Case Study: LDP

‘Bigger than 26 football pitches and has the largest trading floor in London.’[3], Evening Standard, 28th June 2019

Plumtree Court, also known as The London Development Project ‘LDP’, situated next to Holborn Viaduct in Farringdon Street, is the new European headquarters for global investment bank Goldman Sachs. This huge and prestigious scheme, nine storeys high, has 78,000m² of state-of-the-art, low-energy office space that is sufficient for nearly 10,000 workers. [1]

The Sachs building has taken over the former historic site of the Fleet Building, a Central Telegraph Office, which handled over 25,000 faxes and Telexes at one time until its closure in 1962. In the years that followed, the site was utilised by BT, remaining operational until around 2006 and later stood derelict before the previous building was demolished in 2014, and the land purchased for Goldman Sachs’s vast HQ.

Nestled in the financial district and next door to the Italian Consulate, LDP features enough usable space for Goldman Sachs to consolidate several other workspaces to house around 6,000 of its employees under one roof,’[2] creating an HQ specifically designed for the investment bankers and their staff.


Within the building, we installed three fire curtain systems, with a variety of integrity ratings. In the dining area, an Vertical FC120E fire curtain was installed, with a bottom bar, side guides and headbox all powder coated in RAL 9010 white. Providing 120-minutes of integrity rating, meaning that it will prevent the passage of fire from the exposed to unexposed face for 120-minutes.

Across a transaction window within the scan room, an FC90E with brushed stainless steel side guides and a bottom bar was installed. This installation required a RAL powder coated headbox in the shade 9010 white alongside the stainless-steel finish of the side guides and bottom bar, which was an important aesthetic finish we were able to accommodate. This curtain allows for a 90-minute integrity rating from fire transition through the fire curtain.

Within the lobby, a smaller FC30E was installed, with a finish that mirrored that across the transaction window, with brushed stainless steel side guides and bottom bar, with a RAL powder coated headbox in shade 9010 white. Similarly, this curtain allows for a 30-minute integrity rating from fire transition from the exposed to the unexposed side of the curtain.

As is visible in the products installed at Plumtree Court, we successfully installed all systems and fully completed the project in line with expected time frames.

We were able to be flexible and work around the needs of an extremely challenging and busy site, resulting in the successful installation of all the fire curtain systems.


In partnership with Multiplex Construction Europe and Kohn Pedersen Fox Associates, we installed Fire Curtain Systems necessary to prevent the spread of fire and smoke through the building, in the event of a fire.

Due to the increased flexibility, and discreet design of the systems, the open-plan layout and high-spec design of the building remain uninterrupted, and spaces were given the necessary compartmentation requirements and ensure protected routes for safe egress were maintained.


Due to the highly secure nature of the building, security at Goldman Sachs was an element of challenge for the contractors on-site. Contractors were required to be inducted and use fingerprints to sign in and out to access the building.

Another challenge was logistics. Due to the busy, narrow roads surrounding LDP, and the required delivery methods, Adexon® faced real logistical challenges to deliver the Fire Curtains to the site.

As is commonly the case across London, contractors and delivery staff were also all required to be FORS (Fleet Operator Recognition Scheme) accredited to ensure ‘exemplary levels of best practice in safety, efficiency, and environmental protection,’[4] which limited the contractors available for the job.

Similarly, goods needed to be palleted in a specific manner to allow for delivery, in specific, precisely timed delivery slots, in which goods arrived on site, and were then craned off flat-bed trucks to allow them to be lifted over the front of the building and brought down into the inner recesses of the site. A specific crane supervisor and lift plans were needed to ensure delivery was safe and efficient, as delays resulted in long queues and deliveries being sent away by the Police to stop blockages on the surrounding roads.
