项目说明
PROJECT NARRATIVE

背景

75年以来，沃克艺术中心一直是美国最顶尖的当代艺术机构之一。沃克园区坐落在明尼阿波里斯市中心外围的一处斜坡上，与城市里最负盛名的公园和湖泊系统直接相连。沃克艺术中心容纳了众多具有挑战性的多样化项目，着重关注于视觉、表演和媒体艺术。

园区内目前已有Edward Larrabee Barnes（1971）和Herzog & de Meuron （2005）等事务所设计的建筑杰作、由Edward Larrabee Barnes（1999）和Michael van Valkenburg（1992）设计的明尼阿波里斯雕塑花园（MSG），以及由Michel Desvigne（2005）设计的广场，凭借这些作品，沃克园区为艺术的呈现提供了多学科和多样化的方法。不过，Herzog & de Meuron的扩建项目使得主入口从雕塑花园被移动到Hennepin大道，这使得园区的辨识度和交通流线变得不甚明确。此外，艺术中心还缺乏一个足够吸引人的、能够将独特的建筑与标志性的景观统一起来的公共空间。

项目任务

在Guthrie剧院于2006年重建之后，与沃克园区相邻的6英亩坡地被遗留下来，且未能发挥出从视觉上与建筑相统一的潜力。该项目的重点是将Wurtele高地花园融入沃克艺术中心19英亩的场地以及明尼阿波里斯雕塑花园。景观设计的目标是通过新的入口建筑来建立清晰的交通流线和视觉体验。

设计方案

景观设计师和建筑师希望通过共同合作来为园区创造新的愿景。花园内新增加的建筑旨在为游客营造更加友好和热情的入园氛围。作为如今园区内的核心地带，这座新增加的场馆使博物馆的身份感和存在感得到了明显的增强。更新后的花园由十二个不同的植被体块（Volumes）组成，包含大量的灌木、观赏草类以及坐落着优美雕塑的几何景观草坪。

设计细项

体块1，位于Vineland Place和Hennepin大道的拐角处，是一个种满欧洲红瑞木（Red Dogwood）的方形网格状场地，与雕塑花园一侧的街道共同构成通往园区的新路径。

沿Hennepin大道分布的两个新体块。体块2的特色是一片唐棣树林，在不同季节展示出不同的美景。体块3种植着韩国梨，同时设有带座位的混凝土花池和檀木长椅。细密的俄罗斯鼠尾草为背景处形态简洁的白色建筑提供了肌理和色彩上的对比。

体块4的桦木林形成了一个隐蔽的屏墙，遮挡了来自Groveland平台周边服务区的视线。单树干的树木被布置在边长为5英尺网格上，呈现出森林般的边界。由宾夕法尼亚莎草构成的柔软地毯成为了该体块的林下植被。

体块5位于服务区域的北侧，带来由黄松构成的屏障。这种植物能够在全年呈现出美丽的色彩和纹理，即使在冬季也能带来绿意。林地花卉和蓝莓在由松针铺成的“地毯”间茁壮生长。

体块6种植着重金属柳枝稷，欢迎着人们进入Turrell（2005）的作品《Sky Pesher》。在整个场地中，既有雕塑和新雕塑的选址和布局均经过了精心策划，以带来最佳的观展体验。

体块7种植着华丽的红枫树，它位于一个14英尺高的人造土丘之上，其下方容纳着停车场空间。这块新的场地为人们带来了明尼阿波里斯市中心天际线的视野，同时还为一年一度的摇滚花园音乐节（Rock the Garden）提供了座位和场地。

体块8种植着代表明尼苏达州的红松树，这里摆放着由Akagawa设计的雕塑《花园座位》，从这里可以望见雕塑花园、大教堂以及明尼阿波里斯的城市天际线。

体块9是一片围绕着混凝土车库入口分布的纸桦树林，不仅看上去充满生机，还将入口的位置突显出来。寻路标识将两个入口点清晰地连接起来。

体块10以创造性的方式将停车场的减压通风口隐藏起来。大规模种植的本地耐旱多年生植物和矮灌木带来了随四季变化的色彩和纹理。

曲折而倾斜的深色混凝土步道将不同的体块连接起来，使游客得以在花园中一边漫步一边欣赏植物和艺术品，同时享受新建成的雕塑花园和远处的城市美景。

沿着楼梯或曲折的步道向下走，游客将到达Esker Grove餐厅外部的庭院空间。在这里，皂荚树的茂密树冠为体块11赋予了特征。游客们可以坐在树荫下用餐、欣赏植物和艺术。黑色的混凝土座位墙定义了庭院空间的边界。

体块12是一片位于白色混凝土广场内的有着清晰几何形状的草坪，其中摆放着Larner的雕塑作品《X》。从该空间可以直接通向入口或街道对面新建的雕塑花园，同时与Wurtele高地花园同时成沃克艺术中心的一个全新、清晰而大胆的标志。

材料与安装方法

混凝土步道和地形是定义花园和技术性干预的两个要素。

混凝土步道作为花园的连接要素，为游客提供了一条方便的路线，使其可以自如地探索和欣赏花园及其内部的艺术品。步道系统的设计经过了全面而详尽的研究。景观设计师希望通过在景观中置入纹理粗糙的深色元素来连接花园的不同体块。为了实现这一目标，执行景观设计师与建筑师、工程师、混凝土工匠和供应商进行了合作，旨在开发出理想的外观和饰面系统。最后呈现出的结果为黑色的混凝土步道，其粗糙而倾斜的表面与游客行进的路线形成垂直的关系。

地形作为另一个关键的设计要素被用于创造空间并为景观赋予趣味性。体块7的地形通过在土工泡沫的子结构上建立独特的轻质土壤系统得以实现，克服了下方停车库带来的结构限制。在设计阶段初期，景观设计师便与建筑师、工程师和地质泡沫供应商合作建立了系统模型，对上方的土壤和树木提供支撑。14英尺高的土丘一方面为花园赋予了独特的碗状形态，另一方面也带来了城市天际线的壮观景色。此外，用于固定树木的锚固系统还能够防止地质泡沫上的植被因大风侵袭而翻倒。该系统是通过在每棵树下铺设塑料网格并借助织物和缆绳绑定树木而实现的。放置在塑料网格上的土壤能够通过自身重量使树木保持在合适的位置。

结语

设计和执行阶段的景观设计师与其他设计学科的人士以及沃克艺术中心通力合作，为所有人创造了一个全新的入口，以及一座能够供所有人欣赏艺术和风景的优美花园。

PROJECT NARRATIVE

BACKGROUND

For more than 75 years the Walker Art Center has been one of the nation’s top contemporary art institutions. Nestled on a sloping hill just outside of downtown Minneapolis and connected directly to the city’s renowned system of parks and lakes, the Walker campus is home to a challenging and diverse program focused on visual, performing and media arts.

With a campus that includes existing architectural masterpieces by Edward Larrabee Barnes (1971) and Herzog and de Meuron (2005), the Minneapolis Sculpture Garden (MSG) by Edward Larrabee Barnes (1999) and Michael van Valkenburg (1992), and plaza by Michel Desvigne (2005) the Walker offers a multidisciplinary and diverse approach to the interpretation of art. However, when the Herzog expansion shifted the main entry away from the MSG to Hennepin Avenue, the Walker suffered from an absence of clear identity and circulation, particularly from the MSG. In addition, the art center lacked an engaging public space that could unify the Walker’s distinctive architecture and iconic landscape.

PROJECT SCOPE

When the Guthrie Theatre was relocated in 2006, Walker’s adjacent six-acre hillside was left unfinished and failing to meet its potential in visual significance and coherence with the architecture. Integrating the Wurtele Upper Garden into the newly unified 19-acre Walker Art Center and Minneapolis Sculpture Garden campus was the key focus. The landscape design aimed to create circulation and visual clarity in concert with the new entry pavilion addition.

DESIGN PROGRAM

The design landscape architect worked in concert with the design architect to create, a new vision for the campus. The design concept of a new building addition within a garden created a more visitor-friendly and welcoming entry experience. The new addition is now the epicenter of the Walker Art Center’s campus and strengthens the museum’s identity and presence. The updated garden campus is comprised of twelve varying plant material Volumes that are expressed by masses of shrubs, ornamental grasses, and formal geometric bosques of trees or a crisp, faceted plane of lawn holding a beautiful sculpture.

DESIGN INTENT

Volume 1, a square grid of Red Dogwood anchors the corner of Vineland Place and Hennepin Avenue. Together with the flanking mass on the Sculpture Garden side of the street they serve as a gateway to announce the entry to the newly unified campus.

Further along the Hennepin Avenue frontage are two additional plant Volumes. Volume 2 is accentuated by a grove of Serviceberry that offers a beautiful display through the seasons. A concrete seatwall planter with an ipe bench holds the Volume 3 bosque of Korean Pear. An understory of wispy Russian Sage offers contrasting textures and colors to the crisp lines of the white building in the background.

The River Birch of Volume 4 provides a veiled screen to limit the views of the service area along Groveland Terrace. Single stem trees are placed on a varying 5 foot grid to create a forest-like edge. A soft carpet of Pennsylvania Sedge serves as the understory planting.

On the north side of the service area, Volume 5 provides additional screening through the use of Ponderosa Pine. This planting serves as a welcomed year round color and texture mass providing green even in the winter months. An understory of woodland flowers and blueberries will thrive in the pine needle carpet below.

The Heavy Metal Switch Grasses of Volume 6 celebrates the entry to Sky Pesher by Turrell (2005). Throughout the site, coordination and siting of existing and new sculpture in the landscape was thoughtfully planned for displaying and experiencing the artwork.

The majestic bosque of Autumn Blaze Maples comprised by Volume 7 is situated in the garden on the 14-foot artificial earthen mound created by geofoam over the parking garage below. This new landform offers expansive views to the Minneapolis downtown skyline and provides the seating for events such as the annual fundraiser Rock the Garden.

Red Pine, Minnesota’s State tree forms the tree room of Volume 8. Thesculpture Garden Seating by Akagawa was sited to capitalize on the view of the Sculpture Garden, Basilica and Minneapolis downtown skyline.

Volume 9, a grove of Paper Birch, surrounds the concrete parking garage entrance with a vibrant presence, easing the ability to find the entrance. The wayfinding signage clearly connects the two points of entry.

To mask a relief air vent for the parking garage below, Volume 10 was creatively developed. A perennial mass planting of native and adaptive low water use perennials and low shrubs provides a wondrous seasonal display of color and varied textures.

A sinuous, zigzagging accessible walk of raked black concrete connects the garden volumes allowing visitors to wander through the garden appreciating the plants and art while enjoying views to the newly completed sculpture garden and surrounding city.

Marching down the hill via either the stair or zigzag path, one lands in the patio outside of Esker Grove, the new dining room. Here, an overstory of Skyline Honeylocusts forms Volume 11. Visitors may sit and dine beneath the filtered shade, appreciating the plants and art while enjoying food and the company of others. A black concrete seatwall holds the edge of the patio space.

Volume 12 is defined by a crisply sculpted lawn set within a white concrete plaza holds the sculpture Xby Larner. This space leads to the addition entry or MSG across the street and together with the Wurtele Upper Garden it has created a new, clear, bold identity for the Walker Art Center.

MATERIAL AND INSTALLATION METHODS

Two elements that define the garden and required research and technical intervention were the concrete walks and landforms.

The concrete walks are the connecting element of the garden. They provide an accessible route for visitors to explore and enjoy the garden and the art located within. Exhaustive research went into the development of the walks. The design landscape architect desired a dark, rough textured expression in the landscape that linked the Volumes together. To accomplish this, the executive landscape architect collaborated with architects, engineers, concrete finishers and the supplier to develop the desired appearance and finish. The end product was a walk of black concrete with a rough raked finish perpendicular to the path of travel.

Landform, a key element of the design concept was used to create space and add interest to the landscape. To achieve this, a unique system of lightweight soil over a geofoam substructure was utilized to express the landform of Volume 7. The use of this system was required due to structure limitations of the parking garage below. Early in the design process the landscape architect collaborated with architects, engineers and the geofoam supplier to model and design the system to support the soil and trees above. Together, the team designed a 14-foot high mound that was designed to create the bowl of the garden and provide views of the Minneapolis downtown skyline. Additionally, a tree anchoring system was utilized to secure the large trees, thus preventing them from tipping over due to high winds on the exposed geofoam mound. This system was developed by using a plastic grid under each tree and then attaching the tree to it with a fabric collar and cables. The weight of the soil placed over the plastic grid around the trees provided the resistance to hold the trees in place.

CONCLUSION

Together, the design and executive landscape architects worked with other design disciplines and the Walker to create a new entry and garden for all to enjoy art in the landscape.
