在十二建筑師事務(wù)所（Twelve Architects）與英國國民信托基金會（National Trust）的合作下，曼徹斯特市中心的一座廢棄鐵路高架橋被改造成了開放的空中公園。

在這個由國民信托基金會主導(dǎo)、十二建筑師事務(wù)所設(shè)計(jì)的試點(diǎn)項(xiàng)目中，一座可追溯至維多利亞時代、位列二級保護(hù)建筑名錄的高架橋得到了修復(fù)和改造。

項(xiàng)目得到了曼徹斯特市議會、大曼徹斯特聯(lián)合管理局和當(dāng)?shù)厣鐓^(qū)民眾的支持，國民信托基金會負(fù)責(zé)以臨時性公園和試點(diǎn)項(xiàng)目的形式進(jìn)行了項(xiàng)目的首期交付。

在一年的時間中，公眾可以親臨公園參觀體驗(yàn)并提出反饋。對于項(xiàng)目二期的構(gòu)想——高架橋的永久再生而言，獲取公眾的反饋至關(guān)重要。

十二建筑師事務(wù)所的創(chuàng)始董事馬特·卡特賴特 (Matt Cartwright) 表示：“我們希望鼓勵游客發(fā)現(xiàn)并體驗(yàn)這個獨(dú)特的空間，公園致敬了組成該地歷史的經(jīng)典工業(yè)結(jié)構(gòu)。我們非常榮幸能與國民信托基金會、曼徹斯特市議會和當(dāng)?shù)厣鐓^(qū)合作開展這個項(xiàng)目，希望公眾能夠認(rèn)同，為這座標(biāo)志性建筑帶來新的生命是未來我們應(yīng)該持續(xù)進(jìn)行的事情?！?/p>

國民信托基金會城市場所主管鄧肯·萊爾德 (Duncan Laird) 補(bǔ)充道：“國民信托基金會及十二建筑師事務(wù)所在內(nèi)的廣大團(tuán)隊(duì)，共同努力開展卡斯?fàn)柗茽柕赂呒軜虻脑O(shè)計(jì)和開發(fā)，最終呈現(xiàn)出高質(zhì)量的成果。我們期待聽到公眾對場地未來的看法?！?/p>

從1969年曼徹斯特中央車站被關(guān)閉以來，這座高架橋就一直處于閑置狀態(tài)，此后僅進(jìn)行了必要的維修和保養(yǎng)。橋梁一直暴露在自然中，被灌木所覆蓋。

該試點(diǎn)計(jì)劃致力于將這座城市引以為豪的工業(yè)遺產(chǎn)與現(xiàn)代城市公園結(jié)合起來。為了實(shí)現(xiàn)這一目標(biāo)，十二建筑師事務(wù)所與國民信托基金會的景觀團(tuán)隊(duì)密切合作，設(shè)計(jì)了三處獨(dú)特的區(qū)域，引導(dǎo)訪客踏上從“現(xiàn)在”到“可能性”的高架橋發(fā)現(xiàn)之旅。

訪客通過迎賓區(qū)進(jìn)入高架橋，該處設(shè)有迎賓亭、座位和衛(wèi)生間，供即將開始預(yù)約行程的人們等候。就像劇院的幕布一樣，人們首先看到的是一面綠色的綠籬植物墻，視野的遮擋讓人更期待去發(fā)掘下一段旅程。

每隔一段時間，人們就需要穿過綠籬墻進(jìn)入高架橋的下一段。為了突出展示原歷史結(jié)構(gòu)的風(fēng)貌，這一區(qū)域的建筑或景觀干預(yù)極少，邀請人們構(gòu)想未來可能的干預(yù)措施。

在第三個區(qū)域，人們被引到“可能性”區(qū)域，花園的紅色耐候鋼花盆種滿了植物和灌木，回應(yīng)了當(dāng)?shù)鼐哂写硇缘慕?jīng)典紅磚工業(yè)建筑?；ㄅ璧牟季中问絽⒖剂巳藗兂俗疖嚶眯袝r看到的景象，有節(jié)奏地出現(xiàn)或消失，讓視線集中在前方新出現(xiàn)的花盆中?；ㄅ柚g的空間成為了周邊的的遠(yuǎn)景。

在第三個區(qū)域的盡頭，活動大樓通過大型窗戶展示剩余的一半高架橋，未經(jīng)開發(fā)的這部分鼓勵著游客們想象未來的無限可能。

重建后的高架橋不僅給城市中的人們提供了親近自然的機(jī)會，還以文化體驗(yàn)成為了徒步或騎行前往曼徹斯特南部其他綠地和景點(diǎn)的中轉(zhuǎn)站。這個歷史性地標(biāo)毗鄰科學(xué)與工業(yè)博物館和The Factory等曼徹斯特的地標(biāo)性場所，在這個充滿活力的文化遺產(chǎn)區(qū)正占據(jù)一席之地。

開放后的一年內(nèi)，高架橋公園每天接納100人免費(fèi)參觀，并通過預(yù)訂系統(tǒng)管理參觀人數(shù)。

十二建筑師事務(wù)所是一家國際性的建筑設(shè)計(jì)事務(wù)所，致力于呈現(xiàn)具有感染力和記憶點(diǎn)的設(shè)計(jì)，在總體規(guī)劃、商業(yè)、住宅、交通、教育、研究、文化、休閑、零售和醫(yī)療康養(yǎng)等不同領(lǐng)域擁有豐富的實(shí)踐經(jīng)驗(yàn)。

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.
