GS Renovation removes load-bearing walls across Paddington, from the stucco-fronted terraces near Hyde Park to the converted Victorian townhouses of W2. We open up these tall, narrow homes without compromising the masonry above, delivering an engineered steel solution signed off by building control.
In Paddington, a complete single opening typically costs £2,500 to £6,500 or more, including the engineer's calculations, the steel beam, propping and making good (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Paddington.

How the job runs
- Free site survey at your Paddington address and an itemised quote.
- 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.
- The floor above is propped, the wall comes out and the beam is set on padstones.
- Building control inspects the steel before it is covered. We make good, and the completion certificate follows.
Removing a load-bearing wall in Paddington townhouses
Paddington's period stock runs three, four or five storeys, so a wall on the ground floor may be carrying the full weight of the floors and roof above it. Before any work starts we commission a structural engineer to survey the property, confirm what each wall supports and specify the steel beam to suit the loads found in these tall W2 homes.
The beam is calculated as an RSJ or a pair of channels, bearing onto padstones that spread the load into the retained masonry. We install temporary props to take the weight, remove the wall in safe stages, then lift the steel into place. The propping stays until the beam is fully bedded, so the structure is never left unsupported for a moment.
Housing in Paddington
Paddington has about 11,790 homes on the Council Tax list: 47% pre-1919, 11% interwar and 42% post-war, with flats making up 92% and houses 8%. Since most homes here are flats, taking out a wall in a flat in Paddington can affect the floors above, so the freeholder's licence comes first and the engineer we appoint checks what it carries.
Earlier unrecorded wall removals in older Paddington conversions
47% of Paddington homes were built before 1919, which gives a building more than a century in which to be altered. A previous owner of the house, or of your flat, may have taken out a wall on this floor or the one above without approval. Before we price a removal we look for that history, because the new opening has to be designed around what is carrying the building now, not what the original plan shows. Westminster accepts regularisation applications as well as full plans and building notices, which is the usual route for bringing earlier unapproved work into the record alongside the new one.
The certificate at the end matters as much as the opening. Westminster's policy is to issue a completion certificate only once all fees due have been received and all relevant electrical and gas certificates have been supplied. A load-bearing wall in a Paddington flat can carry a radiator run, a gas supply to the hob or a circuit feeding the next room, and moving any of those produces its own certificate. We collect the electrician's certificate and the gas engineer's record as each is done and hand them over at the final inspection, so the completion certificate is not held up after the steel is plastered in.
Building control and party walls in W2
Removing a load-bearing wall inside a Paddington home is governed by the Building Regulations, not planning permission, so Westminster City Council's building control inspects and certifies the work. If the building is listed, listed building consent is also needed for internal alterations, including removing a structural wall, and doing it without consent is a criminal offence. Conservation area status alone does not control internal work. We confirm the designation with Westminster City Council before design starts.
Many of these townhouses share a party wall with the neighbouring property, and where a beam bears into that shared wall the Party Wall Act applies. You serve the notices on adjoining owners as building owner before work begins, or your surveyor does, using the drawings we supply. From appointing the engineer to the completion certificate, one GS Renovation team runs every building stage in your occupied home.
How the house is held up while we work
Temporary propping is the part of the job nobody sees and the part that matters most. In a Paddington townhouse the floor above the wall, and sometimes several floors above that, has to be picked up before a single brick is removed. That is done with adjustable props sitting on load-spreading plates, and where the wall itself has to carry through, with needles passed through holes cut above the line of the new opening.
The propping is designed for the actual loads, not improvised, and it stays in place long after the beam has landed. Load is only transferred to the steel once the padstones have been bedded and the masonry above is packed and pinned, and the mortar needs time to gain strength before the props come out. Rushing that stage is what causes the settlement cracks people blame on the beam. Building control sees the bearings before anything is closed up.

FAQ
Frequently Asked Questions about Load-Bearing Wall Removal Paddington
Are there hidden costs with load-bearing wall removal in Paddington?
Hidden costs on load-bearing wall removal in Paddington come from what the W2 survey cannot see, not from the quotation, which sits within £2,500 to £6,500 or more per opening (indicative). Older property can uncover wiring, timber or drainage, and GS Renovation names what it suspects before starting. Approvals are never a surprise extra: building regulations approval of the beam and its bearings is priced from day one.
Do I need planning permission to remove a load-bearing wall in my Paddington townhouse?
No. Removing an internal load-bearing wall is controlled under the Building Regulations, so Westminster City Council's building control certifies it rather than planning. External changes can need planning permission, particularly to a flat or in a conservation area, and a listed home needs listed building consent for internal work too. We arrange the engineer's design and building control sign-off as part of the work.
Can walls come out in a post-war Paddington block of flats?
Some can, many cannot. 42% of Paddington homes were built after 1945, and blocks of that era often use concrete crosswalls or frames that hold the building up, so a wall that looks like a partition may be structural. The engineer works from the block's drawings or opens up to check, and the lease normally makes any change subject to the freeholder's written consent.
Where do the props go when removing a wall in a converted Paddington townhouse flat?
Sometimes into the flat below. If your floor cannot carry the temporary load, the props have to run down through it to a floor that can, which means access to a neighbour's home. That is agreed in advance, alongside the freeholder's consent. Strongboys and needles are set before any brick is taken out, and the steel is packed tight before the props are struck.
Does opening up my Paddington flat change how I would escape a fire?
It does, which is why building control asks for a fire strategy. Flats are 92% of Paddington's dwellings, and in most the entrance hall doubles as a protected route out. Taking the wall between hall and living room away puts rooms with fire risk on that route. Westminster City Council agrees the approach before the layout is approved, and the design follows.
Can the beam stay clear of the cornice in a tall Paddington reception room?
Often, if the joists allow it to sit inside the floor depth. When they run onto the wall being removed, they can be hung from a flush beam and the cornice returned neatly at the new opening. When they run parallel, a downstand is likely, and the cornice is run around it. Tall period ceilings absorb a downstand better than most, so it is rarely a deal-breaker.
What if a previous owner removed a wall in a Paddington flat without approval?
Westminster accepts regularisation applications for that situation, alongside full plans and building notices. Regularisation asks building control to assess work already done, and the inspector can ask for parts of it to be exposed so the beam and its bearings can be seen. Where we are removing a further wall in the same Paddington flat, it makes sense to regularise the old opening at the same time, because the engineer is already checking the load path through it. Work old enough to predate the regularisation procedure cannot be regularised, and then the engineer's report is the record.
Can a missing gas certificate hold up sign-off of a Paddington wall removal?
Yes. Westminster's policy is to issue the completion certificate only once relevant electrical and gas certificates have been supplied and all fees due received. If a gas pipe ran through the wall and was rerouted, or new circuits replaced the sockets on it, the certificate for that work belongs in the file. Without it the completion certificate waits, and a buyer's solicitor is likely to ask for it when the flat is sold.
Is the brickwork in a pre-1919 Paddington house strong enough to carry a new beam?
Not always at the exact point where the beam lands. 47% of Paddington homes were built before 1919, and walls of that age were laid in soft lime mortar, sometimes with hidden flues or earlier openings behind the plaster. The structural engineer we appoint asks for the wall to be opened at each bearing before designing the padstone, and a bearing that lands on a void or a flue is moved or built up in engineering brick first.
