Open-Plan Conversions Paddington

GS Renovation creates open-plan spaces throughout Paddington, opening up the compartmented rooms of W2's Victorian townhouses into kitchen-diners and broken-plan living. We combine engineered steelwork with careful finishing so these period homes near Hyde Park feel light and connected while staying structurally sound.

In Paddington, 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 Paddington: 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 Paddington 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 Westminster City 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.

Open-plan conversions in Paddington townhouses

Paddington's period homes were built as a run of separate rooms, so opening them up usually means removing one or more walls between the front and rear reception rooms or through to a kitchen. Where those walls are load-bearing, a structural engineer sizes a steel beam on padstones to carry the floors above, and we prop and demolish in safe stages before the steel goes in.

Not every dividing wall is structural; some are later stud partitions that can come out simply. For homeowners who want zones without losing the period feel, we fit broken-plan touches such as Crittall glazed dividers and part-height walls, keeping light flowing through these tall W2 rooms while defining the kitchen, dining and living areas.

Housing in Paddington

The Council Tax list puts Paddington at about 11,790 homes, 92% flats against 8% houses; 47% went up before 1919, 11% between the wars and 42% after 1945. Where most homes are flats, opening up a flat in Paddington changes the protected route from the bedrooms to the front door, so building control checks the escape before any wall comes out.

Why a Paddington open-plan flat goes to full plans

Westminster says a building notice can be used instead of full plans only where the work does not affect the layout of the building and is not affected by the Fire Safety Order (RRO). An open-plan conversion changes the layout by definition, and in a block or converted house the shared stair and landings fall under the Fire Safety Order. So a Paddington open-plan scheme goes in as full plans, with a fire strategy for the new layout drawn alongside the engineer's beam details. Westminster aims to reply to a full plans application within 5 weeks and says it may take longer, and the programme allows for that.

The practical effect is that the design is fixed before the application goes in. With 92% of Paddington homes being flats, the scheme also has to satisfy the freeholder, who may hold the fire risk assessment for the common parts. We draw it once, with the fire strategy, the steel and the new door positions on one set of drawings, so the freeholder's licence to alter and the full plans application describe the same flat. Changing the layout after approval means going back to both, which is the slowest way to finish an open-plan job.

Getting a Paddington knock-through signed off

A knock-through inside a Paddington home is governed by the Building Regulations, so Westminster City Council's building control inspects the beam, the propping and the padstones and issues the completion certificate. This is not a planning matter; internal open-plan work needs no planning permission, exterior alterations to a conservation-area property can require separate consent, and a listed home needs listed building consent for internal work too.

Because these W2 townhouses share a party wall with the neighbour, any beam bearing into that wall makes the work notifiable under the Party Wall Act, and you serve the notices as building owner before starting, using the drawings we supply. One GS Renovation team then appoints the engineer, installs the steel, books the building control sign-off and does the plastering, so you get a finished, certified open-plan space with minimal disruption.

• Rooflights and glazed roofs to bring light deep into the plan
• Structural engineer coordination and building control sign-off
• Heat loss and acoustic considerations before the wall comes out
