52 Lime Street, AKA ‘The Scalpel’, is a striking 190-metre office tower in the heart of the City of London. A considered addition to the skyline, it works in conversation with neighbouring buildings to complement the overall composition of the ‘City Cluster’ and improve the public realm. Its simple geometric form is reinforced by partially-reflective glass and bright metallic fold lines and a new public plaza activates the base. A sustainable building, 52 Lime Street has achieved BREEAM ‘Excellent’.
