Interior design and external alterations, by architects AWW, sought to add value to letting space and bring the 90,600 ft2 building up to date. The updated massive, glazed entrance atrium incorporates feature walls – including inset doors – faced with horizontal panels, alternating in three colours: light and dark brown pre-oxidised, and standard ‘mill finish’ copper. Structural columns are similarly enwrapped with alternating finish copper bands and the copper detailing is even continued into elements of bespoke furniture.
The internal copper cladding had a post-lacquer finish applied to arrest further oxidisation, so retaining the three colours and protecting the surface. This creates a reflective surface, mirroring and enhancing the lightness of the atrium space.
ADDING A STRONG BUILDING IDENTITY
The same horizontal copper panel composition of three surfaces continues past the external glazing to the outside. Here, the building’s entrance has been transformed with new copper-clad canopies to create a strong, easily recognised identity, with minimal work to the existing building envelope.
Externally, the copper has not received a lacquer finish, as AWW explain: ‘We consider copper’s natural surface development outside, reflecting the local environment, to be one of the material’s key attributes. An attractive, gradual weathering and softening of the differentiation between the three copper surfaces on the canopies has already begun – and will continue over time – as we anticipated.’
