100 Liverpool Street, central to British Lands Broadgate development, is situated at one of the most well connected locations in the capital and boasts a dramatic internal atrium, surrounded by 530,000 sq ft of commercial space.
Sir Robert McAlpine
Working closely with our partners British Land and Sir Robert McAlpine, after a period of consultation, we were employed to carry out the design, manufacture and installation of the unitised atrium, including the ‘drum’ rooflight and supporting structure. As well as crowning the building, we designed and manufacture the arcade and external soffits that sweep out from Liverpool Street station through to Broadgate Circle.
At the heart of the building is a stunning elliptical atrium, spilling light into the floorplates. With the complexity of a retained and modified structure, the co-ordination of the design was key with the intent delivered through a bespoke unitised glazing system.
Adopting an off-site manufacturing process, the pre-glazed panels were delivered and lifted to position onto structural support around the atrium perimeter allowing for a quick installation with the QA processes managed off-site. At roof level the atrium is capped off with a structural steel grid in a dramatic diamond pattern which supports the roof glazing system. This was craned into position in large pre-fabricated sections with the glazing following.
At the arcade level a bespoke, pre-fabricated soffit system was design with removable panels that once installed looks surgical and crisp. This gives a fitting and high class feel to the approach to the main commercial block.
This truly impressive project was London’s first net-zero delivery and quick to be recognised by multiple awards and a BREEAM Outstanding rating. This provides the benchmark for London offices, demonstrating clear strategic thinking in the approach to reuse of the existing building structure.
The clients vision was to turn Broadgate from a 5 day a week operation to a world-class 7 day a week mixed use destination and the redevelopment of 100 Liverpool Street was a central part of this.
