The concept of working with a sunken ground comes from a mission of fabricating an experience both intimate and intense combined with a strong feeling of harmony with the environment and intimate contemplation. Sunken ground looks at concepts present in Suzhou gardens tradition, such as the rock, the outcrop and the occidental equivalent of the grotto to then travel in space and time to the image of hanging gardens and further on to the concept of a sunken courtyard. The result is a combination both of intense distortions of the ground and an acute sense of three dimensionally, where one feels itself draped by concrete, steel and vegetation, free to explore a thickened version of a microcosm in a series of pocket landscapes for reflection, relaxation and ultimate playfulness.
The first idea is that of the canyon, as a compressed landscape into the space of a corridor. Natural canyons both have the intense spatial quality of the enclosed space, but also inherit the layered characteristics of the geological formation, showing strata, cracks and faults of the matrix rock. We wanted to use this feeling of thickness and formational to explore how architectural elements can fabricate a passage where material, shade and enclosure would dictate the main spatial experience.
As if we were traveling both in space and time, we arrive to the ancient ideas of hanging gardens, where vegetation is viewed from the underneath. This generates a sense of immersion in nature, favoring retreat and reflection within the visitor. The garden also includes sunken gardens which start from a different point, enabling to experience nature from above, but also frame the skyline when we are inside them, closing the look of inside, outside of nature. It is perhaps this constant travel from inside to outside nature which shall let the visitor understand a multilayered relationship to nature and the environment, more in line with concepts of harmony and immediacy.
This effects are also found in nature, where the ground sinks generating a spontaneous multiplication of the surface, vegetated structure and vertical green cover. Natural sinkholes happen in the landscapegenerated new conditions both in terms of scenery but also flora and fauna. This leads to the idea of the captured microcosm, which inspired to design enclosed pots or small landscape ecosystems which, while being inaccessible for the pedestrian, can be contemplated from the outside and where a small choreography of ecological activities can be observed in its complexity and calm evolution. We have looked at existing techniques of green wall and vertical planting combined with ponds, mist generators and scent dispensers. All these shall enable the fabrication of intense ecologies where the dripping of water, the freshness in the air and the subtle movements of fish shall transport the observer to an imagined pocket of alternative natures.
Given that the site has a strong linear character, the first design task is the structuring of two corridors parallel to the main axis. The longer corridor takes the user through a strong experience of being surrounded by concrete, End immersed in a dense vegetation canopy. The canyon effect is achieved thought the incorporation of oversized pots which delineate the path and are both micro gardens or pocket landscapes which can be either entered or observed from the exterior. The second corridor, which stems from the first one, moves from the feeling of being under the Landscape, to that of being on top of the Landscape. In order to do this, a gentle slope places the spectator on a slightly upper position, while the pot is lowered slightly. The combine effect reverts the effect of the main axis in such a way that the hanging gardens have given way to a sunken garden east of the corridor. Both corridors are linked through a series of landscape terraces of different materials, generating a diverse ground which is the ultimate responsible for diversity and variety of experiences.
The pots serve as meandering elements within the larger landscape, a large scale version of traditional ShouZhou garden component of the rock boulder and the miniaturized landscape within the flow of the sea. One can can observe each object but also imagine oneself climbing into it in an act of intimate relationship with nature. Some of the traditional gardens also incorporate an element of circulation within these rocks, so that they become both miniature, but also belvedere and observation. Sunken Ground concept uses these traditions to generate a diverse experience where the levels inside the pots are thought so that visitors can experience the full three dimensionality of the park, climbing to the top of the pot, looking at other pots and the flow of people around. Finally, pavement and plan patterns flow along the entire site, giving it a sense of totality, continuity and ultimate harmony to the park.
Postscript: in the process of the construction, all kinds of emergency situations (such as changes in ground elevation and changes in exit or entrance) but to design comes with lots of fun. In the end, the garden got more and more integrated into the land than previously thought , new ramps and footstep also added more possibly to enrich the space. This is a designer and interactive experience, a multidimensional game.
