A gentle pleasant promenade up through the verdant gardens to the piazza brings one to the main entrance. Building Planning The overall scheme comprises in effect two buildings - one the primary building, and the second to be occupied by other tenants in the short-term and to provide expansion space for Webber Wentzel in the long-term. However, both elements are physically connected and offer a seamless unified building identity and spatial form. A strong spine of building sets up against the eastern site boundary with fingers of office wings facing north stretching out across the site. The southern wings form the first phase occupied by Webber Wentzel, enclosing a generous atrium and addressing the prominent corner of the site; the northern wing sits back from the Rivonia Road edge, creating the park element and embracing a secondary entry with a smaller atrium and circulation core, and the courtyard garden. The auditorium and related spill-out area occupies the knuckle between the two phases and the indoor-outdoor relationship here sets up the tone for the easy flow between the building wings. The building footprint is angled to better face north, setting up the slight twist on the site establishing the dynamic of the plan. Regular office footprints turn slightly on each floor making a variety of façades which are further sculpted by stepping in and out to create interest and special features of outdoor terraces. The Atrium The central heart of the building is the generous broad rectangular atrium which creates a dynamic and active zone where staff and visitors can gather, meet, and exchange ideas. The triplevolume entrance forms the entry threshold, given comfortable human scale by the floors 60 90 Rivonia
