RSJ and steel beam installation, load-bearing wall removal, chimney breast removal, structural alterations, open-plan conversions and house extensions across Central and Greater London. Call 07472 424 226.
GS Renovation & Home Improvements are London structural specialists with over 30 years' hands-on experience. Our core work is RSJ and steel beam installation, load-bearing wall removal, chimney breast removal, structural alterations and open-plan conversions, all designed by a structural engineer and signed off by building control. We also deliver house extensions, kitchen and bathroom renovations and full refurbishments, so a single accountable team can take your project from structural work through to the final finishes.

Our flagship service. We install RSJs (rolled steel joists) and structural steel beams to open up London homes, removing load-bearing walls and creating wide, light-filled spaces. Every beam is sized by a structural engineer, propped and installed safely, and signed off by building control.
From a single beam over a knock-through to complex steelwork with columns and padstones, we handle the calculations, the temporary propping, the installation and the Party Wall Act notices, so your home is opened up correctly and certified.

Removing a load-bearing wall transforms how a home works, but it has to be done properly. We start by establishing whether a wall is load-bearing, then a structural engineer sizes the steel beam and the padstones it bears onto. Only then do we prop, remove and install.
We manage the whole process, from survey and calculations to safe demolition, beam installation, building control sign-off and any party wall notices, leaving the opening plastered and finished ready for decoration.

Structural alterations cover far more than removing a wall: new openings in solid masonry, replacement floor joists, underpinning weak foundations and forming supported openings all change how loads travel through a building. We coordinate the engineer, the temporary works and the permanent steel.
Any change to the structure of a home has to be designed, propped and certified properly. We manage the structural engineer's calculations, the safe sequence of works, and the building control inspections that sign the project off.

Removing a redundant chimney breast reclaims valuable space in bedrooms and reception rooms. You cannot simply knock one out and leave the stack above hanging, so we support what remains with steel gallows brackets bolted to the party wall, or a beam where brackets are unsuitable, all designed by a structural engineer.
Because chimney stacks usually sit in the shared party wall of terraces and semis, removal normally needs a Party Wall Act notice as well as building control approval. We handle the calculations, the notices, the flue capping and the making good throughout.

Open up a dark, compartmentalised ground floor into a bright, sociable open-plan kitchen, diner and living space. Most open-plan conversions mean removing a load-bearing wall between two rooms, so a steel beam and building control sign-off are part of the job. We handle the structure and the finish together.
Open-plan is not the only option: broken-plan layouts, part-height walls and Crittall-style glazed dividers keep some separation while opening the space up. We level floors, rework lighting and heating across the new room, and design the layout around how you actually live.

Add valuable living space to your home with our professional house extension services. From single-storey rear extensions to side returns and wrap-around extensions, we build high-quality additions that seamlessly blend with your existing property, with the structural steel and openings handled in-house.
We manage the entire process from planning permission and architectural drawings through to foundations, construction and finishing, delivering extensions that add both space and value to your London home.

RSJ and steel beam installation in London typically costs between £1,500 and £4,000 for a single beam to remove one load-bearing wall, including the structural engineer’s calculations and building control. Larger openings, multiple beams, steel columns or projects needing temporary propping and underpinning cost more. GS Renovation provides a free, itemised quote for every project. Call 07472 424 226.
Removing a load-bearing wall does not normally need planning permission, but it always needs Building Regulations approval, a structural engineer’s calculations and building control sign-off. Where the wall is shared with a neighbour, the Party Wall Act usually applies and notice must be served. GS Renovation manages the engineer, the steelwork, building control and any party wall notices for you.
When a chimney breast is removed on one floor, the stack above must be supported, usually with steel gallows brackets bolted to the party wall, or a steel beam where brackets are unsuitable, all designed by a structural engineer. Because chimney stacks sit in the shared party wall of terraces and semis, a Party Wall Act notice is normally required alongside building control.
An internal open-plan conversion does not normally need planning permission, but removing the load-bearing wall between rooms needs Building Regulations approval, structural engineer calculations and a steel beam signed off by building control. If the wall is shared with a neighbour the Party Wall Act may also apply. GS Renovation handles the whole process end to end.

George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!
