CORNERSTONE综合用途建筑，越南 / ROOM+ Design & Build

自18世纪末联排别墅首次出现以来，这种建筑类型逐渐成为主流，与河内和胡志明市等越南大城市不规则且充满活力的道路网完美的契合，同时，由于市中心街区向外并不均衡的城市扩张产生的一些奇形土地难以被利用，也成为了本项目的切入点。

Since its first appearance in late 18th century, townhouse has gradually become the dominant architectural typology which fits snugly into the existing irregular and vibrant networks of streets, roads, and alleys in Vietnamese metropolises such as Hanoi and Ho Chi Minh City. On the other hand, the inconsistent urban expansion of inner-city neighborhoods sometimes results in left-over odd-shaped pieces of land, which are hardly usable.

本项目被打造为一座精美的综合用途建筑，坐落于胡志明市一条繁忙小巷的拐角处，用地为不规则的六边形。任务书要求设计者在首层打造灵活的零售区和停车区，并最大程度地利用上面两层空间。除此之外，本项目对隐私和噪音隔离的要求也很高。设计者是通过融合两种设计方法来实现以上要求的：一种能够敏感响应场地的建筑形式，同时能够为街道测景观产生积极的影响；另一种则是优化空间布局，打造灵活高效的室内空间。

The Cornerstone is a boutique mixed-use building located at a 45 m2 irregular-hexagon-shaped corner site in a busy alleyway in Ho Chi Minh City. The design brief asked for a flexible retail and parking area on the ground level and maximized commercial spaces on the upper two floors. Besides, a high level of privacy and noise insulation from the busy road corner should be ensured. The project brief was fulfilled by two intertwined design approaches: proposing a built-form that sensitively responds to the site while also contribute positively to the streetscape; and optimizing the spatial layouts to accommodate flexible and highly-efficient mixed-use spaces.

首先，建筑严格按照用地不规则的几何形状进行建造，立面上涂油粗糙的灰色油漆，并且随机在三个立面上设置了方形的门窗。设计者还在立面上打造了带有对角栏杆的嵌入式阳台，从这里能够俯瞰小巷的拐角处，这种设计也能够作为有效的设计结局方案，增强隐私和隔音效果，同时还能够接受南向的光照和自然通风。业主还在这些三角状阶梯式的阳台上种满了生机勃勃的绿植，为室内空间和街道侧增添了活力。

Firstly, the architectural built-form strictly responds to the uniquely irregular site geometry. Square-shapes doors and windows are positioned randomly on three faceted facades finished in rough-textured grey-color paint. Recessed balconies with diagonal balustrade walls are proposed on the faceted facade which overlooks the road turnaround as an effective design solution to enhance privacy and noise insulation while also engaging desirable day lighting and natural ventilation from the South-east. These triangular stepping balconies are also provided with lively plantings which add vibrancy to interior spaces as well as the streetscape.

在建筑的内部，三段连续的楼梯整齐地布置在后侧，将三个楼层和屋顶露台连接在一起。浴室、卫生间和储藏室则被布置在楼梯的下方。除此之外，设计者还对主要的功能空间进行了优化设计，在二楼设置了摄影工作室、在顶层设置了精美的办公空间。锯齿状的楼梯间最终呈现为一个1米宽、10米高的空隙空间，因为此处的顶部安装有防紫外线的天窗，该空间能够沐浴在自然光线之下。

Inside, three continuous flights of stair are neatly positioned at the rear edges of the site boundary to connect three floors and the rooftop terrace together. Bathrooms, toilets and storages are comfortably placed underneath those staircases. Therefore, the main functional spaces are optimized and promote a flexible photo studio on the second level and a boutique office space on the top floor. The zig-zagging staircase is designed as a 1-meter wide by 10-meter-high void space, which is amazingly bathed in sunlight thanks to the UV-protected glazing placed on the rooftop.

最后，室内部分选择了较为简洁的材料进行打造，包括抛光混凝土底板、裸露的混凝土天花板、玻璃和彩绘相结合的墙壁。灵活于可用的室内空间与非传统的建筑形式共同组成了这座美妙非凡的建筑，就好像街角的基石一样矗立在这里。

Finally, the interior spaces are finished with a simplistic material palette including polished concrete floors; exposed concrete ceiling in combination with glazing and painted walls. Flexible, ready-to-use interior spaces and the unconventional architectural form all come together to create a subtle yet remarkable building just like an original cornerstone at the road corner.
