Sheffield has an inter war and post war semi belt on one side, big stone terraces and villas on the other, and published extension guidance with numbers in it.
Sheffield's own extension guidance sets a 45 degree angle to a neighbour's nearest window, 12 metres in front of their ground floor windows and 21 metres between facing windows. We build those into the extension page, give loft conversions their own page at 260 searches a month, and add a page per area. Free live demo, live in 7 days.
The published Valuation Office stock table CTSOP4.1, stock at 31 March 2025, records 262,430 properties in Sheffield. Totalling its build period columns ourselves, 49,770 were built before 1919, which is 19.0%, and 105,570 before 1940. 21.3% of the city is inter war and 25.4% was built between 1945 and 1972.
Census 2021 table TS044 records 38.0% of households in semi detached houses, 26.0% terraced, 17.6% in purpose built flats and 15.0% detached. Our own totals of the Valuation Office build period table put Springvale and Steel Bank at 80.3% pre 1919, Meersbrook at 67.2%, Nether Edge at 62.3%, Broomhall at 61.3% and Broomhill and Lower Crookesmoor at 58.1%.
At the other end of the same table, Herdings and Gleadless Valley is 94.1% built between 1945 and 1972 and Batemoor and Jordanthorpe 92.5%. We would build the loft and renovation pages for the first list and the extension and garage conversion pages for the second, each carrying your own finished jobs.
35.2% built before 1919 and 44.4% inter war, with 4.0% built since 2000 (our own totals of the Valuation Office table, 2025).
Large inter war semis and detached houses taking two storey side and rear extensions, loft conversions with dormers and full reworkings.
62.3% built before 1919 (our own totals of the Valuation Office table, 2025). A conservation area that carries an Article 4 direction, according to the council's conservation areas page.
Victorian villa renovation, loft and basement work, and extensions drawn to a conservation standard.
58.1% built before 1919, with 12.8% built since 2000 (our own totals of the Valuation Office table, 2025). Broomhill is a conservation area with an Article 4 direction.
Big period houses, much of it rented, so conversion, reinstatement and structural work as well as extensions.
Totley and Bradway is 45.5% built between 1945 and 1972 and 21.3% inter war. Dore and Whirlow is 29.2% from 1945 to 1972, 24.9% from 1973 to 1999 and 21.5% inter war (our own totals of the Valuation Office table, 2025). Totley, Dore and Whirlow are all on the council's conservation area list.
Suburban work on generous plots: two storey extensions, garden rooms and garage conversions, with a conservation boundary through part of it.
Meersbrook is 67.2% built before 1919 and Woodseats 48.1%. Herdings and Gleadless Valley is 94.1% built between 1945 and 1972 (our own totals of the Valuation Office table, 2025).

Sheffield City Council's conservation areas page names 38 conservation areas within the city boundary, 35 of them in Sheffield's own planning area, among them Nether Edge, Broomhill, Ranmoor, Fulwood, Dore, Totley, Endcliffe, Norton, Greenhill, Ecclesfield and the City Centre.
Nether Edge and Broomhill carry Article 4 directions. The council's page describes those two directions as removing permitted development rights for solar panels on roof slopes facing a highway, and that is the only effect stated there. Separately, an Article 4 direction that came into force on 10 December 2011 means that within its area "you now need to apply for planning permission to convert a dwellinghouse (Use class C3) into an HMO for 3 to 6 unrelated people".
For extension design the council publishes guidance called Designing House Extensions. It says two storey flat roofed extensions to dwellings with pitched roofs "will not normally be approved if the roofline is clearly visible from the street", and that such an extension is expected to be set back at least 0.5m. It says dormer windows "should not rise above the existing ridge line of a roof, nor dominate the roof plane on which they sit". It sets a 45 degree angle to the nearest point of a neighbour's window, a 12 metre distance in front of a neighbour's ground floor main windows and 21 metres between facing main windows. The same guidance says its advice does not apply to dwellings in conservation areas or to listed buildings, "for which stricter design criteria apply".
We would build a page that carries those figures, explains which jobs need permission, and says that you check the address against the conservation boundary and the two Article 4 directions before you quote.
The local field, 16 September 2026
We counted the Google Maps results for builders in Sheffield on 16 September 2026. The sample was 40 listings: 38 had a website and 2 had none. The same list is padded out with a merchant, a cafe, a boat firm, an interiors company and two developers from outside the city.
That is one dated sample of one search. Presence is not the gap in Sheffield. What we would do with it is give Ecclesall, Nether Edge, Totley, Meersbrook and Gleadless a page each, and a page to each job, carrying your own finished work.
Three Sheffield firms appeared in the first ten Google local listings we checked for "builders in Sheffield", with sites worth opening. This is the bar a building firm here reaches once it puts money into the site.

Built on WordPress. It carries a page per area, photographs of its own jobs and reviews on the page. Quotes come through a form.
The title lists new builds, extensions, kitchens and bathrooms by name and there is a separate new builds Sheffield page, so the site matches the search rather than the firm's own org chart.
One keeps the phone number in the header, all three carry reviews on the page, and two run a page per area. Each one opened and checked 16 September 2026.

The council names 38 conservation areas in the city. Nether Edge and Broomhill also carry Article 4 directions, which the council's page describes as removing permitted development rights for solar panels on roof slopes facing a highway. We would say exactly that on the page, and say you check the address first.
Follow the stock. 21.3% of the city is inter war and 25.4% was built between 1945 and 1972 on the Valuation Office table for March 2025, which is the extension and garage conversion housing. The pre 1919 west and inner south is loft and renovation work. Two markets, two sets of pages.
