Construction is underway for the sustainable landmark CITIC Bank headquarters tower. Foster + Partners design for the 100 meter high skyscraper in Hangzhou, China intends to establish and iconic presence for the Bank in a prominent location within the new central business district situated adjacent to the Qian Jiang River.
Resonating with elements of traditional Chinese culture, the tower’s form draws inspiration from the shape of the ancient ‘dou’ or ‘ding’ vessel, a traditional symbol of wealth, dignity and stability. The facade of the diagonally-braced structure pulls inwards near the base to form a symmetrical V-shape across the south-facing elevation. Wrapped in a diagrid lattice, the floor plates widen as the tower rises expanding to provide panoramic views of the river and the surrounding public plaza.
At the base of the tower, a 30-metre-high A-frame canopy stretches 72 metres across the ground floor to create a dramatic entrance experience. This leads to the heart of a diamond-shaped central atrium, which rises up through the full height of the 20-storey tower and helps to encourage natural ventilation during the mid-seasons.
Tiered sky-gardens line the perimeter of the upper floors and a generous winter garden with a mezzanine level accommodates VIP club and meeting spaces at the top of the building. The tower will be naturally ventilated for part of the year, grey water will be recycled and local materials utilised where possible to reduce embodied energy.
