Typical extension price
A 25 m² single-storey rear extension in Leeds typically runs £46,000-£70,000 (standard to premium, 2026). Stone-fronted back-to-back conversions in Headingley/Burley run £40,000-£62,000.
Building Control
Leeds Building Control is the council's in-house service; lead time 3-5 working days. Private Approved Inspectors are heavily used in LS6, LS7, LS8 and LS17 where competition is fiercest.
Conservation & Article 4
Leeds has 70+ conservation areas including Headingley, Far Headingley, Roundhay, Chapel Allerton and Adel. Article 4 directions in parts of Headingley remove permitted development rights for HMO use and external alterations.
Local quirks that move the price
Yorkshire-stone front elevations across LS6/LS7/LS17 mean matching reclaimed stone is mandatory — budget £80-140/m² for stone vs £35-60/m² for brick. Historic mineworkings across south Leeds (LS10, LS11, LS27) require Coal Authority searches and sometimes grout-up at £4-10k. Heavy clay soils east of the city centre often need 1.5 m+ foundations.
