功能需求
本次改造的房东希望与BWAO一起使用现有的单元。一层前半部分与院子为BWAO使用的办公空间，一层后半部分为房东的居住空间，二层为大家共同使用的开放性活动空间。

​

改造设计
改造单元面宽6.6米，进深18米。室内前半部为通高空间，后半部为两层空间，中间由楼梯联系。改造保留了现有的楼梯结构以及后半部分的楼板，并将楼板延伸到前半部分，形成完整的二层。

​

一层前半部结合楼板中间立柱，布置了面向四周功能的服务型吧台，工作、会议、展览等功能围绕吧台依次展开。吧台一侧集中布置书架、服务台面等功能，另一侧为1.2米宽x3.4米长的主台面，为现浇混凝土一次成型。一层后半部分的房东居住区与前半部分通过推拉门隔开，有单独出入口。

​

二层为开敞的多功能活动空间，吊灯成矩阵排列，既解决通高空间照明问题，又形成新的吊顶界面。朝向花园侧的飘窗与通风开启扇为立面唯一改动。

Renovation
The unit is 6.6m in width and 18m in depth. The front part is a double height space while the back part has a second floor that is connected through a staricase. The design not only keeps the current structure, but rather extend the second floor into the front part, achieving a sweeping second floor space.

The middle columns of the new floor structure is concealed by putting a service bar in the center. Programs such as working, meeting and exhibition are spread out from the bar area. The bar is integreated with a bookshelf, a service area, and a giant countertop that is 1.2mx3.4m in dimension and cast with concrete. The residential part of the first floor has an independent entrance and is seperated from the office part with a sliding door.

The second floor level is an open space for activities to happen. The hanging lights are arranged in a matrix that provide lighting for the space and delineating a new ceiling level at the same time. The protuded window and its ventilation flaps are the only changeds to the main facade.
