Benzhe设计事务所在上海一个住宅区的阳台上设计了一座小型木结构建筑，名为“知己之舍”，又因其建造位置也被称为“夹缝中的建筑”。该建筑面积仅有19㎡，建筑师将其巧妙地设计在阳台上两个相邻墙体之间的空间中。该项目的业主是建筑师的好友，其要求是在一个舒适的角落设计一间茶室，将其作为待客、品茶或学习的空间。但是业主所在居住区的室内空间无法满足这些功能要求，因此，建筑师决定利用外部空间。新建茶室位于居室的背面，即东北方向，因周围建筑的遮挡影响，该位置仅在早上有两个小时的日照时间。设计团队为了应对限制条件，采用了“不制造，不破坏”的原则，让新建筑去适应周围的环境，而不是去改变或破坏现状。

In a residential neighborhood in Shanghai, amidst a cluster of buildings, Benzhe Design has constructed a small wooden structure built onto an existing balcony. Named Confidant Zhishe or Building in the Cracks, this compact addition spans just 19 square meters and neatly fits into the space between the two adjacent walls of the building. The client, a good friend of the architect, wished for a cozy nook – a tea study – to serve as a space for friendship, tea tasting, and reading. However, the indoor space wasn’t sufficient for these functions, so the decision was made to utilize the external space to expand the usable area. Situated at the rear of the building, in the north-east direction, the new structure receives only about two hours of morning sunlight, as the surrounding buildings block the sun for the rest of the day. Thus, to tackle this challenge, the design team introduces the principle of ‘no making, no breaking’, allowing the project to adapt to its surroundings.

该建筑平面形状为梯形，其北侧是连接室内外的景观平台，西南侧为品茶区，东南角设计有天井，都很好地丰富了建筑空间。该建筑外观像是一个玻璃盒子外面套一层木质板，在保持室内空间视野开阔的前提下还能适当地保护使用者的隐私。这种类似双层表皮的设计手法可以使外观有明显的虚实对比。该建筑的木质表皮为热改性木材，建筑师将其折叠成多边形，并使其尖角巧妙地融入到周边的建筑中。这种不规则的木质几何形状与周围混凝土材质形成了鲜明对比，使建筑表现出一种独特的美感。

Benzhe Design’s layout unfolds as a trapezoidal design, with a landscape platform connecting the indoor and outdoor spaces on the northern side, a tea-tasting area on the south-western side, and a patio space in the south-eastern corner. This space is enclosed within a glass box, enhanced by a wooden envelope to ensure privacy for its occupants. This dual-layered approach creates a stark contrast between the robust exterior and the inviting interior. The addition itself takes the form of a folded polygon crafted from Thermo-modified wood, with its sharp corners cleverly integrated into the building’s perimeter. This irregular wooden geometry introduces an engaging contrast to the otherwise concrete surroundings, imbuing the structure with a unique aesthetic.



建筑屋顶上有圆形开口，东部立面上有拱形窗户，均为建筑特色，因开口形状和阳光之间的巧妙结合，使得内部空间有着丰富的光影效果。建筑立面上也巧妙结合了热改性木材表皮和超透明玻璃两种材质。建筑内部采用棕色木地板，与建筑外观保持一致性。建筑地板结构高于阳台，不仅可以防潮和防水，还利于后续建筑的拆卸和功能的改变。面对充满限制的外部设计条件，建筑师仍然可以设计出符合业主要求的茶室，使其沐浴在夏季清晨的柔和阳光中，营造一种宁静祥和的氛围。

The top and eastern sides of the polygon feature circular openings and arched windows that control the entry of sunlight, creating a dynamic interplay of light and shadow in the interior. The building’s external facade harmoniously combines black Thermo-modified wood with ultra-clear glass. Inside, brown Thermo-modified wood flooring contributes to a straightforward and unified design. The entire structure is elevated above the trapezoidal balcony, providing protection against moisture and water damage and enabling potential disassembly and reuse. In the early hours of a summer morning, the building receives a gentle touch of sunlight, providing a serene atmosphere. This design aims to offer a calm and peaceful space, even in the face of the challenging external environment.
