Kitchen Extensions Hendon

In Hendon a kitchen extension starts with whether you own a house or a flat. The VOA list puts 62% of Hendon homes in flats and 38% in houses, and only a house carries householder permitted development rights. Semi-detached and detached houses, 24% of homes, have the width for a rear or wraparound kitchen; the 13% that are terraces take a straight rear box, or a side return where there is a back addition. We build the structure, bring the steel into the back wall, lay the new drainage and fit the kitchen in one programme.

In Hendon, 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 Hendon: 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 a Hendon semi and a Hendon terrace each take

A Hendon semi can take a rear kitchen that turns the corner into the side passage, while a terrace takes a plain box across the back or a side return. The VOA figures put semi-detached and detached houses at 24% of local homes and terraced houses at 13%, so among houses the wider plot is the commoner starting point. On a semi the side passage can hold the gas meter, the soil stack or a gully, and those need relocating before any wall rises.

A terrace side return runs along the boundary, so the new wall sits on or beside the line you share with next door. That brings the neighbour's gutter, their downpipe and the shared wall into the design, and the Party Wall Act into the timetable: the building owner serves the notices, not the builder. On either house type the corner where the old rear wall meets the new side wall is where the steel works hardest, and it sets how much open floor the kitchen can use.

Housing in Hendon

Hendon has about 16,060 homes on the Council Tax list: 20% pre-1919, 37% interwar and 43% post-war, with flats making up 62% and houses 38%. Most homes here are flats, and only a ground floor flat in Hendon with its own garden can extend its kitchen.

Depth and height limits before a Hendon kitchen needs planning

Without a planning application a single-storey rear extension on a house can project three metres beyond the original rear wall, or four metres on a detached house, in Hendon as anywhere else in England. Prior approval, outside designated land, raises those depths to six and eight metres. The height ceiling under these rules is four metres. Measure from the original rear wall, not from any earlier addition, because a previous owner's utility room already counts against the allowance.

Height matters for a kitchen because of roof lights. A flat roof with a lantern, or a shallow mono pitch with glazing along the top edge, has to stay under the overall ceiling set by the rules, and a lower eaves limit applies close to the boundary. The roof still needs a usable ceiling line and a fall for rainwater. Your designer settles those levels on the drawings; we then build to the depth and height the consent or the permitted development check allows.

The Burroughs and Church End: where Hendon loses the easy route

Two parts of old Hendon, The Burroughs and Church End, lose part of the permitted development route. Hendon The Burroughs Conservation Area and Hendon Church End Conservation Area were both designated by Barnet Council on 27 July 1983. On designated land every side extension needs householder planning permission, so the side leg of a wraparound needs an application in either area, and the larger rear extension allowed through prior approval is not available there at all.

The Burroughs goes further for a small group of houses. Barnet's Article 4 direction there covers 1-8 Burroughs Gardens and 63-77 (odd) The Burroughs, and it removes permitted development rights for enlarging, improving or altering the house and for other roof alterations. If your address is on that list, even a modest rear kitchen needs a planning application. We price from the approved drawings and plan the programme around the date the permission lands.

Ground floor flats in Hendon's mansion blocks and conversions

A ground floor flat in Hendon has no householder permitted development rights, so any kitchen extension off a flat needs a full planning application. It also needs the freeholder's written consent under the lease, because the external walls normally stay with the freeholder and the garden may be demised to you or held in common; the lease says which. Hendon's housing includes interwar mansion blocks, and in a block the managing agent will want method statements before anyone opens up the external wall.

Drainage is the practical difference in a flat. The kitchen sink moves outward, but the stack it joins often serves the flats above, and a new connection into shared pipework affects every household on it. Where the extension sits over or near a shared sewer, the water company's build-over consent comes first. We survey the run early, agree the connection point with the agent, and book any break in the stack for a short, notified window so the flats above are not left without drainage.

• Utility rooms and larders at the back of the extension
• Airbrick ducts to keep existing timber floors ventilated
• Island units with power and waste run through the slab

Trusted Kitchen Extensions in Hendon

We run a Hendon kitchen extension as one job from the groundworks to the worktops. The structural engineer we appoint designs the steel, building control inspects the foundations, drainage and structure, and our own team carries on straight into first fix, plastering and the kitchen installation. You deal with one contact and one programme, and the kitchen units arrive when the room is dry and ready rather than waiting on a separate fitter's diary. Our founder, who has spent his working life on the tools, decides how the trades follow one another.

• Honest updates if a date or a detail has to move
• Kitchen layout agreed before the foundations, so the services land in the right place
• New floor level matched to the existing house, with no step at the opening
