The building is notably entered by a reworked Savoy style Port Cochere. To the east of the boulevard, the original lower brick façades of the sorting office are retained with a bold and arresting riff on traditional curved mansard roofs above which provide the upper residential floors. A new six-storey building to the north shares a central amenity courtyard garden with a series of sweeping curved façades and balconies. Triple basements house a large cinema complex, huge gymnasium and two theatre spaces to compliment the retail and cafés of the ground and mezzanine areas. Workshops adjoining the existing Almeida Theatre can provide convenient back of house / rehearsal areas.

The Grade II listed Post Office fronting Upper Street is one of two new pedestrian routes through to Esther Anne Place - a new flexible public realm and boulevard at the core of the scheme from which many of the commercial functions and residential parts are reached.

The careful adaption and refurbishment of the existing buildings to conserve embodied energy stored in the existing building fabric and improve energy performance, with many existing architectural features salvaged and reused, was a significant step in ensuring a sustainable approach. Ground source energy is used to deliver the heating and cooling requirements, alongside highly efficient heat pumps and a CHP plant for energy needs. The scheme facilitates sustainable living by optimising accessibility to public transport and supporting the co-location of homes, jobs, amenities and services.
