Load-Bearing Wall Removal Greenwich

Safe load-bearing wall removal with steel beam support in Greenwich, propped, sized by the engineer we appoint and signed off by building control.

GS Renovation removes load-bearing walls across Greenwich, in the post-war flats and houses that make up most of the borough as well as the Georgian townhouses near Greenwich Park and the Victorian terraces of Charlton and Eltham. We take out internal walls safely without risking the fabric above.

In Greenwich, 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 Greenwich.

How the job runs

  1. Free site survey at your Greenwich address and an itemised quote.
  2. The engineer we appoint sizes the beam, and the work is registered with the Royal Borough of Greenwich building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
  3. The floor above is propped, the wall comes out and the beam is set on padstones.
  4. Building control inspects the steel before it is covered. We make good, and the completion certificate follows.

Taking out a load-bearing wall in Greenwich

Many of Greenwich's period homes carry solid masonry internal walls that were built to hold up the floors and roof above, so before anything is touched we bring in a structural engineer to establish exactly what each wall supports. In the taller Georgian townhouses off Blackheath and around SE10, a single wall can carry loads from two or three storeys, which changes how the engineer sizes the steel.

Once the engineer has specified the beam, we install temporary props, cut out the masonry in careful stages and lower the RSJ onto padstones bedded into the flanking walls. Every step is planned so the structure is never left unsupported, and in these older properties we watch for lime mortar, timber lintels and past alterations that the calculations must account for before the props ever come down.

Housing in Greenwich

The valuation list shows roughly 125,080 homes in Greenwich, of which 22% are pre-1919, 17% interwar and 60% post-1945, split 55% flats to 45% houses. Since most homes here are flats, a wall in a flat in Greenwich may carry the floors above, so the freeholder agrees first.

Knocking through a Greenwich terrace: the through room on paper

In Greenwich 31% of homes are terraced houses and 13% are semi-detached or detached. In either, the wall between the front and back reception rooms is the classic knock-through, and Royal Greenwich has a name for it. Its building control charges carry a domestic through room as its own item, and its guidance puts a through room first among the examples of simple work that a building notice suits. That gives the owner of a straightforward knock-through a clear order: the design from the structural engineer we appoint, then the notice, then the work.

The route stays simple only while the job does. A through room is one opening in one wall. Add a second opening into the kitchen, take out the chimney breast in the same run, or widen the back wall to the garden, and the job is no longer the single item on the list. Tell building control the whole scope at the start, because the charge and the inspections are set from that description. A job that grows halfway through under a notice written for one opening leaves a gap in the paperwork, and a buyer's solicitor can ask about it years later.

Building control and party walls in SE Greenwich

Removing an internal load-bearing wall is governed by the Building Regulations, not planning permission, so the Royal Borough of Greenwich's building control inspects and signs off the beam and its bearings. The exception is a listed building: there, taking out an internal wall also needs listed building consent before any work starts, because listing protects the inside as well as the outside. Conservation area status on its own does not bring internal steelwork into planning.

Where a supporting wall meets the shared party wall between two terraced or semi-detached homes, common in Charlton, Woolwich and the Victorian streets of Eltham, the Party Wall Act applies and you serve notice on the neighbour as building owner before starting. We give you the engineer's drawings and the programme the notice needs, and run the calculations and the building control application together, so nothing stalls halfway through the job.

Choices that shape the finished opening

Two decisions change the look of a finished opening more than anything else, and both belong to you rather than to the engineer. The first is whether the beam sits below the ceiling as a visible downstand, or is lifted flush into the floor above. Flush is neater and costs more, because the joists then have to be cut and hung off the steel rather than simply resting on top of it.

The second is how much of the wall stays. Leaving a short return at each end, often called a nib, gives the beam a natural bearing and the room a defined edge, and it usually reduces the steel size. Taking the wall out corner to corner looks cleaner but pushes the load further. Both need settling before the engineer designs, because a change of mind afterwards means a new calculation and frequently a new steel. How the ceiling is finished across the beam line is a smaller choice, but it is worth agreeing before the plasterer arrives.

FAQ

Frequently Asked Questions about Load-Bearing Wall Removal Greenwich

Do you charge for a survey before quoting load-bearing wall removal in Greenwich?

A load-bearing wall removal survey in Greenwich costs nothing, and it is part of quoting rather than a service to bill for. GS Renovation allows enough time at SE10 to check the 1950s to 1980s details that move a figure within £2,500 to £6,500 or more per opening (indicative), and to plan the order: the floor above is propped before any masonry is removed. Nothing is owed if you go elsewhere in Greenwich.

Do I need planning permission to remove a load-bearing wall in my Greenwich house?

No. Internal load-bearing wall removal is controlled under the Building Regulations, so the Royal Borough of Greenwich's building control signs it off, not the planning department. Planning comes into play for exterior work within a conservation area, and a listed property needs listed-building consent for internal changes too. We handle the building control application for you.

What might one internal wall be holding up in a tall Greenwich townhouse?

Potentially every floor above. In a Georgian house near Greenwich Park the spine wall often collects joists from the front and back rooms on each storey, and may prop the roof, so loads are traced from the ridge down. Joists landing on the wall are the first clue; another wall standing directly over it upstairs is the second. Either means steel and an inspection.

How is a Greenwich house held up while the wall is taken out?

With temporary works set up before a single brick is cut. Acrow props stand on both sides with spreader boards under their feet and timbers across the ceiling, and strongboys pick up the brickwork above the opening. Over an old suspended timber floor the props need a firm base, so boards are lifted to reach the ground beneath. Nothing is struck until the beam is packed tight.

I own a flat in a Greenwich block: what changes if the wall turns out to be structural?

The paperwork grows before the work does. The VOA counts flats as 55% of Greenwich's 125,080 dwellings, and in a block the lease normally requires the freeholder's written consent for structural change, often after their surveyor has read the engineer's calculations. Removing walls inside a flat also reshapes how you would get out of the bedrooms in a fire, and building control has to accept a written fire strategy for that before propping is booked.

Should the new beam in my Greenwich living room hang below the ceiling or sit within it?

Joist direction and ceiling height decide it. A downstand beam hangs beneath the ceiling with the joists still resting on top, which is simpler. A flush one sits inside the floor depth, so every joist is cut and hung off it on hangers, costing more steel and labour. In a lofty Georgian room off Blackheath a downstand hides near the cornice line; in a lower post-war room it can dominate.

Can a Greenwich knock-through and a chimney breast removal share one building notice?

Yes, one notice can describe both, and it should. Royal Greenwich names a through room and chimney removal among its examples of simple work, and together they can change the design. Where the breast sits in the wall being removed, or beside it, the beam may have to pick up the stack above as well as the floor, and the structural engineer we appoint sizes it for both. If the combined design is involved, full plans lets building control check it before the steel is made.

Does the Progress Estate Article 4 direction stop an internal wall coming out?

Not on its own. The Progress Estate was granted Article 4 Direction status by the Department of the Environment in 1973. An Article 4 direction removes permitted development rights, and works that affect only the inside of a house are not development in planning terms, so the knock-through itself stays a building regulations job. The extras are the risk. Royal Greenwich says there is less permitted development in Article 4 direction areas, so check any new rear door or window before ordering it.

What can a spine wall carry in an interwar Greenwich house?

More than the floor, in some houses. In Greenwich 17% of homes were built between 1919 and 1939. In a house of that period the wall between front and back rooms can carry the first floor joists, a bedroom partition standing on it and sometimes a strut from the roof. We lift a board upstairs and look in the roof space before the engineer designs, because a strut found after the beam is ordered means a new calculation and new steel.
