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.

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 was sited 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!

We were then asked 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? We’re very pleased with them!

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!

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

We designed and fitted the new staircases in around six weeks from start to finish. 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.

What do you think of the new access staircases? We’re really pleased with how they turned out!

Staircase for WeWork Finsbury Pavement, London

LTB commissioned LSJ Engineering 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

This job, at Finsbury Pavement in London, is one of several staircases we have supplied for LTB. LTB who have the contract to refit offices for office space company WeWork.

A common design feature for this client is 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 the client well, however, and understand their requirements, we were confident we could produce some initial designs for development!

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

We’re really pleased with the finished result! What do you think of the staircase?

Horatio’s Garden, Stoke Mandeville Hospital

Boom Construction commissioned LSJ Engineering to create a new build for Horatio’s Garden at Stoke Mandeville Hospital in Buckinghamshire in 2018. Horatio’s Garden is part of the National Spinal Injuries Centre at the hospital.

  • 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 for a charity-funded garden at Stoke Mandeville Hospital. The structure was formed by steel plate ‘wings,’ supported on columns and restrained by torsion rods. These wings were timber-clad and had window support frames suspended from the ends, creating 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.

We’re really pleased with the final building, and we’re proud to have played a small part in improving patients’ experience at Stoke Mandeville Hospital. What do you think of Horatio’s Garden?

Architectural Handrails for Harrow School

T&B commissioned LSJ Engineering 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, 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 to create an image of long grass stalks! The image of grass stalks was copied from photographs 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 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

Area commissioned LSJ Engineering 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 to design and supply and fit a feature staircase to a commercial building in Farringdon.

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

To ensure all components were a good fit, especially the balustrades, we erected the stair in our workshop. We also built the balustrades directly onto the treads before welding. The balustrade, designed to take a horizontal load of 1.5kN, was 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

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 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, set in a small park. As the venue is used for weddings, our stair needed to be functional but also 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.

Staircase for WeWork, Merchant Square, London

In 2019, LTB Ltd commissioned us 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. LTB has the contract to refit offices for WeWork. The stair runs from level 6 to 7 in an otherwise occupied building. Our 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. This is 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 by hanging rods from the steel beams, 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.
