The tower block complex, with vistas to Qingdao’s sandy beach to the south and the Laoshan mountains to the east, accommodates a mixture of office space for a bank, small office units for rent, apartments and retail areas. The apartments are located in the slender, 150 m high east tower while the 100 m high office tower to the west serves as headquarters for a bank, including a customer service hall on the ground floor. The design responds to the multi-faceted briefing for this building complex with a sculptural form which is made cohesive by applying a uniform natural stone cladding over several stories. The office areas are faced with a double-skin facade, with the outer glass level flush with the natural stone cladding and the ventilation gap receding to the interior.
