Kitchen Extensions Peckham

Peckham's houses are mainly terraces: 22% of homes here are terraced houses and 3% are semi-detached or detached. On a Victorian terrace a kitchen extension means a side return infill or a modest rear addition, with the new kitchen fitted in the same programme. Southwark Council is the planning and building control authority, and its Householder SPD sets out the depth, height and garden limits your designer works to. A flat has no householder permitted development rights, so a flat owner starts from a planning application, as set out below.

In Peckham, 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 Peckham: 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 kitchen extension on a Peckham terrace involves

On a Peckham terrace the extension fills the side return beside the back addition, pushes a short way into the garden, or does both as a wraparound. 36% of homes here were built before 1919, and a house of that age typically has solid brick walls, a timber ground floor and a rear wall that carries the floors above. The plan follows that shape: the side return is enclosed, the old back wall comes out on a steel, and the kitchen runs the full width.

That sequence sets the programme. Foundations and drainage come first, then the steel into the house under a structural engineer's design, then the walls, roof and glazing, and only then the kitchen fit-out. We run all of it as one job, so the worktop template is taken off the finished walls and the units go in against a plastered room that has dried. Keeping it in one set of hands also means the drainage runs and the socket positions are fixed before the floor slab is poured.

Housing in Peckham

Peckham has around 26,680 homes on the Council Tax list: 56% post-war, 2% interwar and 36% predate 1919, with 74% flats and 26% houses. Only a ground floor flat in Peckham with its own garden can extend its kitchen, which matters here because most homes are flats.

Southwark's depth, height and garden limits for rear extensions

Southwark's Householder SPD, which the Cabinet decided to adopt on 07/07/2025, says a terraced or semi-detached home can be extended to the rear by up to 3m in depth with a maximum height of 4m without an application. It also says a rear extension must not take up more than 50% of the total rear garden space. On a short Peckham garden that second test can bite before the depth limit does, so measure the garden as well as the house before the design is fixed.

Nationally, prior approval can raise the single-storey limit to six metres for a house that is not detached, but only outside Article 2(3) designated land, and the neighbours are consulted. A side return infill counts as a side extension: it must be single storey and no wider than half the original house, and on designated land it needs householder planning permission. A wraparound that joins side and rear needs an application. Your designer measures the original rear wall early, because that decides the route, and the drawings we build from follow it.

Extending a house in the Peckham Hill Street Conservation Area

Plan for a planning application if the house sits in the Peckham Hill Street Conservation Area, designated on 18 October 2011 north of the commercial core of Peckham. Southwark's Householder SPD says the no-permission single storey rear extension is not available to homes in a Conservation Area, and any side extension on designated land needs householder permission. The appraisal says full width rear extensions will normally prove unacceptable and extensions should be clearly subservient, so the design starts smaller than the plot allows. It is not the only conservation area in Peckham, so check the map for your street.

Materials follow from the same designation. Southwark's Householder SPD says UPVC will not be permitted in any of the borough's Conservation Areas, even to the rear of a property, so frames for the glazed doors and roof lights are timber or metal. The designer settles the frame material, glazing pattern and roof form with the planning drawings, and we price and order to the approved set. That way nothing is ordered against a scheme that may still change at application.

Drainage, steel, roof lights and the kitchen itself

The hidden cost drivers in a Peckham kitchen extension are the drains and the steel. Victorian terraces often have the soil stack and a shared run of drainage close to the back wall, so the extension footing may sit over or beside it. A CCTV survey before digging tells you whether a pipe needs rerouting and whether a build-over agreement with the water company is needed, so it does not become a surprise mid-dig.

The steel that replaces the old back wall is designed by the structural engineer we appoint and checked by building control. A side return roof is usually a glazed slope or a flat roof with roof lights, and its falls and flashings against the neighbour's wall need care. With the shell weathertight, the electrician, plumber and kitchen fitters follow in order, and the floor finish runs through from the old room into the new one.

Why Peckham Homeowners Choose GS Renovation

We take a Peckham kitchen extension from the dig to the finished kitchen as one programme, so the builder and the kitchen fitter are not waiting on each other. You get a written programme that shows when the steel goes in, when the room is weathertight and when the kitchen is templated. We build to your approved drawings and the structural engineer's design, keep building control informed at each inspection stage, and hand over the completion certificate and test paperwork at the end.

• Kitchen layout agreed before the foundations, so the services land in the right place
• Rooflights set out against the engineer's steel layout
• Free follow-up visit after completion if anything needs attention
