Melbourne based LAB architecture studio have been awarded first prize in an international design competition for the Riyadh business centre complex, Saudi Arabia. The management board of renowned developer alsheikh saleh al-rajhi were looking for a unique design for the business centre on a site of 39,124 m2. LAB’s design is a collection of angled and interlocking singular towers which come together to form a dramatic architectural image. The project aims to provide a diverse selection of office towers while maintaining a coherent and complex ensemble. A gently sloping cut in the ground will become a public promenade providing retail and dining facilities, while also functioning as a place of relaxation. The perforated skins of the facades provide climate control of the buildings, in such a harsh environment.
