear elevation in order to comply with the 45 degree code", and the guide notes that this makes two storey rear extensions difficult on terraces and semis.
The same guide says two storey front extensions will not normally be acceptable, and that rear dormers "should still seek to be set down from the roof ridge, up from the eaves level, and in from the sides" in matching materials.
Those are the sentences a Leeds customer has usually half read somewhere else. We would build a page that quotes them, explains which jobs need permission, and says that you check the address against the conservation boundary and the Article 4 areas before you quote.
The local field, 16 September 2026
We counted the Google Maps results for builders in Leeds on 16 September 2026. The sample was 40 listings: 35 had a website and 5 had none. The same list carries two builders merchants, a kitchen company, a firm based in Wakefield and a contractor from the North West, and several of the strongest ranked listings are property development firms rather than domestic builders.
That is one dated sample of one search. What we would do with it is give Harehills, Headingley, Moortown, Horsforth and Otley a page each, carrying the jobs you have finished in them.
Three Leeds firms appeared in the first ten Google local listings we checked for "builders in Leeds", with sites worth opening. This is the bar a building firm here reaches once it puts money into the site.
A custom site built by an agency. It carries photographs of its own jobs and reviews on the page. It has no page per area. Quotes come through a form, and the phone number sits in the header.
It puts both Google reviews and a Checkatrade badge on the home page, so the proof comes from two places the customer already trusts rather than from the firm's own wording.
Built on Wix. It carries reviews on the page. It has no page per area and no photographs of its own jobs. Quotes come through a form, and the phone number sits in the header.
The page title lists loft conversions, extensions and garage conversions by name, which is exactly what the customer typed, and the phone number follows you down the page.
Built on Wix. It carries photographs of its own jobs and reviews on the page. It has no page per area. Quotes come by phone, and the phone number sits in the header.
Two numbers, an office line and a mobile, sit at the top of every page, which suits a customer who wants to talk about a big job rather than type into a box.
All three keep the phone number in the header, all three carry reviews on the page, and none run a page per area. Each one opened and checked 16 September 2026.

What every building site needs, whatever the town, is on our builders page.
It changes which page they land on. The council's Housing Strategy 2022 to 2027 records 19,500 pre 1919 back to back houses still in use, and our totals of the Valuation Office table put Harehills North and South at 81.0% and 87.1% pre 1919. We would build the loft page for that half of the city and show the stair and head height on a finished job.
Loft conversion Leeds is searched 480 times a month, against 720 for builders in Leeds (OpenSEO keyword data, September 2026). That is a customer who already knows the job they want and is comparing firms. We would give it a page with photographs, building control and a finished room on it.
The council's Householder Design Guide says a first floor extension on a common boundary should not project more than 1.0 metre beyond the neighbouring rear elevation in order to comply with the 45 degree code, and notes this makes two storey rear extensions difficult on terraces and semis. We would put that sentence on the page with a link to the guide.
