Our client commissioned us to design, supply and fit balustrades to three levels of balconies, plus the perimeter of the fourth floor roof. In total the project required over 90 linear metres of balustrades.
We also supplied privacy screens to go between the different flats. There are 27 apartments in total (23 in the main block, plus 4 penthouses on the fourth floor). As you can imagine, this was quite a lot of work for our team – but we love jobs we can get our teeth into! Feel free to click on the images to enlarge them and get a better view of the screens and balustrades.
What do you think of the finished job? We’re really pleased with it, and we hope Merton Road’s new residents love their homes.

We are the appointed structural steel contractor to GPF Lewis, the main contractor refurbishing a building in Mortimer St, W1 (in Mayfair, London’s West End). This is a very complicated job as the main part of the works is a vertical extension forming a new 5th floor level. The 5th floor of the building is currently the roof of the 4th floor!
We have had to strengthen the existing steel frame at critical points of the current roof level in order to take the new structure’s weight… The total weight of steelwork alone is over 60 tonnes! Some of the new cranked roof beams weigh over 2 tonnes, and the only way to get these to the new level is by lifting them with a mobile crane. GPF Lewis arranged for several weekend road closures to set up a 130 tonne mobile crane and lift the new steelwork into place.
The works are ongoing, and we expect to our contract to be complete before December 2021. We will update you with the finished project in the new year! Here are some of our photos and, excitingly, some drone footage taken by GPF Lewis! You can find their write up of the project here.

The staircase needed to span over 9 metres, without support posts. This would normally be achieved by using an off-the-shelf structural steel section such as channel or box section, but in this case the stringer had to look as slim as possible. Furthermore, it could be no wider than the balustrade bolted to it. We achieved the desired specifications by fabricating a hollow box section from 15mm plates, welded together to make a section size of 400mm x 75mm. The plates were fully welded together to give the strength required, and the welds were ground flat to achieve a clean look.
To allow delivery, each stringer was made in two sections and spliced back together on site before erecting. Here is the staircase in our workshop:
Each stringer, once assembled, weighed over 800kgs! We took great care to avoid damaging the finishes. The stringers were erected using Roustabout lifting gear.
The balustrade is bolted directly to the top of each stringer and needed to fit perfectly, so we assembled the stair and made the balustrades on the stringers at our workshop. Then we dismantled it all and sent it to be powder coated by Mulberry and Pier.
Along with a raised floor area and ramp balustrade on the ground floor in the same style, the works were delivered and completed in plenty of time before handover. There was also minimal touching up of the paintwork!

Construction management company Chisholm and Winch employed us to design, supply and fit a steel staircase to the new Thames Barrier control building in south east London. Balfour Beatty. constructed the new Thames Barrier building.
This was a simple stair, except that the half landing had to be radiused on-plan to match the reinforced concrete (RC) frame of the adjacent wall. Following an electronic laser survey of the curved RC wall, we built the stair to fit. Furthermore, Chisholm and Winch needed to ensure that the build up of insulation and plasterboard, applied to the RC, perfectly matched the wall. Bearing this in mind, we trial-built the stair at our works in Shoeburyness, Essex. This allowed us to check that the rolled stringers were a perfect fit to the laser-cut landing plates, and fitted the wall without gaps or clashes.
Once powder coated a rather bright yellow off-site, the stair was delivered and fitted without any issues!
What do you think of the finished product? We’re pleased with it! Although a complex job, our team worked brilliantly to ensure we fulfilled our brief.

LSJ Engineering was commissioned by ACAI Group to work on a commercial property in Harrow, Greater London. The property included a badly corroded external staircase, so our team designed and fitted replacement.
The existing stair, which was probably in excess of 20 years old, did not conform to current regulations. Unfortunately, the replacement stair did not meet regulations either, due to space restrictions. Permission was, therefore, granted by Building Control to replace ‘like for like’ in terms of tread goings and risers.
At the time our in-house drafting facilities were very busy on other projects, so the design work and drawings were carried out by Sam Thewsey of DSD Ltd.
This was an office access stair, so we carried out the removal and replacement over 4 long days, partly over a weekend, to minimise disruption to the businesses.
The new stair stringers, treads and balustrade were hot dip galvanized for durability. We’re pleased with the finished staircase! What do you think of our work?

The challenge on this job was that the stair ran from 7th to 8th floor levels, and the only access was via a 2.5m long lift. This meant that all the stair stringer and balustrade sections had to be less than 2.5m in length! They still required powder coating off site.
Our team designed the stringers to have neat joints. This allowed them to be bolted together once we got them to the correct level. It also ensured the stingers are as strong as if they were on one piece. The half landing support posts formed an ‘X’ to reflect the end client’s logo.
The perforated balustrade panels were bespoke, punched to form neat borders around each balustrade, while the copper handrails were fitted by others.
LSJ also undertook the demolition works to form the stair void opening in the 8th floor slab. We subcontracted to Evolution Enabling of Rayleigh, who installed a crash deck, saw cut and removed the slab, which was equally as challenging as the stair install.
The staircase was to have an industrial look. Our team had an assigned budget and designed the staircase accordingly. We suggested constructing a steel stair and balustrade. We also suggested that it should be powder coated, with a stainless steel, horizontal tensioned, wire infill.

This stair is unusual in that the stair stringers extend to full height to form the balustrades. Handrails are fixed to the inside face. The unique design made installation quite challenging, because the large powder-coated sections had to be manually taken through a double door, then around internal doorways and lifted down to basement level. This all had to be done without damaging the finishes… still, we like a challenge!
The area in which the stair was installed was very tight, so we trial erected the stair in our workshop. When our team did the trial, we discovered a major problem fitting the treads. With the stair destined for such a small space, the problem would have stopped the installation had we not found it. As it was, we changed a few design details, and installation went very smoothly and ahead of programme. We’re very pleased with the finished steel staircase. What do you think of it?

The existing staircase, which was probably over 30 years old, did not conform to current safety regulations. Due to space restrictions, nor could the replacement stair. Building Control granted permission, therefore, to replace ‘like for like’ in terms of tread goings and risers. This can happen with older buildings.
Our new stair stringers and balustrade were powder-coated in an external grade finish before instalment, while the treads were hot dip galvanized rather than powder-coated, for durability.
