Kitchen Extensions Tooting

A kitchen extension on a Tooting house usually means a terrace. The area's houses are mainly terraced, with the VOA counting 33% of homes here as terraced houses and only 4% as semi-detached or detached. On those houses the side return and the short rear infill are the shapes that fit. The work joins a new room to an old back wall, carries the house above on steel, reroutes drainage under the new floor and finishes with the kitchen itself. We run it as one programme, with one team from the first skip to the last worktop.

In Tooting, 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 Tooting: 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.

Side returns and rear infills on Tooting terraces

The side return is the extension that suits a Tooting terrace best, because it uses the narrow strip beside the back addition that the house already wastes. Filling it, often with a short rear projection as well, turns a galley kitchen and an outside passage into one wide room. With 33% of homes in the area counted as terraced houses, this is the layout to test first, and the cost is driven by how much of the old flank wall and back wall has to come out.

Where the back addition is short or the plot is on a corner, the choice changes. A wraparound, which fills the side return and runs across the rear, gives the most floor but moves two walls rather than one, so the steel and the temporary propping are larger. Because it combines a side and a rear extension it normally needs planning permission. For the 4% of Tooting homes that are semi-detached or detached, a straight rear extension across the full width is usually simpler because there is no neighbour's wall on both sides to build against.

Housing in Tooting

Roughly 23,930 dwellings sit on the valuation list for Tooting. 38% are houses and 62% flats, and by age 67% predate 1919, 8% are interwar and 24% post-war. Most homes here are flats, and only a ground floor flat in Tooting with its own garden can extend its kitchen.

What Tooting houses can build without planning permission

A single-storey rear kitchen extension on a Tooting house can often go ahead as permitted development, within set limits. Nationally the rear projection is capped at three metres beyond the original rear wall for any house that is not detached, and four metres for a detached one, with a maximum height of four metres. Prior approval raises those limits to six and eight metres, but only outside designated land such as a conservation area, so check whether your street is designated before the design is fixed.

A listed building is the exception: work that affects its character, inside or out, including an extension or taking out a wall or chimney breast, needs listed building consent from Wandsworth Council, and doing it without consent is a criminal offence.

Side extensions are different. On designated land every side extension needs householder planning permission, and a side return infill counts as one, so a Tooting terrace inside a conservation area goes through a householder application. Wandsworth has 46 conservation areas, so check Wandsworth's conservation area map for your street rather than assuming. Wandsworth's Housing SPD, adopted in November 2016, sets out detailed guidance on rear extensions, and your designer should read it before drawing the depth, the height at the boundary and the roof form.

Why a ground floor flat in Tooting needs full permission

A flat in Tooting has no householder permitted development rights, so any kitchen extension to a ground floor flat needs planning permission from the start. The national extension rules apply to houses only, not to flats and maisonettes, and with 62% of Tooting homes counted as flats that includes many split Victorian terraces. Build the programme around a planning decision, and allow for the freeholder's consent under the lease as well, because the rear wall and the garden are often not yours outright.

The build itself is much the same as on a house: a new slab, steel over the opening, a new drainage run and a roof with glazing. What differs is the paperwork around it. The freeholder's licence sets the terms, and where the steel bears on the party wall or the work digs near next door's foundations, the Party Wall etc. Act applies and you, as building owner, serve the notices. We work from the approved drawings and the licence, and keep the flat above weathertight while it stays in use.

Steel, drainage and building control sign off in Tooting

The steel that carries the back of a Tooting terrace over a new kitchen opening is sized by the structural engineer we appoint and checked by building control. Wandsworth's fixed extension charge includes forming an opening into the extension up to 1.5m wide, and a wider structural opening may carry an additional charge. A side return with a wide opening across the old back wall is therefore worth flagging on the application so the fee is right first time.

Wandsworth Building Control asks for the application 48 hours before work starts on site and for notice 24 hours before work commences. We set the start date around that, then book inspections at the foundations, the drainage before it is covered, the steel and the finished work. Old clay drains behind Victorian terraces often run exactly where the new floor goes, so we expose and survey them early rather than find them when the slab is being poured.

• Flat roofs with rooflights or a roof lantern over the kitchen
• Floor levels matched through the old opening
• Utility rooms and larders at the back of the extension
