Renewal-Zone：曼彻斯特版高线公园︱一边试点开放 一边邀请公众限时反馈参与构想

在十二建筑师事务所（Twelve Architects）与英国国民信托基金会（National Trust）的合作下，曼彻斯特市中心的一座废弃铁路高架桥被改造成了开放的空中公园。

在这个由国民信托基金会主导、十二建筑师事务所设计的试点项目中，一座可追溯至维多利亚时代、位列二级保护建筑名录的高架桥得到了修复和改造。

卡斯尔菲尔德高架桥曾用于运输进出城市的货物，为铸铁和钢结构，现已被改造成面向所有人开放的绿色空间。

项目得到了曼彻斯特市议会、大曼彻斯特联合管理局和当地社区民众的支持，国民信托基金会负责以临时性公园和试点项目的形式进行了项目的首期交付。

在一年的时间中，公众可以亲临公园参观体验并提出反馈。对于项目二期的构想——高架桥的永久再生而言，获取公众的反馈至关重要。

十二建筑师事务所的创始董事马特·卡特赖特 (Matt Cartwright) 表示：“我们希望鼓励游客发现并体验这个独特的空间，公园致敬了组成该地历史的经典工业结构。我们非常荣幸能与国民信托基金会、曼彻斯特市议会和当地社区合作开展这个项目，希望公众能够认同，为这座标志性建筑带来新的生命是未来我们应该持续进行的事情。”

国民信托基金会城市场所主管邓肯·莱尔德 (Duncan Laird) 补充道：“国民信托基金会及十二建筑师事务所在内的广大团队，共同努力开展卡斯尔菲尔德高架桥的设计和开发，最终呈现出高质量的成果。我们期待听到公众对场地未来的看法。”

从1969年曼彻斯特中央车站被关闭以来，这座高架桥就一直处于闲置状态，此后仅进行了必要的维修和保养。桥梁一直暴露在自然中，被灌木所覆盖。

该试点计划致力于将这座城市引以为豪的工业遗产与现代城市公园结合起来。为了实现这一目标，十二建筑师事务所与国民信托基金会的景观团队密切合作，设计了三处独特的区域，引导访客踏上从“现在”到“可能性”的高架桥发现之旅。

访客通过迎宾区进入高架桥，该处设有迎宾亭、座位和卫生间，供即将开始预约行程的人们等候。就像剧院的幕布一样，人们首先看到的是一面绿色的绿篱植物墙，视野的遮挡让人更期待去发掘下一段旅程。

每隔一段时间，人们就需要穿过绿篱墙进入高架桥的下一段。为了突出展示原历史结构的风貌，这一区域的建筑或景观干预极少，邀请人们构想未来可能的干预措施。

在第三个区域，人们被引到“可能性”区域，花园的红色耐候钢花盆种满了植物和灌木，回应了当地具有代表性的经典红砖工业建筑。花盆的布局形式参考了人们乘坐火车旅行时看到的景象，有节奏地出现或消失，让视线集中在前方新出现的花盆中。花盆之间的空间成为了周边的的远景。

这里还设有一个生长区和“合作区”，一些城市合作伙伴在此展示各自的装置，目前为城市荒野、科学与工业博物馆、树木之城和卡斯尔菲尔德论坛所用。

在第三个区域的尽头，活动大楼通过大型窗户展示剩余的一半高架桥，未经开发的这部分鼓励着游客们想象未来的无限可能。

重建后的高架桥不仅给城市中的人们提供了亲近自然的机会，还以文化体验成为了徒步或骑行前往曼彻斯特南部其他绿地和景点的中转站。这个历史性地标毗邻科学与工业博物馆和The Factory等曼彻斯特的地标性场所，在这个充满活力的文化遗产区正占据一席之地。

开放后的一年内，高架桥公园每天接纳100人免费参观，并通过预订系统管理参观人数。

Twelve Architects and the National Trust have transformed a disused railway viaduct in the heart of Manchester into a public sky park.

A grade II-listed viaduct dating back to Victorian times has been restored and reinvented in a pilot scheme led by the National Trust and designed by Twelve Architects.

The Castlefield Viaduct, which is made of cast-iron and steel and was once used to transport goods in and out of the city, has been transformed into a green space that is accessible for all.

Supported by Manchester City Council, Greater Manchester Combined Authority and members of the local community, the National Trust was responsible for delivering the first phase of the project in the form of a temporary park and pilot installation.

Throughout the year, members of the public will be given the opportunity to visit and experience the park first-hand, whilst giving their feedback about the plans. Gaining feedback from the community is a key step in shaping the vision for the second phase of the project: the permanent regeneration of the viaduct.

Matt Cartwright, Founding Director at Twelve Architects, said:

“We want to encourage visitors to discover and enjoy this distinctive space, which pays homage to the classic industrial structure which has shaped this area's history. Working on this project with the National Trust, Manchester City Council and the local community has been a huge privilege, and I hope the public agree that bringing new life to this iconic structure is something we should build on in the future.”

Duncan Laird, Head of Urban Places at the National Trust, added:

“The National Trust and its wider team, including Twelve Architects, took a collegiate approach to Castlefield Viaduct's design development, which has resulted in a high-quality finished project. We look forward to hearing what the public have to say about the future of the space.”

The viaduct has stood unused since 1969 when Manchester Central station closed, with only essential repairs and maintenance carried out since, leaving the bridge exposed to the elements and covered in shrubs.

The pilot concept seeks to marry the city's proud industrial heritage with a modern urban park concept. To achieve this, Twelve Architects has worked closely with the landscape team at the National Trust to devise three unique zones, which take visitors on a journey of discovery from the viaduct that 'is' to the viaduct that 'could be'.

Visitors enter the viaduct through a welcome area, which contains a welcome kiosk, seating and toilets for those waiting to begin their pre-booked tours. Like with curtains at a theatre, visitors are presented with a green screen 'living wall', which obstructs their view of the viaduct, leaving them in eager anticipation of what they will discover in the next phase of their journey.

At a timed intervals people pass the green screen and enter the next stretch of the viaduct. With minimal architectural or landscaping intervention, this zone focuses on showcasing the existing structure and inviting visitors to imagine potential future interventions.

At the third zone visitors are introduced to the viaduct that 'could be'. This includes a garden filled with plants and shrubs contained within red COR-TEN steel planters, a respectful nod to the classic industrial red brick buildings so typical of the area. The placement of the planters references the effect people experience when travelling on a train, as objects rhythmically appear and disappear, allowing the eye to focus on the new planters in the foreground, with spaces between them to frame the long-distance views of the surroundings.

It also features a growing area and ‘Partner Plots’ where city partners are exhibiting their own installations. These plots are currently occupied by Urban Wilderness, the Science and Industry Museum, City of Trees and Castlefield Forum.

At the end of the third zone is the events building that has a large window showing the remaining half of the viaduct, completely untouched, encouraging visitors to imagine the possibilities of the viaduct's future.

As well as bringing people closer to nature in the city, the regenerated viaduct will act as a stepping- stone to other green spaces and attractions in south Manchester discoverable on foot or bike, adding to the cultural offer. The historic landmark is taking its place in this vibrant area for culture and heritage, sitting alongside iconic Manchester venues including the Science and Industry Museum and The Factory.

One hundred people a day will be able to visit the viaduct for one year. Entry is free, with a booking system in place to help manage numbers.
