Kitchen Extensions Epsom

A kitchen extension in Epsom is mostly a ground floor job on a house, since 65% of homes here are houses and 35% are flats. Where the extension needs planning permission, the council's householder guidance shapes it. A single storey rear extension on a terrace or semi is held to 3.25m, a flat roof over it cannot become a terrace, and a pitched main roof asks for a pitched roof at the back. We build the shell, put the steel into the old rear wall and fit the kitchen in the same programme.

For Epsom, on London-derived ranges 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; Surrey work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Epsom: 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 an Epsom house can take

The house type decides the extension. In Epsom 18% of homes are terraced houses and 42% are semi-detached or detached, so the common starting points are a single storey box behind a terrace, or a rear or wraparound addition on a semi with side space. A terrace gives you one boundary on each side, which pushes the design towards a deeper room with light from above. A semi with a side passage lets the kitchen turn the corner and borrow width from the passage.

The flats are a separate case. A flat has no householder permitted development rights, so any extension of a ground floor flat in Epsom goes through a full planning application, and the freeholder's consent under the lease is normally needed as well. We look at the lease position with you before any drawings are paid for, because a refusal from the freeholder ends the idea before Epsom and Ewell Borough Council ever sees it, whatever the drawings show.

Housing in Epsom

Epsom counts roughly 16,290 homes for Council Tax; 15% are older than 1919, 23% interwar and 60% post-war, with 35% flats and 65% houses. 22% of homes here are semi-detached; a semi in Epsom can take its kitchen extension across the back and round into the side passage, which leaves room for a utility behind the kitchen.

The Epsom guidance on flat roofs and pitched roofs

Epsom and Ewell's householder guidance says a flat roofed single storey rear extension must not give access for balcony or terrace use. That rules out the common request to open a bedroom door onto the new kitchen roof. The roof is designed as a roof: a warm deck with a single ply or felt finish, an upstand at the wall and no guarding, so nobody reads it as outdoor space later.

Where your Epsom house already has a pitched roof, the same guidance expects the rear extension to have a pitched roof too. A lean to against the back wall is the usual answer, and it changes the build. The pitch needs enough height at the eaves for a door head, the rafters bear on a wall plate bolted to the old brickwork, and a lead flashing is chased into the brick joint above it. Roof lights then sit in the slope rather than in a flat lantern.

Side windows and rooflights on an Epsom kitchen

Glazing on the side of an Epsom kitchen extension is guided by distance from the boundary. In single storey side extensions, the borough's guidance asks for side wall windows to be at least 1m from the side boundary and not to overlook neighbouring windows. On a wraparound that often means the long flank goes blank or takes high level glazing, and the light comes from the rear doors and the roof instead.

Rooflights on the front and side elevations should be the flush pattern, set in the same plane as the tiling. For a kitchen that runs down the side of an Epsom semi, a side rooflight is a flush conservation style unit rather than a raised kerb model. That fixes the window supplier and the flashing kit early, and the order goes in with the steel so neither delays the roof.

Why narrow Epsom terraces stay at one storey

On a narrow Epsom terrace, the kitchen extension usually stays single storey. Epsom and Ewell's guidance warns that on narrow width terraced properties a two storey rear extension is often not possible. The reason given is loss of daylight and outlook to the neighbours' main rear ground floor window. A kitchen with a bedroom above is then a hard case on those streets. The budget goes into the ground floor room instead.

That shapes the steelwork. With nothing above the new room, the beam across the old back wall carries the existing rear wall and first floor rather than a new storey. The structural engineer we appoint sizes it. We then prop the wall, cut the opening and set the steel on padstones within a short window, so the rest of the Epsom house stays in use. On a terrace or semi, a padstone cut into the party wall is notifiable work under the Party Wall Act, and you as the building owner serve that notice.
