Almost every kitchen enquiry we take in Shepherd’s Bush starts from the same condition: a small original kitchen at the back of a bay-fronted or flat-fronted Victorian terrace, often tucked into a closet-wing return, with a narrow side-return alley running down beside it. The project is rarely a single clean box on the garden. It is a two-move geometry — infilling the side-return to capture that dead alley, and adding a modest rear projection beyond the original back wall — so the cramped kitchen and the dark back room merge into one wide kitchen-diner that opens to the garden. The value is in how those two moves combine into a single room, and the plan has to be worked from the family use backwards, not from the maximum footprint forwards.
Making that one room means removing the original rear wall, and usually the flank of the closet-wing return as well, which leaves an L-shaped opening rather than a simple straight one. That is why a goalpost or portal frame, rather than a single lintel, is so often the answer here: posts carry load down through pad foundations while the beams take the masonry, floors and the rear parapet above. On these narrow terraced plots the remaining walls also lose lateral restraint as the opening widens, and the engineer has to give that restraint back through the new frame. Deflection, not just strength, becomes the binding limit, because the wide sliding or bifold doors the room is built around will bind at the head if the beam above them sags even a few millimetres.
The second constraint is where the water goes out. Pushing the kitchen back and out moves the sink, dishwasher and washing machine away from the existing soil stack at the old rear wall, and waste pipes need a consistent fall to run properly. A long, shallow run across a new slab is exactly where these kitchens go wrong: the floor build-up wanted for insulation and underfloor heating competes for the same few centimetres of depth the gradient needs, and a level threshold out to the garden — usually the whole point of the extension — claims what is left. We fix the wet wall early, keeping the sink and appliances within sensible reach of the drain, and set the build-up, the fall and the threshold detail against one another before the slab is designed rather than after it is poured.
Cooking has to go somewhere, and this is where a Shepherd’s Bush kitchen meets its context. Ducted extract is the effective option, because it removes moisture, grease and odour rather than filtering and recirculating them — but a duct has to terminate somewhere on the outside of the building, and on a terrace that means a grille, cowl or louvre on a rear or flank elevation. Where the house sits within a conservation area, that terminal is a visible alteration to be consented, not a builder’s decision made on site, and where no acceptable position exists a recirculating hood with carbon filters becomes the fallback the layout has to live with. Electrification raises a parallel question: an induction hob, an electric oven and a heat pump between them can outgrow an older incoming supply, so the electrical load is worth checking before the appliance schedule is signed off.
Opening the whole ground floor into one kitchen-diner also changes how the house escapes in a fire, and on a terrace the stair often rises straight out of the room being opened up. Where the kitchen now sits on the route the upstairs bedrooms rely on to reach the front door, building regulations want that answered — commonly through interlinked mains smoke alarms, and sometimes through a protected route or a compliant window to an upstairs room, depending on the storey height and the layout. It is a design decision, not a box ticked at completion, and it is far cheaper to resolve on the plan than to retrofit once the open-plan room the household wanted is built. We set the fire strategy alongside the layout so the openness and the escape both work.
A kitchen-diner is also the hottest room in the house before anyone turns the oven on. Put a glazed rear wall and rooflights on the sunny side and the solar gain arrives on top of the heat the appliances already produce, which is how a handsome new kitchen becomes the room nobody sits in during July, while a north-facing garden asks the opposite question of how to win enough daylight at all. We specify the glass, the shading and the ventilation as part of the design rather than as a remedy afterwards. From there the route is a coordinated one: measure the house, establish which consents actually apply, design the room around its structure, drainage and services, then produce the planning drawings and the building regulations package the application and the builder each need. We say candidly where a scheme looks likely to struggle, and we do not promise approval.
Tenure decides how much of this is even available. Many Shepherd’s Bush houses have been converted into upper and lower flats, and where the kitchen you want to extend sits in a lower or garden flat there are no permitted development rights and the rear garden may be demised or shared, so the lease and the freeholder’s consent have to be established before a layout is drawn. On these flats the acoustic separation to the home above, the waterproofing under the units and the fire separation between dwellings all become part of the brief, and the freeholder’s surveyor reads the drawings as closely as the council does.
