THIRD FLOOR THE BUILDING BEFORE REDEVELOPMENT FIRST FLOOR entire façade and pitched roofing, closing in all but one of the indentations in the façade, cladding with a curtain wall concept and introducing a new roof concealed behind the new façade. All existing concrete structural elements remained, the addition of new Bondek slab in-fills allowed for the expansion of the building’s footprint. New steel framing structures allowed for the fixing of the curtain wall system as well as the aluminium cladding. The decision to enclose the existing indentations in the façade had the added benefit of increasing the lettable office area within the building, thus creating more usable office plates. The total GLA was increased to 13,400m 2 which includes the existing retail tenants that remained, and the new corporate tenant area. The modulated curtain wall system includes areas of double glazing and single glazing. The double glazing portions of glass are featured on the prominent façades of the building, on which a random arrangement of vertical, aluminium fins have been applied to achieve a texture to the elevations defined with aluminium clad surrounds. The balance of the façades have a single glazing curtain wall system to create a smooth and sleek look. Furthermore, the façade is articulated with full height aluminium panels as well as plastered and painted brickwork. The subtle application of the black colour has been achieved by way of using a lighter shade of the double glazing to the main elevations and black single glazing to the secondary elevations giving the illusion of shadow. This is complimented by a satin sheen to the aluminium cladding and a textured black Baker Street GROUND FLOOR BASEMENT 1C 35
