STATUS: construction phase
Filmic urban space; around, over and through multifaceted spatial layers, is one of the central aims of this Hybrid Building complex with over 700 apartments sited adjacent to the old city wall of Beijing. The aspiration of the developer Modern Group is for an ultra-modern expression of 21st Century ecological urban living, in this 220,000 sq. m. project.
Current development in Beijing is almost entirely “object buildings” and free standing towers. This “city within a city” envisions urban space as the central aim—as well as all the activities and programs that can support the daily life of over 2500 inhabitants: café’s, delis, laundry, dry cleaners, florists etc, line the main public passages. The eight towers are linked at the twentieth floor by a ring of cafes and services.
The polychrome architecture of Ancient China here inspires a new phenomenal dimension especially inscribing the “spatiality of the night”. The undersides of the cantilevered portions are colored membranes in night light glow. Misting fountains from the water retention basin activate the night light in colorful clouds, while the floating Cineplex centerpiece has partial images of its ongoing films projected on its undersides and reflected in the water.
Focused on the experience of passage of the body through spaces, the towers are organized to take movement, timing and sequence into consideration. The point of view changes with a slight ramp up, a slow right turn. The elevator displaces like a “jump cut” to another series of passages on a higher level, which pan across exhilarating peripheral views.
The encircled towers express a collective aspiration; rather than towers as isolated objects or private islands in an increasingly privatized city.....the hope of a new type of collective 21stcentury space in the air is inscribed. Programmatically this loop aspires to be semi-lattice-like rather than simplistically linear. We have an initial series of programs. However we hope the sky-loop and the base-loop will constantly generate random relationships, just as a modern city does.
Mass housing in china has historically been standardized and repetitive. Our hope is to break the pattern; this new vertical urban sector aspires to individuation in urban living. Hundreds of different apartment layouts in a huge variety of types will be available among the 728 living spaces constructed here. And it should be emphasized, that even if this would lead to a commercial advantage, the reason for this individuation is philosophical as well.
Digitally driven prefabricated construction of the exterior structure of the eight towers allows for “beamless” ceilings. Every apartment has two exposures with no interior hallways. Principles of Feng-Shui are followed throughout the complex, which is aimed at sustainability “LEED Gold” rating.
Garden of Mounds
Re-using the earth excavated from the new construction, five landscape mounds are formed, each one fusing with recreational functions to be enjoyed by all. The new park is semi-public space while the use of the integrated functions is electronically controlled by the residents’ cards.

Adjacent to and integrated with the kindergarten, this mound had a tunnel through it and is fenced in for child security.
Functions: Swings and Slides
Sand Box Play Area

Sky lounge a unique ring of bridges and public spaces at the 12-18th floor level, accessible from 3 designated lobbies and express elevators, link all 8 residential towers together. The sky lounge programs include bar, restaurant, gallery, bookstore, lounge, swimming pool, sauna, gym, spa, and shops.
Structural systems: .The main structural system for the eight towers is cast-in-place concrete. The concrete design of the building envelope includes diagonals to optimize load distribution to the ground floor level and below. In addition to the exterior concrete moment frames, concrete encased steel bracing diagonals insure required stiffness for the upper, cantilevered portions of the buildings. A cruciform plan of the shear walls is included to increase global stiffness for overturning moments as well as resisting large earthquake inertial forces
The structural framing of the bridge consists of a Pratt truss system. At the connection to the towers, base isolator is utilized to allow independent movement.
Mechanical Systems: Ground Source Heat Pump system, one of the largest in residential construction, provides most of the heating and cooling loads. It is comprised of 600 geothermal well, 100 meters deep underneath the basement foundation.
Radiant cooling and heating, displacement ventilation, exterior window shade, localized FCU and humidification, and high performance exterior building envelope together provides minimized energy consumption and maximized comfort for apartment units.
Gray water from all apartment units are recycled and reused for irrigation, toilet flushing and pond water rebalancing.
Materials: sanded and anodized aluminum panels as main cladding material
Structural glazed curtain wall with Low-E coated IGU
Painted and Perforated aluminum panels
Honed granite paving on Plaza
Exterior wood deck at pond and roof top gardens
