Alice Lane Phase I
The first phase of the Alice Lane Development, a building designed to accommodate two tenants, Marsh and Standard Bank, received a 4-star Green Star SA Office V1 Design rating from the Green Building Council SA. This achievement is due to the careful consideration systems and materials including passive heating and cooling systems, double glazing and performance glass, careful selection of materials, water recycling, and green parking bays.
Phase I within the Alice Lane Precinct formed the last important piece of an urban puzzle. Well-located on Alice Lane, the structure sits alongside Phase II and Phase III, surrounding a green lung in Sandton, the financial hub of Africa. The volumes of the building needed to terminate views on the piazza design by creating a defined edge without impacting the piazza’s relationship with the sky and surrounding views.
There are three innovative elements which clearly define the knuckle structure of this building – the west structure, the east structure and the junction. The arrangement of these components challenged the engineer’s resolution of the project, giving rise to the naming of the structures as the Appaloosa North American horse type (west structure); the Kaimanawa (New Zealand) horse type (east structure); and the junction between them as the saddle beam and yoke beam. This “leaping horse” is a bridge structure that spans 25 metres with three levels of offices above, allowing views through to Bryanston, and spatially linking the piazza to the building.
