Garden furniture manufacturer Yotrio's 110 metre high office tower is China's first dual façade high-rise with openable windows for natural ventilation. Flexible and partitionable office space as well as an extensive showroom have been created on a gross floor area of approx. 34,000 square metres. Most of the showroom is housed in the 5-storey building, which adjoins the tower on the west side. In terms of urban planning, the Yotrio Tower functions as a gateway on one of the main axes to the city centre of Ningbo. The crystal-like bevelled façade at the north-eastern corner of the building marks the main entrance to the building. The modern, clear image of the user is reflected in the outer appearance of the tower by smooth surfaces and the horizontal façade bands of white glass elements that become narrower as the height of the building increases.
