Open-Plan Conversions Fulham

GS Renovation creates open-plan spaces across Fulham, turning the divided ground floors of SW6 terraces into knock-throughs, kitchen-diners and broken-plan layouts. Behind each opening is our founder's 30+ years on the tools, and an engineer's calculation for the steel that replaces the wall.

In Fulham, a knock-through finished as one room typically costs £3,000 to £8,000 or more, including the steel beam (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Fulham: the structural engineer we appoint designs the steel, we install it, and building control signs it off.

How the job runs

1. Free site survey at your Fulham address, covering the walls, services and floor levels, and an itemised quote.
2. The engineer we appoint sizes the beam, and the work is registered with Hammersmith and Fulham Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
3. Props in, opening cut, beam on padstones; then floors, heating and electrics are joined up.
4. Building control inspects the steel before it is covered. We finish the room, and the completion certificate follows.

Opening up Fulham's period terraces

SW6's Victorian and Edwardian terraces, whether you own the whole house or a flat within one, were built as small separate rooms, so opening up usually means removing load-bearing masonry between the front and rear receptions or, in a house, into the closet wing. Every knock-through starts with the structural engineer we appoint sizing the steel beams needed to hold the floors and walls above once the dividing masonry is gone.

Whether you want a full kitchen-diner running the depth of the house, a broken-plan layout with a partial return, or Crittall dividers framing the space with glass and steel, the structural principle is the same. Beams bear onto padstones, temporary props hold the load while walls come down in stages, and the steel goes in before the props come out, keeping the work safe in a lived-in Fulham home.

Housing in Fulham

Around 24,310 homes make up Fulham on the valuation list; 76% are flats and 24% houses, and 58% date from before 1919, 4% from between the wars and 39% from after 1945. Where most homes are flats, opening up a flat in Fulham changes the protected route from the bedrooms to the front door, so building control checks the escape before any wall comes out.

Fire strategy first for an open-plan flat in Fulham

76% of homes in Fulham are flats, so an open-plan scheme here is more often a flat than a house. In a flat above ground level the enclosed hall is usually part of the means of escape, and opening the kitchen into it changes how you get out in a fire. That is why building control needs to agree the fire strategy, which may bring interlinked detection, a sprinkler or misting system, or a revised door layout, before any partition is taken down. Changing the plan afterwards means reopening finished walls.

The council's own guidance points the same way. It keeps the Building Notice route for very small works and advises against it for complex building work, and a flat whose escape route is being redesigned is complex. With both routes priced identically, we put the layout, the fire strategy and the engineer's steel through Full Plans together. The approved drawings then go to the freeholder with the licence request, which answers the structural and fire questions a managing agent is likely to ask first.

Regulations and neighbours in SW6

Under the Building Regulations, Hammersmith and Fulham Council's building control inspects the beams and bearings of an SW6 knock-through and issues the certificate; the planning department is not involved. An internal knock-through needs no planning application; planning is a separate question if the outside changes, particularly in a conservation area, and a listed building needs listed building consent for internal work too. We confirm exactly which approvals your SW6 project requires.

A Fulham terrace beam usually bears in a pocket cut into the wall shared with next door, so you serve Party Wall Act notice before any prop goes up. In Fulham, where 76% of homes are flats, a knock-through inside a flat usually also needs the freeholder's licence to alter before the steel is ordered.
