City Information

Northolt sits in the far west of the London Borough of Ealing, right on the A40, about 11 miles from Charing Cross. It grew up around an old village green, and you can still see traces of that history today. St Mary the Virgin church dates back to the 1300s, and the clock tower on the green went up in 1937 to mark the coronation of King George VI. The Grand Union Canal cuts through the area too, giving Northolt a bit of green space that a lot of nearby suburbs do not have.

Most of the town as it looks now was built in the 1920s and 1930s, when Northolt grew quickly as a dormitory town for people working in Ealing and central London. After the war, large council estates went up around Northolt Park, and more recently the Grand Union Village development added new homes and a marina near the canal.

Northolt is served by Northolt station on the Central line, so residents get a direct run into the city without needing a car. The mix of an old village core, solid interwar housing, and newer developments gives the area a character that is quite different from the more central parts of Ealing.

Planning Notes

Planning applications in Northolt are handled by Ealing Council’s Planning and Building Control department, based at Perceval House, 14 to 16 Uxbridge Road, London W5 2HL. You can reach the team on 020 8825 6600, or through the planning pages on the Ealing Council website.

For most homes in Northolt, loft conversions can go ahead under permitted development, which means you do not need full planning permission as long as the work stays within set limits. The general rules follow the national Class B permitted development allowance. This means the extra roof space must not go over 40 cubic metres for a terraced house or 50 cubic metres for a semi detached or detached house. Any dormer window on the roof slope facing a road usually needs to be set back from the original eaves, and materials used should match the existing house.

If your roof extension goes beyond these volume limits, sits forward of the front elevation, or the highest part of the roof would be taller than the existing roof, you will need to apply for full planning permission instead. Homes in a conservation area, such as parts of the old village around Ealing Road and Eastcote Lane, may face tighter controls on visible roof changes, even where permitted development would otherwise apply. It is always worth checking with the council or a qualified loft company before assuming permitted development covers your project, since roof shape, plot position and any past extensions can all affect what is allowed.

Article Notes

Northolt Village Green, the conservation area covering the historic centre of the town around St Mary the Virgin church and the village green, does not currently have an Article 4 Direction in place. This means that within this conservation area, permitted development rights for loft conversions generally still apply, alongside the usual conservation area design checks on anything visible from the street. Ealing Council does have an Article 4 Direction covering most of the borough, made in October 2024, but this one only removes permitted development rights for changing a house into a small House in Multiple Occupation. It has nothing to do with loft conversions or roof extensions. For homeowners in Northolt looking to convert a loft, the borough wide direction does not add any extra restriction. As always, it is sensible to check your specific address on the council's planning pages, since boundaries and rules can be reviewed and updated over time.

Types of Houses

Northolt is largely a product of interwar suburban growth. The bulk of the housing stock is 1930s semi detached houses, many built with pitched roofs that suit hip to gable loft conversions well. Around Northolt Park, large postwar council estates were built from 1951 onwards, including blocks of flats alongside houses, following the compulsory purchase of the old Northolt Park estate. Closer to the historic village green, you will find a smaller pocket of older buildings, including some surviving cottages, though most pre nineteenth century farmhouses in the area were demolished decades ago to make way for housing. More recently, the Grand Union Village development brought newer homes and a marina near the canal. This mix of 1930s semis, postwar estates and small newer developments means loft conversion projects in Northolt often involve fairly standard roof structures, though older council built properties can sometimes need extra structural checks.
