austrian architect hans hollein has finished a design concept of a 42-storey office tower
in the heart of shenzhen, china. the 'SBF tower' is situated adjacent to the town hall and
shennan avenue, a major road in the business district of futian. rising to an overall height
of 200 m, the building repeats a simple 45 m x 45 m square plan into two different zones:
the 'box levels', which are six identical office floors stacked neatly on top of each other,
and the 'sky garden levels', which are five floors of highly flexible work space. from the exterior,
this distinguishes two different alternating zones: the box levels follow an unbroken facade
line while the sky garden levels have deep setbacks and outreaching cantilevers, overgrown
with live greenery and outdoor terraces. by integrating the concept of vertical gardens into
the architecture, the tower promotes an alternative, more sustainable workstyle.
