A kitchen extension in Camden Town is built on one of two kinds of home. 12% of homes here are terraced houses and 1% are semi-detached or detached, so the house version is a terrace job: filling the side return beside the back addition, building out at the rear, or both. 86% of homes are flats, and a ground floor flat can extend only with full planning permission. Either way, Camden's Home Improvements guidance sets the tests the drawings must meet, and we fit the new kitchen inside the same programme.
In Camden Town, 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 Camden Town: 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.

Which kitchen extension suits a Camden Town terrace
On a Camden Town terrace with a back addition, the side return infill is the extension that uses the plot most fully. The narrow strip beside the back addition is often a dark passage, and building across it turns a galley kitchen into a room wide enough for an island or a table. A rear extension across the full width is the other option where the garden allows, and the two can be combined into an L shape.
Camden's Home Improvements guidance asks that a rear extension stays subordinate to the house in location, form, footprint, scale, proportions and detailing. For a terrace that points to a single storey that reads as an addition, a roof kept clear of the first floor windows, and brick and detailing that match the house. We price from the drawings your designer submits, and if the consent changes them we reprice the changed items before work starts.
Housing in Camden Town
Camden Town counts roughly 13,150 homes for Council Tax; 44% are older than 1919, 2% interwar and 54% post-war, with 86% flats and 14% houses. Where most homes are flats, only a ground floor flat in Camden Town with its own garden can extend its kitchen.
Conservation area rules and daylight tests in Camden Town
If your house is inside the Camden Town Conservation Area, the appraisal adopted on 4 October 2007 is used to assess the application, and it says rear extensions will not be acceptable where they would compromise the special character of the area. The application also needs a heritage statement describing the significance of what is affected. That puts the design weight on the rear elevation: wall height, brick, roof edge and glazing pattern are all read against the back of the terrace.
Camden also expects a rear extension to pass the 45 degree and 25 degree tests in its Amenity guidance, or to show BRE compliance through a daylight test. On a tight terrace those tests often fix the height of the wall on the boundary and how far the kitchen can project past the neighbour's window. Building on or against the party wall also brings in the Party Wall Act, and you as the building owner serve the notices. We then build to the exact heights on the approved drawings.
Side returns, permitted development and Camden Town flats
A side return infill in a conservation area needs householder planning permission, because Camden's guidance confirms that houses in conservation areas have no permitted development rights for side extensions or two storey extensions. Outside a conservation area, the national permitted development limit for a single storey rear extension on a terraced house is three metres beyond the original rear wall, with a height cap of four metres. These rights can be withdrawn by a direction or by a planning condition on the house, so your designer checks the address and its planning history before relying on them.
With 86% of homes in Camden Town being flats, many ground floor owners ask whether they can extend at all. Householder permitted development applies to houses only, not to flats or maisonettes, so a ground floor flat extension always needs a planning application. Camden also says a leaseholder must have the freeholder's consent and must make a full plans building control application rather than a building notice. We plan the programme around both before any groundworks are booked, and agree the route for materials through the flat at the start.
Roof lights, green roofs and the Camden Town kitchen fit-out
Roof lights on a Camden Town kitchen extension go where Camden's guidance allows, not simply where the light is wanted. The Home Improvements guidance asks that roof lights on a ground floor extension sit away from the building line or use obscure glass, to avoid excessive light spilling into the rooms above and next door. That decides where the roof light goes over the worktop, and whether the flat roof carries one long lantern or two smaller units.
The same guidance prefers a biodiverse green roof with a substrate depth of 100mm on a rear extension, rather than a sedum mat. That changes the structure, because the roof deck and the steel under it carry a saturated growing layer, and the outlet and upstand details must suit it. Below ground, a shared drain under the new floor is usually a public sewer, and building over it needs the water company's agreement. We build the roof, drainage and kitchen fit-out as one programme.

FAQ
Frequently Asked Questions about Kitchen Extensions Camden Town
What is included in your kitchen extensions price in Camden Town?
A GS Renovation price for kitchen extensions in Camden Town includes everything needed to finish the work and get it signed off, within £45,000 to £97,500 excluding VAT for a rear kitchen extension of about 30 square metres (indicative). That covers labour, materials, the engineer's design, Part P certification for the new kitchen circuits and a Camden Council building control completion certificate for the extension, and making good. Anything uncertain at the NW1 property is flagged before starting rather than added later.
Does a side return extension in Camden Town need planning permission?
Yes, if the house is in a conservation area. Camden's Home Improvements guidance says houses in conservation areas have no permitted development rights for side extensions or two storey extensions, so a side return infill there goes through a householder application. Outside those areas an infill can fall within the national side extension limits on height and width, but one that also wraps round the rear often does not. Your designer confirms the route before drawings go further.
How far can a rear kitchen extension go on a Camden Town terrace?
Under national permitted development, a single storey rear extension on a terraced house can go three metres beyond the original rear wall, and no higher than four metres. With prior approval, and outside designated land such as a conservation area, the limit rises to six metres. These rights can be withdrawn by a direction or by a planning condition on the house. Camden also expects a reasonably sized garden to be kept, so the depth is often set by the plot rather than the rule.
Can the owner of a ground floor flat in Camden Town extend the kitchen?
Yes, but only with planning permission. Householder permitted development rights apply to houses only, not flats or maisonettes, so every flat extension goes through a full planning application. You also need the freeholder's consent, and Camden then requires a full plans building control application rather than a building notice. We start work once the planning consent and the freeholder's consent are both in writing.
Will the conservation area stop a rear extension in Camden Town?
Not in itself. The Camden Town Conservation Area appraisal says rear extensions will not be acceptable where they would compromise the special character of the area, so the test is the design, not the principle. Camden's guidance asks for an extension subordinate to the house, and the application needs a heritage statement. A low single storey addition in matching brick is the kind of scheme that wording describes.
What daylight tests apply to a kitchen extension next door to a neighbour?
Camden asks rear extensions to comply with the 45 degree and 25 degree tests in its Amenity guidance, or to show BRE compliance through a daylight test. These are drawn from the neighbour's nearest window and they fix the height and depth of your party wall line. Your designer runs them on the drawings, and we build to the heights shown.
Where should the roof lights go on a Camden Town kitchen extension?
Away from the building line, or in obscure glass. Camden's guidance asks for roof lights on ground floor extensions to be placed so they avoid excessive light spillage into the rooms above. On a terrace that usually means setting the glazing towards the garden end of the roof, which also puts the light over the worktop and the dining table.
Does a green roof change how the extension is built?
Yes. A biodiverse green roof carries a deeper, wetter build up than a plain flat roof, so the joists or steel, the deck, the waterproofing and the outlets are all specified for that load. We agree the roof specification with the structural engineer before the frame goes up, so nothing needs strengthening afterwards.
How do you keep a kitchen working during the build?
We set up a temporary kitchen in another room where space allows, with a sink and worktop connection, and keep the existing kitchen running until the new shell is weathertight. The knock through to the old back wall comes late in the programme, which keeps the dusty, open stage short and contained behind sheeting.
