Kitchen Extensions Teddington

In Teddington a kitchen extension starts with the type of house. The VOA list puts 27% of homes here as terraced houses and 24% as semi-detached or detached, so the choice is often between a side return behind a terrace and a rear or wraparound plan on a semi. Flats make up 49% of homes, and householder permitted development rules do not apply to flats and maisonettes, so any extension from a flat needs planning permission, and normally the landlord's consent under the lease as well. We build to the approved drawings and run the kitchen fit-out inside the same programme.

In Teddington, 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 Teddington: 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 Teddington kitchen extension can reach into the garden

Depth is the first number to settle on a Teddington kitchen extension, and two yardsticks apply. Under national permitted development, a single-storey rear extension can go three metres beyond the original rear wall of a terraced or semi-detached house and four metres on a detached house. Richmond's House Extensions SPD sets its own planning guide: a single storey extension is usually acceptable at up to 3m on a terrace, 3.5m on a semi and 4m on a detached house.

For the kitchen itself, that half metre on a semi can decide whether an island fits with a clear walkway or the table has to sit by the doors. We check the unit layout against the drawings before the foundations are dug, so the depth you have consent for is used by the plan rather than lost to a corridor. If your designer wants to go further than the guide, that is a planning conversation you have before we price the structure.

Housing in Teddington

Teddington has about 11,670 homes on the Council Tax list: 40% pre-1919, 13% interwar and 47% post-war, with flats making up 49% and houses 51%. Terraced houses make up 27% of homes here, and a terrace kitchen extension in Teddington starts in a narrow side return.

Side returns and Victorian infills behind Teddington terraces

A side return infill is the natural kitchen extension for the older Teddington terrace, and 40% of homes here were built before 1919. The narrow passage beside the back addition is roofed over and the old side wall comes out, which turns a galley kitchen into a room wide enough for units on both sides. Where an infill runs deeper than Richmond's usual guidance, the SPD limits the eaves height to 2.2m. An infill wall built on or against the boundary is also work under the Party Wall Act, and the building owner serves the notice.

That eaves limit shapes the roof. A low eaves line on the neighbour's side usually means a roof sloping up towards the house, and the gutter detail has to sit within the height. Taking the side wall out needs steel. Where Richmond is the building control body, its inspection framework lists steel and timber beams as an additional inspection item, so we book that visit before the beams are boxed in. The structural engineer we appoint sizes the steel and the padstones.

Roof lights and glazed roofs where Teddington houses are split into flats

Roof glass is the design choice that needs the most care in Teddington, where 49% of homes are flats and an older house can share a garden wall with a converted neighbour. Richmond's SPD warns against light pollution from excessive roof lights and glazed roofs, especially where a property is subdivided into flats. A fully glazed roof over a kitchen can light up the bedroom windows of the flat above or next door every evening.

In practice that points towards a solid roof with two or three well placed roof lights, or a glazed strip along the house wall, rather than a glass box. We fit blinds or tinted units where the drawings call for them, and we place the brightest light fittings under the solid section where the layout allows. The same thinking helps with summer heat gain, which is the other complaint about all-glass kitchens facing south over a Teddington garden.

The Clarence Road Article 4 and Teddington conservation areas

On a conservation area plot in Teddington the permitted development route is narrower. Richmond lists an Article 4 Direction in conservation area CA22 covering Clarence Road. An Article 4 Direction in Richmond can bring extensions and additions, new doors and windows and other changes under planning control, so ask Richmond what the Clarence Road direction removes before the drawings are fixed. In Richmond conservation areas generally, front and side extensions of one storey or more and two storey rear extensions need planning permission.

For a kitchen this means the side element of a wraparound plan goes through planning on any conservation area plot, because all side extensions on that land need householder permission. New rear doors may also need consent where the direction covers them. We wait for the decision notice and build to its conditions, including any brick, joinery or glazing bar details the officer asks for. Matching bricks for a period rear wall take longer to source, so we order them once the approved drawings are final.

The GS Renovation Difference in Teddington

A kitchen extension is two jobs, the building shell and the kitchen inside it, and delays often come from the gap between them. We run both as one programme, so the drainage runs, the soil pipe position and the electrical first fix are set out for the kitchen layout before the floor slab goes in. You deal with one contact from the first site visit to the final clean, and you get a written quote priced against the approved drawings and the engineer's calculations.

• Old kitchen kept in use until the new shell is weathertight
• Building control and Part P certificates handed over together at the end
• Site left safe and secure at the end of every day
