5、a 4000 sqm Greenhouse and a 3500 sqm Gate Building sitting in a 37 ha landscape that will house the International Horticultural Expo and a park for Xian City as legacy.The Expo will open in 2011,receiving approximately 200,000 visitors a day.Flowing Gardens unfolds many sinuous paths,creating a netw
6、ork of intermingling circulation,landscape and water.The given topography and its existing slopes were used to draw out the paths in a way similar to how roads ribbon around a mountain,negotiating steepness with gradients.These paths vary in width ranging from main walkways and arteries to towpaths.
7、The patches between these paths become the zones for various planting types and wetland areas.The three projected buildings,located at the intersections of the major pathways are developed as the nodal articulation and intensification of the landscape.LandscapeThe project proposes a hybrid of both n

34、them up to+7.00 m the bridge offers vantage points from where to gain an overview of the different zones of the Expo ahead.Functionally,the bridge needs to have two lanes for incoming and outgoing traffic.Naturally,these flows are very uneven and change greatly between the beginning and end of the d
35、ay.Taking the idea from the London Underground escalators we devised the bridge to have three lanes,where the middle lane switches from the incoming direction in the morning to outgoing later in the day.The three bands read as interwoven braids,and together with a trellis roof structure give the app

37、 green roof,and suggesting to distant onlookers the theme of the Expo.For this lightweight roof,we developed together with Arup an innovative tensegrity structure that appears as beams seemingly free-floating in space.Gate building renderGate building sectionsGate building bird viewGate building bir

40、hillside.One enters the building through a prolonged cut,literally being scooped up by the ground then emerging within a light-filled cavernous reception space.From here the visitor transgresses along a tessellated mesh of paths through three different climatic zones with corresponding plant environ
41、ments.The greenhouse has a horseshoe plan creating one loop that changes radically in section to accommodate a sequence of different planting and spatial conditions.With the ground inside and outside gradually changing in relation to each other,the visitor is experiencing sequences of visual enclosu
42、re alternating with long vistas out and across.The horseshoe shape generates an inner courtyard,making the outside space the natural centre of the building.This courtyard becomes dissected by two paths that continue to slope up to pass over the roof,at the apex of the greenhouse and further into the
43、 landscape.This creates a three-dimensional interweaving of interior and exterior circulation,of building and landscape.The first environment that visitors encounter is the arctic zone.It sits relatively low inside the ground and is directed towards the north.The paths are sunken in further so that
44、visitors eyes are closer to the small and delicate plant details.After this the building turns a corner and becomes the rare plants zone.This has been laid out to contain a finer tessellation of plant beds and paths.From here visitors walk up to the highest point in the building from where they ente
