The Site The site is located at the corner of Melville and Ferguson, within the heart of the Northern Illovo’s proposed regional urban node. The spatial planning of the proposed urban development framework for this area promotes the creation of new public urban squares and a series of mixed use developments that are linked by a pedestrian spine that promote a safe and friendly access to mixed use precincts. The site is easily accessible and located within close proximity to the Gautrain station and the Sandton CBD. The site is bordered by Melville on the western side, Ferguson on the south and a residential property on the eastern side. Concept The building was to respond to the site and climatic conditions. Whilst the confined nature of a site measuring 2,478m2 created challenges and limitations, it also offered opportunities for the architects to explore creative ways of turning smaller spaces into generous spaces. The concept for the offices was to create a desirable space that is comfortable and a conducive working environment. This resulted in a cubic design form in response to the small site constraints, with a simple, compact geometric structure, carved in and out to create positive spaces and architectural elements that define the character of the building. Each floor plate offers respective tenants generous access to natural light on each corner end of the building, creating spaces conducive to facilitating creative hubs for exchange of ideas and interaction. was designed and developed by the architects together with the assistance of Sheerline and the façade engineers (Paul Howard from Sheerline & Keith Trowbridge – THS Façade Engineers ). The composite panel is a façade cladding that is made up of an Alcobond and galvalume sandwich panel, with an injected polyurethane foam core and gypsum board as internal final finish glazed into an aluminium façade system. The panels, together with strip windows, form the composition of the façade, creating a mix of solid and transparent vertical lines transforming a low-rise building and creating the perception of a much taller structure. Since the product was new to the market, it had to be tested by the SABS prior to it being used for construction. The façade system offers a high degree of stability, rigidity and an excellent thermal building skin. Façade The façade system was the first of its kind in South Africa, where the building envelope is enclosed with an Alcobond composite panel system which 35 Ferguson 61
