around the ramp. A water feature provides some white noise against the traffic and creates a cooling atmosphere. There is also plenty of shade on offer through the planting and two roofs that have been positioned to channel the space up and onto the podium. One of these roofs has been designed to carry an artwork or provide a venue for functions. The podium space has pockets of indigenous planting with seating that can be arranged by the user along with open spaces that have been enabled for public gatherings, artwork and events. Design Components The Old Mutual structure is made up of three main components - the main building on the south and east sides consists of large forms and addresses the city as it faces fast-paced Rivonia Road. For this reason, the façade has been designed to be viewed from a distance with bold, large forms and sweeping curves constructed from a double glazed unitised façade and aluminium cladding. The 54 main building protects and holds the more detailed podium building to the north, which utilises a lower scale, smaller forms and more texture to interact with the public podium at a human scale. Along with the glass and aluminium, the architects used a white and grey honed stone cladding to bring texture into the façade. The podium building is seen as an extension of the public space, with the planting and forms from the podium stepping onto the balcony and roof space above providing much needed garden space for the Old Mutual staff. The atrium space makes up the third component and is held between the main and podium buildings. It links the components of office space together and houses the main arrival experience, spaces to connect staff members and vertical circulation routes. Interior Spaces The Ground floor of the building is conceptualised as public space and has been designed to be an No. 1 Mutual Place
