It's easy to see why the spectacular new building at 15 Alice Lane, Sandton, was nicknamed "Dancing Towers” by the team responsible for its design and construction. Its curved silhouette, combined with the striking black and white glass of its façade, make this new Sandton landmark look like it is dancing on the skyline. It's this unique façade – a design first – that makes the team at Aveng Grinaker-LTA Façades proud of their achievement. 15 Alice Lane Towers, designed by Paragon Architects, consists of two curved towers linked by an atrium. Each tower has glazed wings which cantilever 2.5m past their gable ends. "It is a building with a dynamic form," says Croydon Schmidt, managing director of Aveng Grinaker-LTA Façades. The company rose to the challenge of manufacturing and installing a curtain wall to meet the architects' requirement for a glazing effect, using black and white glass, to simulate falling paper.
