Due to the unique character of Singapore’s urbanism &#; both very dense and verdant &#; BIG pursued the design challenge as a vertical exploration of tropical urbanism, reinforcing Singapore’s reputation as a garden city. The building’s recognizable exterior façade consists of vertical elements that are pulled apart to allow glimpses into the green oases blooming from the base, core and rooftop. A dynamic interplay of orthogonal lines and lush greenery presents itself in the contrasting textures of steel and glass, interweaved with tropical vegetation.

Like a seismic fault line, the architectural crusts of planet earth are lifted and mingled to form an underlying continuous space of caves and niches, lookouts and overhangs. Rather than a single perimeter delineating an interior and an exterior, the façade is conceived as a sinuous membrane meandering across the site, delineating interior spaces and exterior gardens in a seamless continuum oscillating between the city and the park.

Cloud Valley takes its inspiration from the natural Wulong Karst in the Chongqing Wulong National Park, where valleys and mountain form stunning connections between the earth and the sky. BIG’s proposal for Cloud Valley is conceived as two plots along Xinzhou Avenue and Gaoxin Avenue, that mimic each other’s opposites. There is the Mountain, which forms a striking landmark in the area that gives shelter to a protected network of courtyards filled with inviting public functions. Then there is the Valley, which offers the largest publicly accessible green rooftops in China for open-air events. Below the roofscape, the building opens up to the surrounding public to invite visitors into this new neighborhood.

Elements often repeat and continue from one side of the space to another to reinforce the idea of space continuity: a grid of Bulb fiction pendants designed by BIG Product across the north side, a grid of Artemide Alphabet of Light  lights around columns throughout the space & larger pill shaped lights across all meeting rooms. Each conference room is furnished with Scoop chairs designed by BIG for Halle. The color of the chairs designates the room.

The prefabricated elements are stacked in a way that allows every second module an extra meter of room height. By gently adjusting the modules, the living areas open more towards the courtyard while curving the linear block away from the street to expand the sidewalk into a public square. The resulting checkered pattern becomes the trademark of the building. Economical constraints often lead to scarcity — at Dortheavej, BIG managed to create added value for the individual as well as the community.
