这是由Studio Af6完成的集合住宅公共空间改造设计。该项目所需要解决的是两幢90年代建造的三层住宅之间的交通联系问题。这两幢住宅有100个居住单元，却只能通过楼梯和长廊解决交通问题。建筑长约100米，被一条坡道内街所分割。建筑师的设想是置入三个带有电梯的桥梁结构以解决垂直交通问题，同时以固有的走廊来解决水平交通问题。为了尽可能降低建筑预算和未来的维护成本，设计将充分利用现有的建筑及其结构。新置入的结构同时还将解决管道网络等其他问题。该方案的本质是对两个独立建筑物之间的空间进行优化，重新配置内部街道，增建的部分用于交通联系和公共活动空间，以达到提升空间效率的目的。新的垂直交通核心使得每户家庭可以尽可能的减少在走廊穿行的距离，同时为了便于识别，每个核心被赋予不同的色彩。这三个连接体均为钢结构，楼板则采用复合镀锌地板装饰的混凝土板。

The project tackles the problem of accessibility in two three story multifamily residential buildings built in the 90s comprised of 100 public rental units. The only access to the homes was by stairway. The buildings are roughly 100 metres long and are separated by an interior street with a steep incline.The potential architectural intervention in the entire complex made us reconsider the initial approach. Our proposal was to install three bridge structures each containing a lift to resolve the accessibility issues in all the homes using the existing corridors that ran through the buildings lengthwise.The plan was guided by criteria of minimal intervention， incorporating resources provided by the pre-existing architecture. Consequently， new social spaces for the residents were built and installation and future maintenance costs were reduced.The intervention also resolved other problems with the hung plumbing network and the building’s finishes.The approach to mediating between the two separate buildings by reconfiguring the interior street separating them， using materials and building solutions chosen for their simplicity， accessibility conditions were improved and the space， which residents had previously avoided crossing， could now be used for transit and as public space.The new vertical circulation cores provide service to the longitudinal corridors that connect the homes using as few lifts as possible. Each core is a different colour to make it more easily identifiable by users and to define the resulting public spaces.The three bridge structures that contain the lifts are formed by steel porticoes that span the distance between the two buildings. Composite galvanized steel floor decking with reinforced concrete was used for the floor slabs.
