Open-Plan Conversions Holland Park

GS Renovation creates open-plan living throughout Holland Park, turning the compartmented rooms of W11's period houses and flats into kitchen-diners and broken-plan spaces. We knock through safely, install the right steelwork and finish with clean, contemporary lines, including Crittall dividers where wanted.

In Holland Park, 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 Holland Park: 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 Holland Park 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 the Royal Borough of Kensington and Chelsea 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 Holland Park's period homes

The Victorian villas and terraces around Holland Park were built as a series of separate rooms, with a wall between the front reception and the rear, and a closet wing and side return at the back. Homeowners in W11 increasingly want these combined into one bright kitchen-diner. Because the dividing wall is usually load-bearing, a knock-through is structural work, not simply demolition, and every project starts with an engineer.

The engineer sizes a steel beam to carry the floors and masonry that the wall currently supports, bearing onto padstones at each end. We prop the structure, remove the wall in staged sections and lift the beam into place before releasing the supports. For a broken-plan feel that keeps some separation, we can frame a Crittall-style glazed divider so light travels through while the cooking and living zones stay gently defined.

Housing in Holland Park

Count the homes in Holland Park and you get about 4,280: 28% built since 1945, 4% between the wars and 67% before 1919, with flats at 81% and houses at 19%. Most homes here are flats, and opening up a flat in Holland Park changes its fire escape route, which building control checks.

Opening up a Holland Park villa without losing its original plan

The front and back drawing rooms of a Holland Park villa were often designed as a pair, joined by a wide opening or folding doors, and that arrangement is part of the character of the house. Where the villa is listed, the plan form carries the same weight as the cornices. With over 4,000 listed buildings across the borough, by the Royal Borough's own count in its plan review, checking the list entry is the first task on any open-plan brief here. Listing covers the interior, so a knock-through needs listed building consent as well as building control approval.

The way through is to open the space while keeping the plan legible. Leaving short nibs of wall at each side and a downstand at ceiling level lets the two rooms still read as two, and it gives the structural engineer we appoint solid bearings and a place to conceal the steel. Cornices are returned around the nibs rather than cut off, and skirtings follow the same line. The consent drawings show each retained section in elevation, so the officer can see exactly what survives, which is often the point on which an application for a listed interior turns.

Consents and coordination in the Royal Borough

Because the wall being removed often adjoins the party wall shared with the neighbour, or the new beam bears into it, an open-plan conversion in these W11 houses is frequently notifiable under the Party Wall Act. You serve notice on the adjoining owner before work begins, so the legal groundwork is done long before the props go up and the dust sheets come out.

Knocking through internally is governed by the Building Regulations rather than planning, so the Royal Borough of Kensington and Chelsea's building control inspects and signs off the steelwork. Planning permission only becomes relevant if the outside of the building changes, though listed homes need listed building consent for internal work too. We manage the engineer's calculations, the building control inspections and a tidy finish, so your open-plan space is signed off and ready to enjoy.
