The disc-shaped HQ building, the world’s first circular skyscraper, was the first building of the Al Raha Beach Project to be completed in the Al Dana area on the Arabian Gulf coast. The building envelope, one of the most complex components to be executed, consists of a 20,000 sqm (215,300 sq ft) unitized glass façade - the main elevations oriented east-west - and 4,000 sqm (43,000 sq ft) of aluminum composite sheet cladding before the diagrid members. Instead, the north-south elevation has a 1,500 sqm (16,100 sq ft) unitized glass façade that yields to a glazed skylight at the top of the building plus 4,400 sqm (47,300 sq ft) of aluminum composite sheet cladding at the perimeter.
110 m / 361 ft
25 stories tall
The circular oval shape of the main building is achieved using triangular façade units - each composed of four triangular glass panes - and irregularly shaped units at the perimeter cladding connection. The size of the façade units varies at each floor (average unit size: 3.6 m wide, 3.8 m high – 11.8x12.4 ft) and this increased the overall complexity of the project. The aluminum composite cladding in front of the diagrid members is also part of the main façade’s unitized system and creates the distinctive diamond-shaped pattern.
30,500 sqm (328,300 sq ft) of unitized glass façade, aluminum composite sheet cladding and glazed skylight.
