有一本书叫做《为什么伟大不能被计划》，里面罗列了包括CHATGPT在内的许多颠覆性的创造——他们都不是被完整的计划出来的，而是摸着一块块踏脚石依靠着探索精神一步步走出来的。而城市更新就是这样一件伟大的事情：多年的城市发展，让整座老城地上地下,表里内外都有极其丰富的信息要素，更新的过程更是如一场漫长的微创手术，或者更像是寻宝过程——目标未知，路线不定。寻宝者的任务，是在寻找一个个的踏脚石立足点，努力探索尽量大的区域，再看看探索过的区域里，都有哪些价值连城的小玩意。

The book called “Why Greatness Cannot Be Planned” lists many disruptive creations, including CHATGPT, which are not planned in their entirety, but are instead built step by step relying on an exploratory spirit like stepping on stones. Urban renewal is such a great thing: years of urban development have endowed the entire old city, inside and out, with extremely rich information elements. The process of renewal is like a long, minimally invasive surgery or more like a treasure hunt—the goal is unknown, and the path is uncertain. The task of the treasure hunter is to find stepping stones and footholds, explore the largest possible area, and then see what priceless treasures are found in the areas explored.

-项目背景-

Background

项目位于宜昌市夷陵区的最核心区域，是东湖大道城市更新项目的重要节点。更新前的城市空间和面貌已经不再能满足小溪塔片区居民的生活需求。项目西侧与南侧分别是夷陵区重要的城市主干道东湖大道与夷兴大道，因此这个路口在更新前充斥着拥堵的车流和人流。于是拓宽车行道路成为改造的第一块踏脚石。拓宽后的建筑显得面貌陈旧，人行空间拥挤，因此在不断地讨论推翻再重构之后，拆除这座金三角大楼成为第二块踏脚石。

The project is located in the most central area of Yiling District, Yichang City, and is an important node of the Donghu Avenue Urban Renewal Project. The urban space and appearance before the renewal no longer meet the living needs of the residents in the Xiaoxita area. To the west and south of the project are Donghu Avenue and Yixing Avenue, which are important urban arteries in Yiling District, so this intersection was filled with congested traffic and people before the renewal. Widening the carriageway became the first stepping stone for the renovation. After the widening, the building looked outdated and the pedestrian space was crowded, so the demolition of the Golden Triangle building became the second stepping stone after continuous discussion and reconstruction.

当得知将拆除一栋楼打造一座街角花园的时候，我们对这个不到3000平方的空间肃然起敬了起来，因为这个3000平方是对接未来夷兴广场重要空间节点的踏脚石，给未来城市核心绿地做好开头；也将会成为小溪塔老城城市更新的踏脚石，给小溪塔区公园城市营造打下一个模板；更是当下与未来生活链接的一个踏脚石，给夷陵区未来城市活力绿道营建的启动节点。

When we learned that a building would be demolished to create a street corner garden, we had a deep respect for this space of less than 3000 square meters, because this 3000 square meter is a stepping stone to connect with the important spatial nodes of Yixing Square in the future, laying a good foundation for the core green space of the city in the future; It will also become a stepping stone for the urban renewal of Xiaoxita Old Town, laying a template for the creation of a park city in Xiaoxita District; It is also a stepping stone connecting current and future life, serving as a starting point for the construction of a vibrant greenway in Yiling District's future cities.

-场地现状-

Site Analysis

拆除建筑后，场地涌现了许多新的问题：大量的地下管线影响场地植物种植、原本是背街面的破旧建筑外立面被暴露出来、城市的变电房也赫然出现，以及由于山地丘陵城市带来的高差关系成为了场地背景。在整个设计过程里，我们探讨所有的可能性，与周边建筑的交通关系、与未来城市公园的交流方式、城市路过人群行为模式、空间使用的可能性。

After the demolition of the building, many new problems emerged on the site: a large number of underground pipelines affected the planting on the site, the dilapidated façade of the building, which was originally a backstreet, was exposed, the city's power substation also appeared, and the elevation difference due to the hilly city became the backdrop of the site. Throughout the design process, we explored all the possibilities, the traffic relationship with the neighbouring buildings, the way of communication with the future city park, the behavioural patterns of the people passing through the city, and the possibilities of the use of the space.

-设计挑战-

The Question

这样的复杂条件，自然带来了多重的设计挑战：

01. 如何有效引导人行道人流进入空间。

作为夷陵区最繁忙的十字路口，每日会有大量的人流在此路口停留驻足，如何构建场地肌理有效引导人群进入空间内部，并不影响城市人行道交通，是第一挑战。

02. 如何构筑可以停留的场地空间

由即将更新的建筑山墙面、变电箱、变电房、城市地台围合出来的场地空间面积不到3000方，为场地引入一个什么样的停留空间，让这3000方的空间更具停留的吸引力，是第二挑战。

03.如何与周边居民的生活有效耦合

作为一个老城区的街道一角，周边的社区大多为上世纪的多层住宅，楼间距逼仄活动空间狭小，在这个公园城市与活力绿道的启动节点置入什么样的活力功能，才能与周边社区、学校的功能充分耦合，是第三挑战。

Such complex conditions naturally bring multiple design challenges:

01. How to effectively guide the pedestrian flow into the space.

As the busiest intersection in Yiling District, a large number of people will stop at this intersection every day. How to construct the site texture to effectively guide the crowd into the space without affecting the traffic of the urban pavement is the first challenge.

02. How to construct a space where people can stay?

The area of the site space enclosed by the wall of the building to be renewed, the transformer box, the transformer room, and the urban terrace is less than 3,000 square metres, so what kind of space can be introduced into the site, and what kind of space can make this 3,000 square metres of space more attractive for stopping is the second challenge.

03. How to effectively couple with the life of neighbouring residents

As a corner of a street in an old urban area, most of the surrounding communities are multi story residential buildings from the last century, with narrow activity spaces between buildings. What kind of vitality functions should be placed at the starting point of this park city and vitality greenway to fully couple with the functions of the surrounding communities and schools is the third challenge.

-设计策略-

Title Solution

01. 动线的引导：

稳定中的无限运动水滴构建起来的空间秩序，有效的引导着城市人流。由旋转花坛、地面LED灯带构成的环，不是单纯的静态同心环，是类似运行中的曼陀罗曲线定格的那一瞬间。类曼陀罗曲线带来的瞬时动感，让整个场地既有如水滴落下的涟漪感，又有水滴甩出环绕的动态感，所有动线都依着一个内核而生，有互相独立的动力又有互相依存态势。

01. Guidance of movement:

The spatial order built up by the infinite movement of water drops in the stability effectively guides the flow of people in the city. The ring composed of rotating flower beds and ground LED light strips is not a mere static concentric ring, it is a moment similar to a running mandala curve framed. The instantaneous movement brought by the curve of mandala makes the whole site both the ripple sense of water droplets, and the dynamic sense of water droplets throwing around. All the dynamic lines are born on a core, with independent power and interdependent situation.

02. 边界的构建：

定格中的动态元素构架为场地提供停留边界。以浓密绿化弱化暂时无法提升的建筑边界，不停环绕的曼陀罗曲线在定格中成为场地边界富有动感的廊架、花坛与座椅。廊架作为边界，既是行人停留空间，也是经营空间，更是未来城市绿地的入口空间。人行道边界的花坛，即吸引人进入又引导人路过，也为行人提供临时的等候空间。

02. Boundary construction:

The dynamic elements in the frame provide the boundary for the site to stay. The dense greenery weakens the building boundary that cannot be raised temporarily, and the mandala curve that keeps circling around becomes the dynamic corridor, flower bed and seat of the site boundary in the frame. As a boundary, the corridor is a space for pedestrians to stay, a space for business, and an entrance space for the future green space of the city. The flower beds at the boundary of the pavement attract people to enter and guide them to pass by, and also provide temporary waiting space for pedestrians.

▲ 旋转水滴廊、水滴城市家具构成了场地功能边界

03. 内核的注入：

一个下沉的安静草坪，或许会让人停留下来略作休息，但远没有一个有活动内容的活力小山丘来的有吸引力，而下沉的草坪即刻变身成为一个天然的安全活动场所。周边学校上下学的孩童以及大量生活在旧城中的市民，都需要一个充满无限可能性的全龄活动场地来缝合日常生活空间的缺失，这个街角注定即能安静停留又能活力满满。

03. The infusion of the kernel:

A quiet sunken lawn may make people pause for a while to rest, but it is far less attractive than a lively hill with activity content, and the sunken lawn immediately transforms into a natural and safe activity place. With children coming and going from the neighbouring schools and a large number of citizens living in the old city in need of an all-age activity space with endless possibilities to sew up the lack of space for their daily lives, this corner is destined to be both quiet and full of energy.

▲ 活力内核功能的注入

如此三步策略，每一步都似乎是空间自己在自动生成，一气呵成，动静相辅，设计师要做的，只是在这件事情中摸清事件边界，找到一步步踏脚石，助推整个事件的形成。

In this three-step strategy, each step seems to be generated automatically by the space itself, all in one go, complementing each other with movement and static, and what the designer has to do is just to find out the boundaries of the event in this matter, and find a stepping stone to help the formation of the whole event.

-设计要素-

Space Design

整个场地由活力山丘、旋转水滴廊、水滴城市家具、雨水花园等多个设计要素构成，构建成为了充满活力的街角公园。

The entire site consists of a number of design elements such as vibrant hills, rotating water drop corridors, water drop urban furniture, rain gardens, etc., which are constructed to become a vibrant corner park.

▲ 空间要素及其细节要素

- 活力山丘 Vitality Hill -

高出草坪1.2米的小山丘带来的活动空间，是献给周边孩子的礼物。草坪下沉450公分，让这个场地的边界天然有了家长看护的座椅。活动转盘、攀爬山丘、钻洞筒、大小两组滑梯让孩子们有无限玩乐的可能。草坪上甩出的草坪水滴雕塑，也成为了儿童跑跳的对象。

The space for activities brought about by the hill that rises 1.2 metres above the lawn is a gift to the children in the neighbourhood. The lawn is sunk 450cm, giving this venue a natural border with seating for parents to watch over. An activity carousel, a climbing hill, a drilling tube, and two sets of slides, one large and one small, give the children unlimited possibilities for fun. The sculpture of lawn water droplets thrown out on the lawn has also become the object of children's running and jumping.

- 旋转水滴廊 Water Droplet Rack -

类曼陀罗曲线升起的折纸式渐变长廊，在空间中保持了旋转水滴的动态要素，是场地休憩边界的同时，也是一个南高北低的雨水收集长廊。在落雨时，雨水顺棚顶而泄，汇于廊架北段一处，顺着廊下的金属雨链汇聚于地面的不锈钢集水装置。

The origami gradient corridor with the curve of mandala maintains the dynamic elements of rotating water droplets in the space. It is not only the rest boundary of the site, but also a rainwater collection corridor high in the south and low in the north. In the rain, the rain discharges along the top of the shed and sinks in the north section of the corridor. Along the metal rain chain under the corridor converges on the stainless steel water collection device on the ground.

将廊架自上而下拆解，可分为双曲面异形不锈钢板顶板、桁架结构骨架、双曲面异形不锈钢板天花、树状结构支撑柱、独立桩基础五个层次。顶棚的三层都以空间双曲面渐变折纸形态互相精密咬合，将水滴旋转时的形态无限定格。其下由树状支撑柱界定出的廊下空间，为市民提供了休憩、等待、看护的场所。

The corridor frame is disassembled from top to bottom, and can be divided into five levels: hyperbolic shaped stainless steel plate roof, truss structure skeleton, hyperbolic shaped stainless steel plate ceiling, tree structure support columns, and independent pile foundation. The three layers of the ceiling are all precision biting each other in the form of space hyperbolic gradient origami, framing the infinite form of the water droplets as they rotate. The space under the corridor defined by the tree-like support columns underneath provides a place for the public to rest, wait and look after.

- 水滴城市家具 Urban Furniture -

水滴旋转出的瞬间动态，衍化成为了这个街角独一无二的城市家具。无论是草坪上甩出的水滴雕塑、还是廊架下可让人躺坐的水滴座椅、或者作为城市边界的旋转水滴花坛，都让这个街角更具识别性和魅力。

The instantaneous dynamics of the water droplets have become the unique urban furniture on this street corner. Whether it is the water drop sculpture flung on the lawn, the water drop seat under the veranda where people can recline, or the rotating water drop flower bed as the city boundary, it makes the corner more recognisable and attractive.

- 雨水花园 RAIN GARDEN -

旋转水滴公园也是一次城市雨水花园的小型实践，充分收集了场地内地面和水滴廊顶的雨水，通过植物、沙土的综合作用使雨水得到净化，并使之逐渐渗入土壤，涵养地下水。

The rotating water drop park is also a small-scale practice of urban rain garden, which fully collects rainwater from the ground and the roof of the water drop gallery on the site, purifies the rainwater through the combined effect of plants, sand and soil, and allows it to gradually infiltrate into the soil and nourish the groundwater.

-设计落地-

Construction

在这个由动态旋转水滴为内核的场地构建过程中，有大量非标物料的落地，包括且不限于廊架、花坛、雕塑、座椅。设计在过程中以精细化的场地白模推敲空间尺度分析构成关系，并深入参与到构建的每一个主材和节点把控中。

In the construction process of this site with dynamic rotating water droplets as the core, a large number of non-standard materials are landed, including but not limited to corridors, flower beds, sculptures and seats. In the process, the design uses the refined white model of the site to push the spatial scale to analyse the compositional relationship, and deeply participates in the construction of each main material and node control.

-写在最后-

Afterword

建成后整个场地成为了一个拥有行人等候空间、大人看护空间、孩童玩耍空间、城市经营空间的多维度复合型街角公园，甚至被城市居民自由发挥成了闲人发呆空间、小商贩摆摊空间、阿姨舞蹈空间、儿童放风筝空间等等意想不到的使用方式。于是这样的故事会每天在这个公园里发生：大爷躺在廊架下戴着墨镜看着小孙儿和玩伴在下沉草坪里跑跳；有可能大孙儿正在旁边的小学里上课马上下学要路过这里；说不定老伴在旁边穿着鲜艳的衣服跳着广场舞；搞不好女儿在一旁花坛上坐着抠手机照看着孩子；也可能儿子刚好在旁边的大楼里上班，而自己家正好在边上的夷陵三巷，这算不算一个街角公园给一座老城带来的幸福感容器。用一个动态瞬间定格的圆生成的公园空间，解决街角当下我们能看到的所有问题以及未来可能会出现的问题，给这座不断更新中的老城一丝丝幸福感，作为设计师好像也有了点纳什均衡的满足感，最后感谢这个街角公园所有参与者的付出。

After completion, the entire site has become a multi-dimensional compound street corner park with pedestrian waiting space, adult care space, children's play space, and urban management space. It has even been freely utilized by urban residents as a space for idle people to daydream, a space for small vendors to set up stalls, a space for aunties to dance, a space for children to fly kites, and other unexpected ways of use. So this kind of story would happen every day in this park: the old man lying under the porch wearing sunglasses, watching his little grandson and playmates running and jumping in the sunken lawn; It is possible that the eldest grandson is attending classes in the nearby elementary school and is about to pass by after school; Perhaps his spouse is dancing square dancing in bright clothes next to him; Maybe his daughter is sitting on the flower bed next to her, picking her phone and taking care of the child; It is also possible that his son happens to be working in a nearby building, while his own home happens to be in Yiling Sanxiang, which can be considered a container of happiness brought by a street corner park to an old city. The park space generated by a dynamic and instantly frozen circle solves all the problems we can see at the street corner and the potential problems that may arise in the future, giving this constantly updating old city a sense of happiness. As a designer, it seems that I also have a sense of Nash equilibrium satisfaction. Finally, I thank all the participants in this street corner park for their efforts.
