Renewal-Zone：巴塞尔旧红酒仓库衍化公寓︱建筑立柱引领内部城市

在巴塞尔Lysbüchel 街区，旧Coop葡萄酒窖的巨大柱子正以一种全新独特的方式，讲述着这座建筑的历史。立柱既是现有结构中最醒目的元素，也是设计的重要起点。建筑从仓储更改为居住功能，意味着内部空间尺度更小。立柱以各种别具一格的方式裸露和展示在其中，维持了原有的存在感。在横跨建筑物宽度的公寓中，柱子本身强烈的纪念特性呈现出一种别样的体验；在沿建筑纵向延伸的两条“内部街道”中，它们则次序成列。

立柱因此成为了建筑内部空间布局的原点。既有建筑定义出内部城市，在这个项目中，一座房屋内的城市沿着“内部街道”正在形成。内部的空间体系不仅通向楼梯、公共区域和洗衣区，还为各个年龄层和有着不同生活方式的人们打造出多样化的公寓选择，房型从1室半到7室半不等。居住区域与城市区在夹层交汇，这里的内部街道通往横向的入口大堂，邀请人们通过楼梯和坡道进入房屋。商业空间和咖啡馆位于建筑的地面层，直接面向城市。路网的终点是社区空间和共享屋顶露台。

除了原立柱的设计表现力，对生态可持续性的关注也促进了对已有结构的细致处理。旧结构的重新利用节约了42%的建筑能耗。光伏系统和地下水源热泵则满足了建筑能耗三分之二的需求。

The mighty existing columns of the former Coop wine storage in Basel's Lysbüchel neighborhood tell the story of the building's history in an impressive way. They are the most striking elements of the existing structure and form an important starting point of the design. In order to keep their effect tangible despite the small-scale nature of the new residential use, they are exposed and staged in various ways: In the apartments, which span the width of the building, their bulky monumentality is an experience in itself – whereas in the two 'rues intérieures' (internal streets), that run lengthwise through the building, they appear as a sequence. 

Thus, the columns also form the starting point for the internal organization of the house: the actual urban development is defined by the existing building - but along the 'rues intérieures', a city within the house takes shape. This internal system not only provides access to the stairwells, the communal rooms, and the laundry rooms, they also enable a variety of apartment typologies (1.5 to 7.5 room apartments) for all generations and lifestyles. On the mezzanine floor, the domestic sphere links up with the urban one – here the inner street opens into the transverse entrance halls and invites one into the house via stairs and ramps. The commercial spaces and the café are located at ground level at the heads of the building, directly addressing the city. The network of paths finds its end in the community room and the collective roof terrace.

In addition to the design-defining expressiveness of the existing columns, ecological sustainability also motivates the careful treatment of the existing structure. In this case, 42% of the buildings grey energy was saved by continuing to use the old structure. The photovoltaic system and the groundwater heat pump make the building two-thirds self-sufficient in terms of total energy consumption.
