Citic Bank Headquarters Diagrid Lattice Inspired By The Chinese Symbol Of Wealth And Stability

Foster and Partners’ headquarters tower for Citic Bank has a prominent location in Hangzhou, on a main axis through a new central business district being constructed next to the Qian Jiang River. The site is also adjacent to one of the city’s most recognizable landmarks – the distinctive golden sphere of the Intercontinental Hotel. The challenge for its design therefore, has been to create a new building that harmonizes with its surroundings, yet has its own integrity and presence and provides an iconic headquarters for the Bank. The design draws inspiration from the elements of traditional Chinese culture – using the symbol of wealth, dignity and stability.

The tower has a striking geometric form – the diagonally-braced façade is pulled inwards to form a symmetrical V-shape across the south-facing elevation. Wrapped in a bronze-colored diagrid lattice, the floor plates widen as the building rises, expanding to provide panoramic views of the river and the surrounding public plaza. The design maximizes the available area within a compact rectilinear footprint, while respecting views of neighboring structures. The tower will provide the highest quality office space – tailored to the current needs of the Bank, but with the flexibility to anticipate future working patterns and demands.

A-frame canopy stretches 72 meters across the ground, in order 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. 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 is naturally ventilated for part of the year, grey water will be recycled and local materials utilized where possible to reduce embodied energy.
