A vibrant new destination, that will complement its historic location, deliver exemplary workplace and transform the public realm, including a public viewing gallery at the top of the building.
This mixed-use development invites the public in, to create a vibrant, 24/7 destination for the City that complements and revitalises the historic Leadenhall Market next door.
Flexible, future-proofed workplaces are designed to attract diverse tenants and foster wellness. Features include corner bays to maximise daylight and views, natural ventilation with on-floor plant, green balconies and amenity roof terraces.
Innovative mechanical systems, low-carbon materials and systems designed to last are utilised to reduce the whole life carbon of the project.
