MASTER PLAN
As part of the 2019 World Horticultural Exposition, a number of strategic goals/ principals have guided the conceptual and schematic design of the Hargreaves Associates plot D32 garden - EAST AND WEST;
• To represent the core values of the 2019 Beijing Horticulture Expo as a whole, and the desire for creative learning about sustainability and public space making within the Education and the Future Zone Creative Gardens.
• To create a multi-layered space that allows for engagement and learning, yet in an eloquently simple, direct, and easy to connect-with formal design.
• And finally, to develop a truly vivid, and captivatingly experiential garden during the exposition, that will dynamically evolve as an integral component of a larger legacy public park as a resource for Yanqing and the Beijing region at large in the future - post expo.
东方和西方”。 整体性的体现2019年北京园博会的核心 价值，满足教育园和未来创意园中对可 持续性和公共空间塑造的创新性理解的 需求。 • 通过简单流畅，直接，连通性好的规整的 设计，创造多层次的，能够提供互动和体 验学习的空间。 • 在博览会期间提供一个真正的生动，吸 引人的体验式公园，在博览会之后动态 演变，作为延庆和北京更广泛区域之内 的大型公共公园系统不可分割的一部 分 。
Nearly one eighth of the worlds plants (roughly 31,000 species) are native to China, many of which have been exported and cultivated in other similar regions of the world over the past few millennium. This is evident in North America, where a wide variety of the species commonly planted in contemporary parks and public spaces throughout the continent are endemic China.

It is this seemingly untold story that EAST AND WEST seeks to explore.
The proposed garden is divided into four Site Character Zones that together create an abstraction of global Plant Hardiness Zones. Plant species from a variety of hardiness zones common to both China and the United States are on display in Site Character Zones as representations of the real world, and contribute to a unique experience in each. In The ebb and flow of the subdividing hedge rows create a series of micro spaces within, that allow visitors to engage and interact with the garden in a variety of ways and at their own pace.
A hierarchy of pedestrian paths permeate through the garden in a maze-like network. This configuration promotes fluid movement between the more social group viewing areas along the wide formal perimeter walk, with the immersive experience of the smaller paths within. The curvilinear hedge rows gracefully stretch vertically, where the datum created by their sculpturally form raises to allow for archway openings through and between zones.
The terraced elevation of the zones provides an underlying infrastructural function, where stormwater is collected in low-lying wetlands. At the same time, the terracing uniquely engages Expo visitors in the adjacent public spaces through curated views, encouraging an exploration of the garden and the opportunity to learn about how China’s native plant species have influenced public space design in the United States and throughout the world.
这个看起来不为人知的故事引导我们去探 索“东方和西方”的理念。 公园的设计被分成四个“地域特色展示区”， 共同创建一个全球植物在不同抗寒带分布的 抽象概念。来自不同抗寒带的在美国和中国 都常见的物种在“地域特色区”展出，作为真 实世界的呈现，并营造各具特色的体验。在分 隔篱笆的起伏流动中，创造一系列微空间，让 游客根据自己的游览进程，通过各种方式和 花园互动。 各层级的步道延伸到花园的各个角落，形成 迷宫一样的网络。这种构成促进了宽敞正式 的外围步道上的团体参观体验和内部小径上 的更为私密的游览体验的流通。弯弯曲曲的 树篱在竖向空间上舒展，雕塑形的树篱抬高， 制造出拱形门洞，为各地域特色区之间提供 了开口。 高度变化的平台也具有潜在的基础设施方面 的功能，雨水被收集汇集到低处的湿地。同 时，平台给在公园附近区域的博览会游览者 提供了独特的视角，激发人们探索公园的欲 望，并有机会个了解中国的本土植物对美国 以及各地公共空间的影响。

SITE CONTEXT ANALYSIS
Plot D32 is one of five Creative Gardens within the Education and the Future Zone, and as such, EAST AND WEST builds off this unique context in its design and distribution of space types. Curated views of the garden from the Creative Gardens Plaza are developed through the terraced elevation of the Site Character Zones. This allows visitors in this adjacent public space to overlook the varying environments, and encourages an exploration of the garden.
场地分析
D32 地块是“教育与未来地带”中的五个创意 花园之一，在这种独特的背景下，“东方和西 方”在设计和空间选择上的处理上得到了很 好的体现。通过不同“地域特色区”的层级高 度变化，匠心独运地给游览者提供了游览的 独特视角。让游览者通过周边的领略充满变 化的空间，激发人们探索的欲望。

PROPOSED SITE CIRCULATION
The site is designed to integrate with larger expo circulation network where one main entrance and two secondary entrances connect the site with the Creative Gardens Plaza. A maze-like network of paths is created within the garden - some connect between zones and back to the main formalized path, while others lead to viewpoints. Archway openings in the hedge rows create a sense of compression and release as one moves between zones - an experience exacerbated by the differing character of each.
场地流线设计
该设计综合考虑了场地作为博览会整体流线 网络中的一部分，场地通过一个主入口和两 个次入口和创意广场相连接。花园内部创造 了一个迷宫一样的网络－一些连接各个特色 区，一些将人重新引导到主要步道上，还有 一些引导人感受不同的视角。树篱中的一些 拱形开洞营造了各特色空间压抑和舒展的序 列，游客的游览体验通过各个区域的不同特 征而加剧。

PROPOSED SITE FUNCTION
The EAST AND WEST design creates two distinct types of space that allow for varied interaction with the garden - the wide formal walk provides space for active & social group viewing from the perimeter while the curvilinear hedge rows create smaller moments of immersive recluse within. Hedge row height is calibrated at eye level, and the terracing of the Site Character Zones allows for a varied datum within the garden.

PROPOSED SITE HARDSCAPE
Hardscape materials throughout are varied in relationship to the spatial function of smaller areas within the garden. Along the main path, linear concrete pavers draw visitors down the walkway and around the perimeter, while beige decomposed granite forms a more organic medium within the garden. Architecturally cut granite slabs form the garden frame and sit atop a pre-treated corten faced wall. The same granite is used for cloud edging strips that reinforce the separation between bar and cloud planting.

The seatwall and bench elements share a common material palette that both contrasts and complements the hardscape. Both features are comprised of wood slatting that sits atop a pre-treated corten steel base. Wood acts as a transition from the cold and hard ground plane surfacing to the organic nature of the plantings, and allows for a varying and curvilinear seat wall profile at the openings in the hedge rows.

PROPOSED SITE PLANTING
Plants selected for each Site Character Zone are representative of typical plants found in each of the identified hardiness zones shared by China and the United States. Within each zone, three types of formal planting arrangements create a full composition. Visual emphasis is placed one of the tree planting elements, taking precedent from prevalent planting structure within regional ecotypes. Geometric linear ‘bar’ planting forms the underlying structure, and slightly mounded planting ‘clouds’ float above. Small circular sections of accent planting punctuate the space, stimulating the senses and contributing to the differing character between zones.

Archway openings in the hedge rows appear as if the neutral vertical barrier wall was vertically stretched and punctured by a sculpturally offaxis oval. At these moments, the curvilinear hedge movement is echoed in its gracefully waving height above the archways. This vertical stretching of the hedge is mirrored in the depression of the seatwall, where the wood slats top bends downward towards the ground and form the single step tread which connects the upper and lower zone together.

The seatwalls act as both a linear seat extending the length of the garden, as well as the step tread between the differing elevation of adjacent zones. As one element with a dual function, the seatwalls challenge preconceived notions of single use elements as space for sitting or space for walking. The experience of walking through the hedge row archways creates a captivating moment of compression and release and movement across the seatwall contributes to a heightened sensory experience as visitors move from one zone to the next.

PROPOSED SITE DRAINAGE
Each of the four garden zones is treated as an individual micro-watershed. Surface grading within each watershed slopes at a 1% gradient towards the lower zones to the west. Stormwater that doesn’t infiltrate into the groundwater table naturally will be collected in subsurface gravel strips and directed into a level perforated pipe which runs the length of the hedge row. Perforated pipes within each watershed are interconnected by a series of overflows that eventually drain into the Zone 4 Wetland. In major storms, once the high waterlevel is reached, naturally filtered water drains into the exposition regional stormwater system.
排水设计
每一个不同的区域都视为各自不同的微气候 分水岭。表面坡度在各个分水冷中以百分之 一的坡度向西边的低处倾斜。未通过表面渗 透吸收的雨水在上面铺有砾石的水渠中汇 集，疏导到沿着树篱方向的穿孔出水管中。 各个分水岭中的穿孔出水管通过一系列的溢 流系统在内部互相连接，最终流到第四特色 区的湿地。在大量雨水时，当到达最高水位， 经过自然渗透过滤的水会排入区域雨水处理 系统。

Plant species are grouped by similar traits in the garden zones which inherently contributes to a high efficiency irrigation system as the Site Character Zones directly translate into conceptual hydrozones and thus reducing the number of divided irrigation areas. All planting irrigation is achieved with dripline systems and all trees are irrigated with bubblers.

OPINION OF COST
In contrast to plant species and Hardiness Zones, the cost of materials and labor differs greatly between China and the United States. As such, we have prepared an area take-off sheet with rough dimensions for each main element in the proposed garden design. These area take-off values are subject to change throughout the design development phase.
