青龙湖·漂浮种子：自我更新

Floating seeds of Qinglong Lake:self-renewal

万物在时间里流动，流动的过程形成历史。凝固不语的建筑也在时间里流动，流动的过程形成地方的历史。在其间建筑师们寻找过去与现在的平衡点，交出面对未来的答卷。

All things flow in time, and the process of flow forms history. The frozen architecture also flows in time, and the flowing process forms the history of the site. During this period, architects seek for the balance between the past and the present, and hand over the answer to the future.

梳理analyze

自2018年，成都提出“公园城市”新理念和城市发展新方式以来，成都梳理了城市空间，围绕成都绕城高速周边布局，以绿道为线，78座桥梁为点，串联起整个环城生态公园121个特色园，建起自然资源与市民休闲生活之间的便捷桥梁。

Since 2018, Chengdu "park city" put forward new ideas and new urban development mode, Chengdu rearranged the city space around Chengdu beltway, “Green belt” goes through 78 bridges connecting the entire 121 garden ecological park around the city, which built a convenient bridge between natural resources and citizen leisure life.

位于环城生态公园内的青龙湖·漂浮种子承载科普、研学、体验的空间需求，于此我们取“万物生长循环”为建筑意象，通过提取农田间农作物的生长状态作为设计元素，采用聚碳酸酯板、陶瓦、红砖等常见材料，让建筑呈现出新旧交替、自由流动的场所气息。

Floating seeds of Qinglong Lake where is located in ecological park has space requirements of the experience of the science and research, in which we take the circulation that everything grows as the architectural image. Through the extraction of farm crop growth status as design elements, adopting the common materials such as polycarbonate panels,  ceramic tile, red brick, make construction present a new era, the free flow of breath.

场地梳理，是城市更新项目的核心环节。“留”与“改”如何平衡，是这类场地现状复杂的项目的重点。建筑方面：部分建筑并未受到较大破坏，修缮后可继续使用；部分建筑墙体破损，屋面破烂，屋顶年久失修，部分结构无法满足使用要求；还有一部分建筑墙柱坍塌、墙体倾斜非常严重，存在极大的安全隐患。

Site analysis is the core of urban renewal project. How to balance "maintain" and "renovate" is the focus of this kind of project with complex site situation. Architecture part: Some buildings were not damaged greatly and could continue to be used after repair. Part of the building walls were damaged, roof disrepair, part of the structure cannot meet the use requirements; There are also some columns collapsed, walls tilted are very serious, there is a great potential safety hazard.

景观方面：场地荒废多年，内部杂草丛生，原有梧桐树长势良好；原硬化路面破损严重；围墙将场地与外部农田、公园完全隔离，影响人们参与体验。

Landscape part: the site has been abandoned for years, the interior is overgrown with weeds, the original plane trees grow well; The original hardened road surface is seriously damaged; The enclosure completely isolates the site from the outside farmland and park, affecting people's participation in the experience.

流动flow

为了让建筑呈现出新旧交替、自由流动的场所气息，在改造设计中，我们让场地以开放的姿态面对即将来临的游客。拆除了原有坍塌的建筑和部分红砖围墙，旧红砖在场地的各个角落流动起来，从竖向的砌墙围挡变为横向的地面铺装，旧砖换了新的方向在场地生长蔓延。废弃混凝土块的应用也是如此，破碎后作为景观汀步。尽可能拆除了原有封闭围墙的场地向游客张开怀抱，吸引着来自四面八方的游客来此参观游览。

In order to give the building a sense of place where the old and the new are alternating and flowing freely, we made the site open to the coming visitors in the renovation design. The original collapsed buildings and red brick walls were removed, and the old red bricks flowed in every corner of the site, changing from vertical wall enclosure to horizontal pavement. The old bricks grew and spread in the site in a new direction. The same is true for the use of discarded concrete blocks, which are broken up and used as landscape stepping stones. Removed the original enclosed walls of the site open to visitors, attracting tourists from all sides to visit this tour.

在建筑改造方面，我们注重材质是否与原有建筑匹配和谐，是否经济适用。我们希望改造后的场所更加包容开放，所以也特别注重材质本身是否拥有通透，轻盈的质感。结合场地本身记忆，最终我们选择了聚碳酸酯板、红砖、陶瓦等材料进行了几栋建筑的针对性改造。

In architectural renovation, we pay attention to whether the material is compatible with the original building and whether it is economical and suitable. We hope that the renovated place will be more inclusive and open, so we pay special attention to whether the material itself has transparent and light texture. Based on the memory of the site, we finally chose polycarbonate panel, red brick, terra-cotta tiles and other materials to carry out targeted transformation of several buildings.

聚碳酸酯板是在乡村和农业配套设施建筑中应用很广的材料，具有透光、轻质、耐候、阻燃、隔音、高强度等优异性能，而且价格低廉，非常适合低成本低技建筑的应用。红砖和陶瓦都是原有建筑值得保留的血脉和记忆。

Polycarbonate panel is a building material widely used in rural and agricultural supporting facilities, with excellent performance of light transmission, light, weather resistance, flame retardant, sound insulation, high strength, and low price, very suitable for low-cost and low-technology building applications.  Red brick and terracotta tiles are the blood and memory of the original building deserve to be maintained.

我们将结构塌毁的建筑进行了拆除，在原址新建农机展示棚，透明的聚碳酸酯板与精巧的白色钢构营造了一个晶莹剔透、轻薄柔美的开放空间。

We demolished the collapsed building and built a new agricultural machinery exhibition shed on the site. Transparent polycarbonate panel and delicate white steel structure create a crystal clear, light and soft open space.

两栋状态较好的建筑，改造为现代农业和农耕文化展厅。红砖砌体和木构屋架全部保留并进行了局部修缮，屋面统一更换了灰色的陶瓦。同时，将聚碳酸酯板应用于局部顶棚、墙体、门窗，赋予了建筑轻盈朦胧的质感，弱化了红砖砌体带来的厚重感，让建筑呈现出新旧融合共生的状态。

Two buildings in good condition were transformed into exhibition halls of modern agriculture and farming culture. The red brick masonry and wooden roof frame were all maintained and partially repaired, and the gray terracotta tiles were replaced on the roof. At the same time, the polycarbonate panel is applied to part ceiling, wall, doors and Windows, giving the building a light and hazy texture, weakening the thick sense brought by red brick masonry, making the building present a state of integration of old and new.

我们在两栋老建筑之间用钢材和聚碳酸酯板，以种子和孔明灯的意象，做了一组悬浮在空中大小不一的透明立方体，作为场地的视觉重点。白天这些立方体像是从红砖缝里孕育出来的一粒粒飞向天空的种子，迎着太阳，晶莹夺目。夜晚，暖黄的灯光透过聚碳酸酯板盒子，带来一种明亮的漂浮感，像定格在空中的孔明灯，如梦如幻……

We used steel and polycarbonate panels between the two old buildings to create a set of transparent cubes of varying sizes suspended in the air, in the image of seeds and Kongming lanterns, as the visual focus of the site. During the day the cubes are like seeds rising from cracks in the red brick and flying into the sky, shining brightly against the sun. At night, warm yellow light through the polycarbonate board box, bringing a bright floating feeling, dreamly like Kongming lanterns frozen in the sky.

历史学家王笛认为，历史和文化是一个城市的灵魂，怎样使这个灵魂在现代化、商业化、科技化大潮的冲击下幸存是城市管理者、学者和居民都应该思考的问题。同时，这也是建筑师在面对城市更新项目时应该着重思考的问题。

The historian Di Wang believes that history and culture are the soul of a city, and how to make this soul survive under the impact of modernization, commercialization and technology is a problem that city managers, scholars and residents should consider. At the same time, this is also an issue that architects should focus on when facing urban renewal projects.

在我们看来，在进行这类项目改造时候，应注意区分“老”“破”“烂”三者的异同。“老”是陈旧，并非贬义，反而恰恰饱含历史；“破”是完整的东西受到损伤变得不完整，可在原有基础上进行修复；“烂”是不可挽回的逝去。分清三者区别后，在面对不同的老旧建筑就能采取不同策略。

In our opinion, when carrying out this kind of renovation project, attention should be paid to distinguish the similarities and differences of "old", "broken" and "dilapidated ". "Old" is antiquated, it's not derogatory but full of history; "Broken" means that the whole thing is damaged and becomes incomplete, which can be repaired on the original basis. "dilapidated " is irretrievably gone. After distinguishing the three differences, different strategies can be adopted in the face of different old building

面对不可逆的城市化进程，建筑师应该多一些人文思考。建筑从来不只是建筑本身，而是凝固的艺术，更是用智慧和激情谱写的史诗。青龙湖·漂浮种子，是我们在城市更新进程中种下的一粒小小的种子，希望这粒“漂浮种子”能够表达我们对待城市更新的态度与思考，同时也期待这粒“漂浮种子”能唤起更多城市的参与者对所栖居的城市的思考，以自己的方式保护那些珍贵的“城市文化”不在城市化进程里消失。

In the face of irreversible urbanization, architects should think more about humanity. Architecture is never just architecture itself, it’s not only congealed art, but also an epic written with wisdom and passion. Floating seeds of Qinglong Lake is a small seed we planted in the process of urban renewal. We hope that this "Floating seeds" can express our attitude and thinking about urban renewal, and also hope that this it can arouse more urban participants to think about the city they live in. In their own way to protect those precious "urban culture" does not disappear in the process of urbanization.
