Kitchen Extensions Ilford

A kitchen extension on an Ilford house is almost always a terrace job: 44% of homes here are terraced houses and only 3% are semi-detached or detached. That means a side return infill or a single-storey rear addition, built tight between two neighbours, with the new kitchen fitted in the same programme. Redbridge Council's Housing Design SPD caps a single-storey rear extension on a terraced house at 3.5m deep, so the drawings start from that figure rather than from a wish list.

In Ilford, a rear kitchen extension of about 30 square metres typically costs £45,000 to £97,500 excluding VAT, or £60,000 to £100,000 for a side return (indicative London ranges, Resi, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Ilford: the structural engineer we appoint designs the foundations and steel, we build the room and fit the kitchen, and a registered electrician certifies the electrics.

What depth and height Redbridge accepts on an Ilford terrace

Redbridge's Housing Design SPD sets the ceiling for depth: 3.5m for a single-storey rear extension on a terraced or semi-detached house, and 4.5m for a detached one. On an Ilford terrace that 3.5m is the number to design the kitchen around. Island, sink run and dining table all have to fit inside it, plus the thickness of the new rear wall. We set out the room on paper at that depth before anyone orders units, so the layout never depends on space the guidance will not give.

Height is controlled too. The same SPD says a flat roof extension should generally be 3m high, with any parapet no taller than 150mm. That shapes how deep the roof build-up can be, which in turn limits how much insulation and how thick a roof light kerb you can fit under the parapet line. On an Ilford rear addition we agree the ceiling height inside with you early, because raising the finished floor or dropping the ceiling is easier to settle on drawings than on site.

Housing in Ilford

Take the 14,670 or so homes the valuation list gives Ilford: 53% flats, 47% houses, 66% from before 1919, 5% interwar and 29% post-war. Since most homes here are flats, only a ground floor flat in Ilford with its own garden can extend its kitchen.

Side returns and wraparounds behind Ilford's Victorian terraces

The site describes Ilford's housing as Victorian and Edwardian terraces and converted flats, and on that terrace plan the side return is the obvious place to gain kitchen width. The narrow strip beside the back addition is infilled, the old side wall comes out on steel, and the kitchen widens across the full plot. Where the back addition is short, the infill often turns the corner into a wraparound that also pushes out at the rear.

Redbridge asks for wraparound and rear projection infill extensions to have low eaves and shallow pitched roofs, with eaves kept to 2.4m above ground level. In an Ilford side return that eaves line runs along the boundary with next door, so it fixes the pitch and where the glazing can sit. A shallow glazed slope along the infill brings light into the middle of the house, which a terrace kitchen otherwise lacks. We detail the gutter at the boundary so the rainwater stays on your side.

Permitted development, planning and the flat question in Ilford

Permitted development only goes so far on an Ilford terrace. National rules let a single-storey rear extension reach three metres beyond the original rear wall of a house that is not detached, and no more than four metres in height. Outside Article 2(3) land, the prior approval route raises that depth to six metres, with the neighbours consulted first. A planning application is judged against the 3.5m in Redbridge's SPD instead. You or your designer choose the route before the steel is ordered, because it fixes the depth you design to.

Flats are different. Householder permitted development rules for extensions apply to houses only, not to flats and maisonettes, and 53% of homes in Ilford are flats. If your kitchen is in a ground floor flat of a converted terrace, any extension needs planning permission, and normally the freeholder's consent under the lease as well. We build to whatever consent is granted, and give your designer the site measurements and existing construction they need to draw it.

Steel, drains and inspections on an Ilford kitchen extension

Opening the back of an Ilford terrace to a new kitchen means a beam across the old rear or side wall. The structural engineer we appoint sizes it. Where Redbridge is your building control body, its booking list includes lintels, beams and RSJs among the inspection types, alongside foundations and excavations, and we call those visits with the steel exposed and the trenches open. Where the steel bears on the party wall, the Party Wall etc. Act applies. You serve the notices as the building owner; Redbridge treats the Act as a civil matter it takes no part in.

Drainage is the other early question. The back of an Ilford terrace can have a shared run serving several houses, so the new sink, dishwasher and any rainwater from the roof light need routing before the slab goes down. We expose the existing runs at the start. A drain shared by more than one property is usually a public sewer, and building over it needs the water company's agreement as well as building control approval, so that is settled before the foundations are dug.

• Utility rooms and larders at the back of the extension
• Island units with power and waste run through the slab
• Floor levels matched through the old opening
