Steel Staircase, Great Sutton St, London

In 2019, Area commissioned LSJ Engineering to design, construct and fit a steel staircase to a commercial building in Great Sutton Street, Farringdon. The aesthetic of this staircase is a little different!

Client: Area

Job Duration: August 2019-March 2020

In order to create the aesthetic Area wanted, our team worked with architects and designers. Our brief was to make the stair appear as though it was constructed from reinforced concrete. While a little different from most commissions, this project was satisfying to carry out. We achieved our brief using ‘saw toothed’ stringers, laser cut by Pegasus Profiles. The stringers are strengthened using PFC sections.

To ensure all components were a good fit, especially the balustrades, we initially erected the stair in our workshop. We also built the balustrades directly onto the treads before welding. The balustrade, which was designed to take a horizontal load of 1.5kN, was shot blasted and powder coated by Mulberry and Pier in order to ensure longevity.

Although the design brief was challenging, we think the finished stair is pretty good! What do you think of it?

Wood & Glass Staircase, London

In 2018, a private client commissioned LSJ Engineering to construct a wood-and-glass staircase.

Structural detail by: Mark Ebbs

We had previously worked with this client on a commercial basis. This time, he asked us to design and install a staircase at his home in West London.

The property was quite old and the stairwell ran up three floors. The challenge here was getting the dimensions of the staircase to fit in the existing opening. We also had to conform to current building regulations, which – with some stretching and squeezing – we managed to do!

We settled on a simple but striking design. It allowed plenty of light into the building, with a continuous central laminated glass panel up the centre and solid oak timber treads with open risers to match the flooring throughout the landings.

The steel stringers were powder-coated a very dark grey. This formed a nice contrast to the light walls.

Fire Escape, Woodside, London

T&B Contractors commissioned our team to construct an external fire escape in Woodside, north London. This was a challenging project, because our work needed to be both functional and aesthetically pleasing. It’s not always easy to make fire escapes look pretty!

Client: T&B Contractors
Structural detail by: Draft Structural Detailing
Job Duration: spring 2018-spring 2019

T&B awarded LSJ Engineering the contract to design, supply and erect a feature external fire escape staircase at Woodside in Wood Green, London. The building is a council venue for weddings, and is set in a small park. Our stair, therefore, needed to be functional and visually pleasing! Working to the architect’s designs, we designed the stair to fulfil both criteria. The stringers and balustrades were powder coated off-site, while the Durbar treads were left in a galvanized finish for contrast.

What do you think of our before-and-after photos of the building?

Staircase for WeWork, Merchant Square, London

In 2019, LTB Ltd commissioned us to construct a staircase for the WeWork building in Merchant Square, London. We have undertaken various jobs for LTB and WeWork (LTB has the contract to refit offices for WeWork). You can see the others here if you’re interested!

Client: LTB
Structural detail by: Mark Ebbs and Draft Structural Detailing
Job Duration: May-August 2019

We designed, supplied and fitted a single story feature stair in an existing building for LTB. The stair runs from level 6 to level 7 in an otherwise occupied building. Our only access to the work areas, therefore, was via a small service lift. This meant all stair parts and void support steel work needed to be 3m long, maximum, in order to fit into the building!

We designed the stair with extra splice joints in the stringers. That’s not something we normally do, but in this instance WeWork were happy to see these joints. They even asked us to highlight them by leaving the connection bolts unpainted! The other unusual feature of this stair is that the half landing is supported by hanging rods from the steel beams, rather than on posts below.

Staircase in Sarah Bonnell School, London

In 2015, T&B Contractors commissioned us to construct a staircase with balustrades. This was for Sarah Bonnell School in Stratford, east London.

Client: T&B Contractors
Structural detail by: Mark Ebbs
Job Duration: March 2015-August 2015

This staircase is an unusual design. One large support stringer runs up the centre of the staircase, with steel plate treads on top, cantilevered out each side. As the balustrade follows the shape of the treads and is fixed through them, it was critical that the bottom rail fit with no gaps. To achieve this, we built the stair completely in our workshop and dismantled it to transport it to the school. We erected it on site. Because the sections were so large and heavy, and as we had to site weld some sections together, we chose to spray paint the stair on site to avoid damaging the finished article. Mulberry and Pier carried out the spray painted finish.

What do you think of the finished staircase? We think the before and after photos really show how well it turned out!

Office Building for Legalease, Fleet St, London

Leaglease commissioned our team to add lift shafts, stairs and an extra floor to their building in Fleet Street, City of London, in a substantial structural steel project.

Client: Legalease
Structural detail by: Mark Ebbs & Mick Simpson
Job Duration: 2016-2017 (18 months)

Space to develop in London is rare, so it is increasingly common to extend buildings upwards rather than sideways. Our project in Fleet Street was, therefore, far from unique – apart from the location and logistics.

We worked directly for the building’s owner rather than a large construction company. When we won the contract to build a steel framed single story extension on the roof, we were also asked to work out how to get the steel work up there, and erect it, in order to successfully add another floor to the building.

Our solution was to site a mobile tower crane in Fleet Street over several weekends and carry out the works as quickly as possible. As you can imagine, closing such a busy London thoroughfare is not an easy process! We embarked on considerable traffic management, and arranged bus diversions. We contracted City Lifting who supplied the crane and arranged everything else with the council directly. The team completed the work over three weekends.

What do you think of the photos we took during the project? Not a bad view…

New Build for Capel Manor School, Enfield, London

T&B Contractors commissioned LSJ Engineering to construct a structural steel new build for Capel Manor School in Enfield, north London.

Client: T&B Contractors
Structural detail by: Mark Ebbs
Job Duration: 2016

This was a new build structure of around 40 tonnes. 40 tonnes is fairly lightweight for a building of this size, which is only a single story. That said, a double pitched roof made the structure complicated. It also curved on plan.

Our Tekla 3D modelling and drawing software allows our team to detail structures with great accuracy. We can order curved sections to be made exactly as required from CNC files. This makes fabrication quicker and ensures the final site erection goes very smoothly.

Accurate setting out and installation of the column holding down bolts is critical – especially with a structure this complex! Again, our drawing software ties this process into the design from the start, so we are able to issue very good setting out information to the groundworks contractor.

Here are some of the construction photos! Not a bad view… What do you think of it?

Vertical Extension and Cantilevered Staircase at Cowcross St, London

Stoneforce commissioned the LSJ Engineering team to build a vertical extension in Cowcross Street, London, in 2018. We fitted a cantilevered staircase on the same job.

Client: Stoneforce
Structural detail by: Mark Ebbs
Job Duration: September 2018-January 2020

This was another vertical extension, at Cowcross Street in Farringdon, central London.

We supplied and erected a two story extension, on top of a building already three stories high. The building needed its roof removed to complete the works, so the main contractor put a full scaffold lid on it. This made erecting our frame with a mobile crane very difficult! Thankfully, we were provided with a hoist to get all the steel sections to roof level. We erected the frame using Genie lifts and gantry frames for the heavier sections.

On the same contract, we supplied and fitted an unusual cantilevered staircase from the basement level to ground floor. The stair flight formed continuous 20mm steel plate treads and risers, with non-slip nosing strip slots milled into the treads. The whole stair cantilevered off a concrete wall. To hide the fixing points, a stud wall was built a few inches in front of it, and the treads and risers fully welded together. Because some welding and grinding were involved in the fitting process, the stair was painted on-site.

What do you think of the finished work?
