Staircase for WeWork Finsbury Pavement, London

LSJ was commissioned by LTB Ltd to construct a staircase for the WeWork building in Finsbury Pavement, London.

  • Client: LTB
  • Structural detailing by: Sam Thewsey of Draft SD
  • Job Date: early 2018

One of several staircases we have supplied for LTB, who have the contract to refit offices for WeWork.

A common design feature for this client is the slim steel treads infilled with their timber flooring.

We carried out the full design with minimal information to begin with. As we have got to know the client well, however, and understand their requirements, we were confident we could produce some initial designs we could develop.

The void for the stair, which started at basement and finished at first floor had to be formed. We also designed and erected the steelwork that supported the floors once cut.

What do you think of the finished staircase?

Horatio’s Garden, Stoke Mandeville Hospital

LSJ was commissioned a new build for Horatio’s Garden at Stoke Mandeville Hospital in 2018.

  • Client: Boom Construction
  • Structural detail by: Mark Ebbs
  • Job Duration: February 2018-September 2018

We were asked to design, supply and fit an unusual structure by Boom Construction for a charity funded garden at Stoke Mandeville Hospital. The structure was formed by steel plate ‘wings’ supported on columns but also restrained by torsion rods. These wings were then clad with timber and had window support frames suspended from the ends to create the illusion of a floating structure. The design process was quite complicated, but thanks to our state-of-the-art drawing software, we were able to model the structure and have the sections CNC laser cut for accuracy. The sections had to be welded together at our works, we therefore had to make bespoke transportation frames because of the unusual shape. Due to the difficulty of accessing the work area, we erected the frame using a Spiering mobile tower crane from City Lifting, and used temporary supports to prop the structure up until the torsion rods could be installed and tightened.

Architectural Handrails for Harrow School

LSJ was commissioned by T&B to construct unusual architectural handrails for Harrow School in London.

  • Client: T&B
  • Structural detail by: Mark Ebbs
  • Job Duration: May 2019-October 2019

We were commissioned by T&B contractors to supply and fit some railings and an interesting balustrade at Harrow School.

The balustrade guarded a drop over a retaining wall, which cranked and sloped, making the fabrication quite tricky, but the really interesting feature is the infill panels. The panels were formed by CNC punching in aluminium sheet to create an image of long grass stalks. The image was copied from photographs which had been sent to the supplier by the project designers.

The handrails, balustrade frames and infill panels were powder coated in an external grade finish prior to install. What do you think of the finished effect? We really like the image of the long grass stalks in the panels!

Steel Staircase, Great Sutton St, London

LSJ Engineering was commissioned by Area to construct a steel staircase in Great Sutton St, London. 

  • Client: Area
  • Structural detail by: Mark Ebbs
  • Job Duration: August 2019-March 2020

We were commissioned by Area Shop fitters to design and supply and fit a feature staircase to a commercial building in Farringdon, EC1.

Our team worked with the architects and designers to create the look they were hoping to achieve, to make the stair look like it’s made from reinforced concrete. To achieve this we had ‘saw toothed’ stringers laser cut by Pegasus Profiles and strengthened them with PFC sections.

To ensure all components were a good fit, especially the balustrades, we erected the stair in our workshop and build the balustrades directly onto the treads before welding.

The balustrade, which is designed to take a horizontal load of 1.5kN, had been shot blasted and powder coated by Mulberry and Pier for longevity.

We think the finished stair is pretty good! What do you think of it?

Wood & Glass Staircase, London

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

  • Structural detail by: Mark Ebbs

A client who we have worked for on a commercial basis 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, and to conform to current building regs, which with some stretching and squeezing we managed to do.

The simple but striking design we settled on allowed plenty of light into the building, having 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 giving a nice contrast to the light walls.

Fire Escape, Woodside, London

Our team was commissioned by T&B to construct an external fire escape in Woodside, London.

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

T&B Contractors 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. While needing to be a functional, the stair had to be visually pleasing too! Working to the architect’s designs, we designed the stair to fulfil both criteria. The stringers and balustrades were powder coated off site, and the Durbar treads were left in a galvanized finish for contrast.

We think the finished product looks pretty good! What do you think of it?

Staircase for WeWork, Merchant Square, London

In 2015, we were commissioned by LTB Ltd to construct a staircase for the WeWork building in Merchant Square, London.

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

We were asked to design, supply and fit a single story feature stair in an existing building for LTB, who have the contract to refit offices for WeWork. The stair ran from level 6 to 7 in an otherwise occupied building, the only access to the work areas was via a small service lift, meaning all stair parts and void support steel work had to be a maximum of 3m long. The stair was designed with extra splice joints in the stringers, not something we would normally do, but in this instance WeWork were happy to see these joints, and even asked us to highlight them by leaving the connection bolts unpainted.The other unusual feature of this stair was that the half landing was supported from hanging rods from the steel beams over rather than on posts below.

Staircase in Sarah Bonnell School, London

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

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

This staircase is an unusual design. There is one large support stringer running 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 fitted exactly with no gaps. To achieve this, we built the stair completely in our workshop and dismantled it to transport to site and erect. As 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 damage to the finished article. The site-sprayed finish was carried out by Mulberry and Pier.

We think the finished staircase is pretty impressive! What do you think if it?

Office Building for Legalease, Fleet St, London

We were commissioned by Leaglease to add lift shafts, stairs and an extra floor to their building in Fleet St, London.

  • 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 becoming increasingly common to extend upwards rather than sideways, and our project in Fleet St was a far from unique one apart from the location and logistics.

We were working directly for the building’s owner rather than through a large construction company so we 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 so we could successfully add another floor to the building.

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

New Build for Capel Manor School, Enfield, London

LSJ Engineering was commissioned by T&B Contractors to to construct a new build for Capel Manor School, Enfield.

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

This was a new build structure of around 40 tonnes. That’s fairly lightweight for a building of this size and only a single story. That said, the structure was complicated by having a double pitched roof and being 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, which 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 so with a structure this complex. Again, our drawing software ties this process into the design from the start and we are able to issue very good setting out information to the groundworks contractor.
