Second prize in an invited, single-phased competition
The appearance of the multifunctional high-rise tower with areas for hotel and office use is determined by the architectural diversity of its structures, colors, luminosities, and mix. And this palette is also strongly influenced by the railway-rich surroundings, the adjacent glass façades, and the white of the Adambräu. Grey bricks envelop the tower, becoming lighter as it climbs. The cutting back of the lower façade reduces the hardness of the corner to the junction, defines the entrance, and creates an appropriate forecourt while, at the same time, the striking "outcrop" of the Pema Tower frames the adjacent former Adambräu site.
The main loadbearing system of the tower consists of in-situ concrete slabs that span from the solid core towards the façade. This enables both vertical and horizontal loads to be consistently transferred inwards. The north façade, which acts as an external film, enables the tower to cantilever dramatically. By designing such a compact loadbearing core the ATP team created a selection of open, column-free floor plans. On the hotel floors these offer the additional advantage of a circulating passage adjacent to the elevators.
