Notting Hill Gate Acoustic Enclosures & Bin Store

Collins Construction commissioned LSJ Engineering to work on a project at Notting Hill Gate, designing acoustic enclosures and a bin store. Although challenging, we’re pleased with this job…

Client: Collins Construction
Structural detail by: the LSJ team
Job Duration: 2019-2020

The main works were a refurbishment and remodelling of an office and retail space next to Notting Hill Gate station.

The building had two floors added, making it five stories high! A new rooftop air handling plant had to be installed bearing onto the CLT roof decking.

Collins commissioned us to design galvanized steel enclosures that supported, and hid, the plant. Working as a team with Collins, the M&E supplier, the project architect and the acoustic louver cladding contractor, we carried out a full structural design.

Our challenge was supporting the plant enclosures on a timber CLT roof deck. We introduced steel spreader beams that spanned the existing steel structure below the roof deck, then built the structures onto these.

Each enclosure is on a different roof area and level of the building. We used a City Lifting 5 axle Spiering mobile tower crane to reach the different areas, deliver and erect the structures. The structures weighed between 5 and 10 tonnes in total!

Following this, Collins asked us to replace an existing ground floor bin store palisade fence enclosure, using similar details. There was no requirement for acoustic louvers, only visual ones to screen the area, so we supplied and fitted them in powder-coated aluminium. Spreader beams at base level were still required, because the mains services running below the existing concrete slab made digging foundations risky.

Here are some of the plans for the project, plus a stunning rooftop view during construction! What do you think of the finished enclosures?

Access Staircases at Linden Court, Leigh-on-Sea, Essex

Dedman Property Management commissioned LSJ Engineering to replace access staircases for the Linden Court flats in the lovely seaside town of Leigh-on-Sea, Essex. This was quite a local job for us, as we are based just up the road in Shoeburyness!

Client: Dedman Property Management
Modelled by: Mark Ebbs
Job Date: late 2016

Our new stairs needed to be functional, comply to current building regulations and have a minimum life of 30 years. The existing steel-and-concrete staircases were old and very rusty. They did not comply to current regulations and were therefore quite dangerous.

We designed and fitted the new staircases in around six weeks. We fitted the new staircases using a small mobile crane and ‘cherry pickers’ for safe height access. The stairs themselves have a hot dip galvanized finish which, with the correct maintenance, will last for 30 years.

This was a relatively short job, but we’re really pleased with how it turned out! What do you think of the new staircases?

Staircase for WeWork Finsbury Pavement, London

LTB commissioned LSJ Engineering to construct a staircase for the WeWork building in Finsbury Pavement, London. We have done a handful of jobs for LTB and WeWork – here are the others!

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

This job, at Finsbury Pavement in London, is one of several staircases we have supplied for LTB. LTB have the contract to refit offices for office space company WeWork. A common design feature for this client is stairs with slim steel treads, infilled with timber flooring.

We carried out the full design for this staircase with minimal information. As we have got to know our client well, however, and understand their requirements, we were confident we could produce some initial designs for development!

We had to form the void for the stair, which starts at basement and finishes on the first floor. We also designed and erected the steelwork that supported the floors once cut. The work went smoothly and we’re pleased with the finished result! What do you think of the staircase?

Horatio’s Garden, Stoke Mandeville Hospital

In 2018, Boom Construction commissioned us to create a new build for Horatio’s Garden at Stoke Mandeville Hospital. Horatio’s Garden is part of Stoke Mandeville’s National Spinal Injuries Centre in Buckinghamshire. You might recognise Stoke Mandeville as the historical home of the Paralympic Games.

Horatio’s Garden is charity-funded and we don’t often work on hospital sites, so this was unusual for us. Structurally and technically, this job was fascinating… although it was also a challenge!

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

We designed, supplied and fit quite an unusual structure in order to create the new building. Formed by steel plate ‘wings,’ the building is supported on columns and restrained by torsion rods. The wings are timber-clad, with window support frames suspended from the ends. The wings create the illusion of a floating structure! The design process was quite complicated… Thankfully, we have state-of-the-art drawing software which allowed us to model the structure. We then had the sections CNC laser cut for accuracy. Although this was a complex project, we completed it in just eight months.

We really think we achieved our ‘floating structure’ aim despite our design challenges, which is gratifying. We’re also proud to have played a small part in improving patients’ experience at Stoke Mandeville Hospital. What do you think of the finished building and garden?

Architectural Handrails for Harrow School

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

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

Our commission was to supply and fit some railings and an interesting balustrade at Harrow School, one of the most prestigious schools in the UK.

The balustrade guarded a drop over a retaining wall, which cranked and sloped. This made the fabrication quite tricky! The really interesting feature on this job, however, is the infill panels. The panels were formed by CNC punching in aluminium sheet, which created an image of long grass stalks! The project designers sent photographs of grass stalks to the supplier, who copied the image.

The handrails, balustrade frames and infill panels were powder coated in an external grade finish prior to installation. 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

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
Structural detail by: Mark Ebbs
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!
