Zonecheck is being installed at 100 Liverpool Street in London, as part of an ambitious redesign project where the existing, city centre, building will be upcycled into a modern and sustainable, multi-purpose development.
The work reinvigorating the 383,0000 sq ft building started in 2017 and was due to be completed in 2021. The aim of the development is to have high quality yet flexible spaces within a unique and vibrant Broadgate campus environment, with a focus on efficient and sustainable design.
Remodelling to improve urban spaces originally separate structures, 100 Liverpool street and 8-12 Broadgate merged into one and became the UBS office building in the 80s. 30 years later, UBS relocated to a new space and British Land became the custodians of the aging structure. In tandem with other stakeholders, British Land came up with an imaginative and forward thinking approach to upcycling the existing building to accomplish what British Land project manager Charles Horne has called “a major feat of engineering.”
In 2017, the building was stripped back to its structural frame and was remodelled into its dynamic new identity. The building’s heart was also adapted and in its place now sits an elliptic atrium, surrounded by flexible office accommodation. The main atrium then spirals up the building to connect efficient office spaces, planted terraces, restaurant and connects back down to the new retail units sprinkled across the ground floor.
“We always try to work with exciting and innovative building projects that are trying to change the way we look at the built environment. We are passionate about developments that improve sustainability especially buildings that are being reimagined in this way so, our energy and water saving products becomes part of a sustainable and modern building system.”
Sustainability is a core feature of the new 100 Liverpool street. The re-use of the structural frame saved 11,000 tonnes of embodied carbon. The implementation of efficient design, low carbon material as well as sustainable building systems such as Zonecheck will also help the project achieve the expected BREEAM ‘Excellent’ rating and seriously reduce its carbon footprint over the building’s lifecycle.
Responding to evolving urban demands The imaginative redevelopment was also in direct response to the modern and urban demands of the market and local workers. Broadgate is surrounded by the invigorated Spitalfields and new tech hub, Shoreditch, which has changed the context of Broadgate and has pushed the area to redevelop and reimagine multiple developments. 100 Liverpool street is also a stone throw away from Liverpool street, a bus station and the new Cross Rail Station, receiving a huge amount of footfall per day.
The project was considered a high risk endeavour due to the many surrounding building reconstructions and proximity to three transport hubs which contributes to the 35 million people who pass through the ground floor of 100 Liverpool street per year. Risk mitigation, complex stakeholder project management and legal protocols were paramount to get the redesign off the ground safely and ensure its completion by 2020.
Once completed, the modern, multi-purpose building will offer 3 new floors, photovoltaic panels, 90,000 square ft of retail units, 430,000 square ft of office units, cycle storage facilities, flexible working spaces, biodiverse gardens and a panoramic restaurant.
From an ageing 80s structure, the new 100 Liverpool street will be transformed into a world-class, mixed use destination. And demand is high, with 90% of the building already occupied, with the Bank of Montreal, Japanese Bank SMBLE and Storey committing to 289,000 sq. ft of offices, while 13 retail units have been exchanged, and will include Waterstones, Kiehls, Reiss and L’Occitane.
