Web Exclusive: 1 Protea Place in South Africa
by Alfredo Machado
Designed by Paragon Architects, 1 Protea Place is a commercial high rise in Sandton, South Africa. The building is comprised of seven parking levels, five of which are underground, and nine office levels that rise above the visible parking podium. The building’s footprint is composed of two towers enclosing a central atrium, set atop the heavier base of the parking levels. The two towers are linked by bridges spanning atrium space.
At the end of 2008, several companies offered their passenger-transportation solutions for the building, including ThyssenKrupp ELevator, Schindler, Otis, KONE and Mitsubishi. ThyssenKrupp Elevator (SA) (Pty.) Ltd., with the support of ThyssenKrupp Korea, offered an elevator solution taking into consideration the environment and the recovery of energy. WAC Consultants selected ThyssenKrupp Elevator to install six elevators. The technology, quality and assembly of materials, as well as delivery time, were also critical considerations made during the consultancy’s decision process.
The project had a one-and-a-half-year timeframe, which presented challenges for planners Murray & Roberts. However, the building was completed on time.
