项目位于上海市徐汇区靠近上海南站的老旧小区内，小区是上海比较典型的“老破小”，相比一般的老旧小区与周边公共空间的联系，本小区被铁路、河道和城市道路所隔断，无法向外拓展公共空间，只能在内部塑造，本项目所在场地也是内部唯一可被改造的空地。建筑师的参与始于一场公益性活动，之后秉持着公益性的原则参与全程的设计与督造。

The project is situated within an old residential compound in Xuhui District, Shanghai, near Shanghai South Railway Station. This compound exemplifies Shanghai's typical "old, dilapidated, and cramped" housing. Unlike many old neighborhoods that maintain connections with surrounding public spaces, this one is physically severed by railways, a waterway, and urban roads, preventing any expansion of public space outward. Therefore, all public space must be created internally. The project site is the only available vacant land within the compound that can be transformed.The architect’s involvement began with a public welfare initiative and continued throughout the entire design and construction supervision process, consistently guided by the principle of public service.

改造最初提出的设想是“儿童友好”为主题的游戏场，经现场调研发现，小区内供老人使用的公共空间同样缺失：在机动车道和停车位的挤压下，老人只能通过几棵树的庇护外加从家里拿来的旧凳子形成一种“自觉的”公共空间。于是老人和小孩的需求被共同纳入空间规划。相对于小孩，作为照顾者的老人将拥有自己的休息空间，同时也释放小孩的探险天性。

The initial proposal for the renovation was a playground themed around "child-friendliness." However, on-site investigation revealed an equally pressing lack of public spaces for the elderly within the community. Squeezed by vehicle lanes and parking spaces, the elderly have had to rely on the shelter of a few trees and old chairs brought from their homes, creating a kind of "self-initiated public space." This observation inspired us to integrate the needs of both the elderly and children into the spatial planning. While seniors enjoy their own dedicated rest areas as caregivers, children are free to indulge their innate sense of exploration.

场地内有两棵大的雪松，沿东西错开生长。这两棵雪松处于亚健康状态，时不时被砍伐并被试图移除，改造的公共空间希望居民与树建立新的联系，让老树被重视与保护。雪松应该是和小区一起成长，甚至早于小区。最初的社区单元应该就是村庄，一个村庄的公共活动常常围绕一棵古树或一口老井展开，那是居民聚集的场所，是一个村落的精神性所在。通过这两棵与小区一起成长的雪松，社区的公共性和精神性被试图重塑——就像以前再贫瘠的村庄，村里的祠堂或老井旁边都是干干净净的——这两棵雪松可以作为关怀和集体身份的象征。

Within the site stand two large cedar trees, growing staggered along an east-west axis. These cedars are in a sub-healthy state and have periodically faced threats of being cut down or removed. The redesigned public space aims to foster a renewed connection between residents and the trees, emphasizing their value and protection. These cedars likely grew alongside the community, perhaps even predating it. The original form of such a community unit might have been a village, where collective activities often revolved around an ancient tree or an old well—a gathering place and the spiritual heart of the settlement. Through these two cedars, which have grown with the neighborhood, we seek to rekindle the communal spirit and public essence of the community. Just as in the poorest villages of the past, the ancestral hall or the old well were always kept clean and respected, these trees can serve as a living symbol of care and collective identity.

场地在最大化保留现状绿植的情况下，规划面积约310平方米。设计沿着两棵大树展开，利用大树错开的空间，架起一座长桥，桥是通往滑滑梯的通道也是接触大树与自然互动的空间，桥下挂的屋面下形成老人活动空间。

The site, while maximizing the preservation of existing greenery, encompasses a planned area of approximately 310 m². The design unfolds around the two large trees, utilizing the staggered space between them to support a long elevated walkway. This bridge serves both as a passage leading to the slide and as an interactive space for engaging with the trees and nature. Beneath the hanging roof structure suspended from the bridge, an activity area for the elderly is created.

屋面可接触到植物，可被触摸，就像中国传统建筑的品质——人和自然的关系是亲近的。屋面轮廓背向车道然后向北侧展开再下压，把人的视线带向两侧和正面的绿植，同一空间表现了幽暗与宽广。

The roof surface is designed to be within reach of plants and touchable by people, embodying the quality of traditional Chinese architecture—where the relationship with nature and humans is intimate and immediate. The roof contour turns away from the vehicle lane, unfolds toward the north, and then gently slopes downward, guiding the viewer’s gaze toward the greenery on both sides and directly ahead. Within the same space, it conveys both a sense of seclusion and expansiveness.

屋顶下的黑色斜柱让人感知到结构的同时也加强了空间的张力。柱子的基础也是屋面下长凳的基座，实现建筑与家具一体化，家具成为建筑的一部分。长凳两侧各悬挑2.5米，与漂浮的屋面形成同构关系。屋面两侧设置可供居民举办社区活动的台阶式座椅，树下利用剩余的钢材设置了一些独立凳子。

The black slanted columns beneath the roof not only make the structure perceptible but also enhance the spatial tension. The column foundations simultaneously serve as the base for benches under the roof, achieving an integration of architecture and furniture—where furniture becomes part of the building. Each side of the bench cantilevers 2.5 meters, forming a relationship of structural homology with the floating roof. Tiered seating for community events is arranged along both sides of the roof, while standalone stools made from surplus steel are placed beneath the trees.

在项目资金和施工成本有限的情况下，建筑师坚信通过充分的图纸准备和足够的现场沟通，依旧可以实现高品质的落地成果。在与结构工程师的持续沟通合作下，项目实现了结构即建筑的轻型的建筑效果，整体72平方米的投影面积只有1.86平方米的落地面积，极大地释放了有限场地内的地面活动空间。

Despite the project's limited funding and constrained construction budget, the architects firmly believe that thorough drawing preparation and sufficient on-site communication can still lead to high-quality, tangible outcomes.Structurally, we maintained continuous communication and collaboration with the structural engineer to achieve a lightweight architectural effect where structure and architecture are integrated. With a total projected area of 72 m², the ground footprint is only 1.86 m², significantly freeing up ground-level activity space within the limited site.

在材料上，项目使用更容易买到的钢材如工字钢、T型钢、钢筋等。由于拉索太贵，便只在人们能接触到的地方使用两根，其他用钢筋代替。人们能触摸到的位置如屋面和栏板选用的是质感细腻的铝板。户外座椅所使用的木头是精心挑选的二手铁柚木。

In terms of materials, we used readily available steel products such as I-beams, T-beams, and rebar. Tension cables were too expensive, so we only used two in areas accessible to people, replacing the rest with rebar. For touchable surfaces like the roof and railings, we chose finely textured aluminum panels. The wood used for outdoor seating was carefully selected reclaimed ironwood (teak).

在构造上，通过细致的构造设计，工人在现场通过基础的切与焊等工序便都能完成，化腐朽为神奇，比如用水管焊接符合小朋友使用的扶手在转角呈现如飞行器般的效果。

In terms of construction detailing, we adopted meticulous design strategies that allowed on-site workers to complete the assembly using basic techniques such as cutting and welding—transforming ordinary materials into something extraordinary. For example, handrails welded from standard pipes, tailored for children’s use, create a dynamic, aircraft-like effect at the corners.

而这些，不正是老旧小区居民的生活智慧？希望设计贴近真实生活，结构触摸大地，长出社区公共精神。

And aren' t these expressions precisely the living wisdom of residents in old urban neighborhoods? We hope the design stays true to life, touches the earth through its structure, and cultivates the public spirit of the community.
