Wanzhong Food Tower and Offices This office building is sited in an original factory owned by the Shanghai Automotive Industry Corporation (SAIC) and was converted into low-quality office spaces in the 1990s, through subdividing the 7-storeys into 10-storeys. Construction of the Yan’an Highway in the 90s further eroded the easement and green buffers of the site, resulting in an awkwardly oriented tower with undesirable frontage and a lack of public space. The clients were healthcare providers and were keen to bring high-tech, medical and wellness ideas to the building, and to restore the floors to the original heights, thereby privileging the quality of the office spaces over quantity. The new design proposes a public circuit that brings visitors up ramps and steps into the building to common facilities – a restaurant, lounge and display areas, while double height notches were carved both on the interior and exterior to create new social spaces for the workers. A façade comprising vertical greening not only provides strong visual branding for the tower, but also vegetables for the restaurant.
