A kitchen extension in Totteridge is mostly a question about a semi-detached or detached house: 67% of homes here are semi-detached or detached and 16% are terraced. That points to rear and wraparound schemes more than narrow side returns. For a house in the Totteridge Conservation Area, the council's appraisal names properties extended in an unsympathetic manner, reducing the spaces between neighbouring houses, as a negative feature. So the width of the new room, and which side of the house it takes, matter as much as its depth.
In Totteridge, 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 Totteridge: 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.

How far a Totteridge kitchen extension can go without planning permission
A single-storey rear extension on a Totteridge house can go four metres beyond the original rear wall of a detached house, or three metres for any other house, under national permitted development rules. It also cannot exceed four metres in height. Those limits are measured from the original house, so an earlier conservatory or extension already uses part of the allowance. Before any drawing is fixed, find out what the house looked like when first built.
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 Barnet Council, and doing it without consent is a criminal offence.
There is a larger allowance of eight metres for a detached house and six for other houses, but only through prior approval and only outside Article 2(3) designated land, which includes a conservation area. In Totteridge that split decides the paperwork. A house outside the designated land may have the prior approval route open. A house inside it needs the smaller limits or a householder planning application, and your designer should confirm which applies before the steel is priced.
Housing in Totteridge
Take the 3,700 or so homes the valuation list gives Totteridge: 12% flats, 88% houses, 8% from before 1919, 33% interwar and 60% post-war. A detached house in Totteridge can set its kitchen extension where the garden gets the best light, with the drain run the main limit on the footprint, and 38% of homes here are detached.
Side and wraparound extensions near Totteridge Village and the Green
On Article 2(3) designated land every side extension needs householder planning permission, so a wraparound kitchen that turns the corner of a house in the Totteridge Conservation Area is a planning job, not a permitted development job. Barnet's Totteridge appraisal lists properties extended in an unsympathetic manner, reducing the spaces between neighbouring houses, as a negative feature. Your designer should expect the gap to the boundary to be looked at closely and should draw the side element to keep a clear space.
One practical answer near Totteridge Village and Totteridge Green is a scheme that grows backwards rather than sideways. The kitchen gets its width from opening the existing rear rooms into the new space, with the side of the house left alone. Where a side element does go ahead, we build it to the approved drawings exactly, because a small change in width on site can take it outside what was approved and bring an enforcement letter.
Windows, roofing and doors under the Totteridge Article 4 Direction
The Totteridge Article 4 Direction lets Barnet Council control minor works such as external doors, windows and roofing materials, hardstandings, porches and external painting. For a kitchen extension this reaches past the extension itself. New bifold or sliding doors in an existing rear wall, a change of roof covering, or a new paved terrace outside the kitchen can all fall under it, depending on where the house sits. The direction does not stop an extension; it adds a consent step.
We ask for the approved drawings and any conditions before ordering glazing or roof finishes, because frames, tiles and slates come with lead times and are hard to change once delivered. If the consent names a material or a colour, that goes on the order and the delivery note is checked against it. Roof lights, lantern sizes and the finish of any hardstanding for bins or a patio are confirmed in writing before they are built in Totteridge.
Structure, drainage and the kitchen fit-out in one Totteridge programme
The biggest structural step in a Totteridge rear extension is usually the opening into the house. A wide rear wall on a detached house can mean a long span, so the structural engineer we appoint designs the beam and its bearings, and building control inspects them before they are covered. Drainage comes next: the route of existing runs under the new floor decides whether a manhole moves or a run is diverted.
The kitchen itself is best planned before the slab goes down. Waste positions for a sink in an island, the extract route for a hob, and floor heating pipework all need to be set in the floor or the walls at the shell stage. We run the build and the kitchen fit-out as one programme, so the fitters arrive on a finished floor with services already in the right places in your Totteridge house.

FAQ
Frequently Asked Questions about Kitchen Extensions Totteridge
How accurate is a kitchen extensions quote for a Totteridge house?
Accuracy on a kitchen extensions quote in Totteridge comes from surveying, itemising and standing behind the total within £45,000 to £97,500 excluding VAT for a rear kitchen extension of about 30 square metres (indicative). Quoting low to win a job and correcting it later is the commonest complaint about builders. GS Renovation prices in the order the work runs: the kitchen layout is fixed before the slab, so the waste, ducts and island services are cast in the right place. Anything unforeseen is costed before continuing at N20.
Does a kitchen extension in Totteridge need planning permission?
Not always. A single-storey rear extension on a house can go four metres beyond the original rear wall of a detached house, or three metres for other houses, under permitted development. On Article 2(3) designated land such as a conservation area, any side extension needs householder planning permission, so a wraparound there needs an application.
Can a Totteridge flat have a kitchen extension under permitted development?
No. Householder permitted development rules for extensions apply to houses only, not to flats and maisonettes. A ground floor flat that wants a rear kitchen extension needs a planning application, and under most leases the freeholder's consent as well. We build once both are in place.
Why does the Totteridge appraisal matter for the width of an extension?
Barnet's Totteridge appraisal lists properties extended in an unsympathetic manner, reducing the spaces between neighbouring houses, as a negative feature of the conservation area. A scheme that eats into the gap to your side boundary is the kind it describes. For a house in the conservation area, keeping the extension to the rear and leaving the side gap open is the easier case to make in a planning application.
Does the Article 4 Direction affect new kitchen doors in Totteridge?
It can. The Totteridge Article 4 Direction allows Barnet Council to control minor works including external doors, windows, roofing materials, hardstandings and porches. Replacing a rear window with wide glazed doors, or laying a new terrace, may need consent that would otherwise not be required. Check before ordering the frames.
What is the height limit for a single-storey rear extension?
Under permitted development a single-storey rear extension cannot exceed four metres in height. A tall roof lantern or a raised parapet can push a design over that line, so the section drawing should show the highest point measured from ground level before anything is ordered.
Can a detached Totteridge house go further back through prior approval?
Outside Article 2(3) designated land, prior approval raises the single-storey rear limit to eight metres for a detached house and six metres for other houses. Inside the conservation area that route is not available, so the depth has to fit the ordinary limits or go through a planning application.
How long does a rear kitchen extension take to build?
The build time follows the size of the opening, the drainage and the lead time on glazing, so the programme is set after the survey. We give you a written programme with the shell, the steel, the glazing and the kitchen fit-out as separate stages, and we update it if anything found on site changes the order.
Can you fit the kitchen as well as build the extension?
Yes. We plan the kitchen with the shell, so waste, gas, extract and floor heating positions are fixed before the slab and walls are finished. A registered electrician certifies the electrics and an engineer on the Gas Safe Register does any gas work, then the units, worktops and appliances go in on a finished floor.
