A kitchen extension in Wood Green is shaped by two things: the terraced streets of N22 and the Noel Park estate at their centre. With 34% of homes here terraced houses and only 3% semi-detached or detached, the typical project here is a side return infill or a modest rear addition behind an Edwardian terrace, with the new kitchen fitted in the same programme. On Noel Park the estate design guidance sets its own limits on depth and width, so the site you are on decides the drawing before anything else does.
In Wood Green, 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 Wood Green: 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 additions on Wood Green terraces
On a Wood Green terrace the extension usually fills the narrow side passage beside the back addition, or pushes a short way into the garden, or both as an L shape. The site describes the housing as Edwardian terraces, converted flats and post-war estates, and 67% of homes were built before 1919. That age matters: the rear wall you are opening is solid brick on shallow footings, and the chimney breast in the back room often has to be supported or removed before a wide opening is possible.
Because a terrace has neighbours on both sides, the new wall on the boundary is the first detail to settle. Footings near the neighbour or steel pocketed into the party wall bring in the Party Wall Act, and you as building owner serve the notices. We set out the footing, the party wall line and the drainage run before the kitchen layout is fixed, since a gully or soil stack sitting in the side return can move the sink and the island. Your designer then draws the kitchen around a structure already agreed.
Housing in Wood Green
The Council Tax list puts Wood Green at about 9,700 homes, 62% flats against 38% houses; 67% went up before 1919, 4% between the wars and 29% after 1945. Where most homes are flats, only a ground floor flat in Wood Green with its own garden can extend its kitchen.
The Noel Park estate: three metres and never full width
On the Noel Park estate in Wood Green, the extension has to follow the estate's own design guidance. It says rear extensions should not be built across the full width of the plot and should not usually extend more than three metres beyond the rear wall. The appraisal describes the estate as a planned estate of approximately 2000 terraced properties. Those matching backs are what the guidance is written around.
Noel Park is a conservation area and also carries an Article 4 Direction, confirmed on 17 December 2020 and in effect from 21 December 2020. In a Haringey conservation area any side extension needs planning permission, so a side return infill here always goes through an application. In practice the kitchen on a Noel Park house is a narrower, shallower room than a neighbour outside the estate could build. The gain comes from the layout instead: a galley run along the party wall, a roof light over the worktop and a wide opening into the middle room. The owner or their designer applies for the planning permission; we build to the approved drawings.
How deep a Wood Green extension can go outside conservation areas
Away from conservation areas and listed buildings, Haringey says a single-storey rear extension on a terraced or semi-detached house may be built without planning permission to 3m, or to 6m through the prior approval route, in which neighbours are consulted. On a detached house the figures are 4m and 8m. Those are the headline depths for a Wood Green terrace outside Noel Park and any other conservation area. The height is capped at four metres, and the drawings still need to satisfy every other condition in the rules before the footings are dug.
For the bigger extension Haringey weighs up, among other tests, whether it would reduce the garden to an unreasonably small size. On a short Wood Green plot that test bites quickly, so a deep single-storey kitchen that leaves a yard of a few paces is harder to justify than a shallower one with a proper garden beyond it. We price both depths so you can see what the extra metres cost in steel, roof and glazing before your designer commits to one.
Flats, drains and the steel into the back of the house
A flat has no householder permitted development rights, because those extension rules apply to houses only and not to flats and maisonettes. With 62% of homes in Wood Green being flats, the ground floor flat in a converted terrace is a real starting point here. There the extension needs planning permission and normally the freeholder's consent as well, since the garden and the rear wall are usually not yours alone to change, and the upper flat may have rights over both.
Drainage is the other early check. Haringey building control says that where development is within 3 metres of a public sewer, you must obtain build over permission from Thames Water before starting work, and on a terrace the shared run often crosses the back gardens. The structural engineer we appoint sizes the steel that carries the rear wall over the new opening, and we sequence the drainage, the steel and the roof so the glazing goes in on a dry, finished frame.
- Cooker hood extraction ducted through the roof or flank wall
- Drain diversions and build over agreements with the water company
- Soil stack and gully rerouting beneath the new floor

The GS Renovation Difference in Wood Green
We run the extension and the kitchen as one programme, so the drainage, steel, roof and glazing are set out around the units you have chosen rather than adjusted afterwards. Before work starts you get a written sequence showing when the back of the house opens, when the temporary kitchen is set up and when the new one is fitted. The structural engineer we appoint and building control are booked into that sequence, and our founder's long hands-on building career sits behind the way each stage is planned.
- Building control and Part P certificates handed over together at the end
- Waste cleared as we go, not left piled up outside
- New floor level matched to the existing house, with no step at the opening

FAQ
Frequently Asked Questions about Kitchen Extensions Wood Green
What happens to the kitchen extensions price if the scope changes in Wood Green?
The kitchen extensions price in Wood Green moves visibly when the scope changes, because the quotation is itemised within £45,000 to £97,500 excluding VAT for a rear kitchen extension of about 30 square metres (indicative). A change at N22 is priced against the same lines rather than renegotiated, and any change touching the approvals, such as the planning route, permitted development or an application to Haringey Council, and a Haringey Council building control foundation inspection, is flagged. GS Renovation issues a written variation and waits for approval.
Does a kitchen extension on the Noel Park estate in Wood Green need planning permission?
Usually, yes. Noel Park is a conservation area with an Article 4 Direction in effect since 21 December 2020. In a Haringey conservation area any side extension, including a side return infill, needs planning permission. So does any single-storey rear extension more than 3 metres beyond the back wall. The estate guidance also asks that rear extensions do not cover the full plot width. The owner or their designer makes the application, and we build to the approved plans.
Can a ground floor flat in Wood Green add a kitchen extension?
Yes, but only with planning permission, because householder permitted development rules for extensions apply to houses only and not to flats and maisonettes. You will normally also need the freeholder's written consent under your lease, and often agreement from the upper flat if the garden or rear wall is shared. We can price from the drawings while those consents are being sought.
How far can a rear kitchen extension go on a Wood Green terrace outside a conservation area?
Haringey says a single-storey rear extension on a terraced or semi-detached house may go to 3m without planning permission, and up to 6m through the prior approval route, provided the house is outside conservation areas and is not listed. For the larger extension Haringey looks at, among other things, whether the remaining garden would be unreasonably small.
What if a public sewer runs behind your Wood Green house?
You need build over permission from Thames Water before work starts, because Haringey building control says this applies wherever development is within 3 metres of a public sewer. On a terrace the shared run often passes under the back gardens, so we check the manhole positions at survey and allow for any diversion or protection in the programme.
How soon can building work start after Haringey building control has been notified?
Work can start on site 48 hours, or 2 working days, after notice of your intention to start has been given, under either a building notice or a full plans application. We give that notice to fit the date the skip and scaffold arrive, so the first inspection lines up with the footings rather than holding the programme up.
Can the kitchen stay in use while a Wood Green extension is built?
For the bulk of the job, yes. The old kitchen usually keeps working until the rear wall comes out, which happens once the new shell is weathertight. At that point we set up a temporary sink and cooker in another room and aim to keep the gap between losing the old kitchen and using the new one as short as the programme allows.
Is a roof light or a glazed rear wall better for a Wood Green terrace kitchen?
On a narrow terrace a roof light over the worktop or along the party wall usually brings more useful light than a wider glazed rear wall, because the middle room is the dark part of the house. Where the estate guidance limits depth and width, the roof glazing is the part of the design that does the most work.
Who supplies the kitchen units in a Wood Green extension?
Either way works. You can buy the units yourself and we fit them in the same programme, or we price the kitchen with the build. The point is to fix the layout early, so the waste, gas, water and electrical positions are set before the floor goes down and nothing has to be moved once the plaster is dry.
