Since the infrastructure is the most important element, the rest of the program is integrated with it as much as possible. In order to create a physical interface, the elevated vacuum tube wraps around itself and descends as a gentle ramp, ending in an airlock that allows for save entry and exits for pods. While the pill shaped loop of the tube forms the exterior façade of the facility, the support structure gets extended towards the interior as a sequence of concrete frames with fileted corners for lateral support.

The panoramic gallery is a large open space suitable for sculptures and large installations, with the ability to be subdivided for special occasions and events. On the north end, a full-height glass wall offering panoramic views to the pulp mill and river tapers while curving upwards to form a cm-wide strip of skylight. A café is situated at this end of the gallery, where guests can enjoy snacks while taking in the view of the historic pulp mill and surrounding landscape. During the summer months, the café service area spills onto the plateau just outside.

The building comprised of timber in its upper structures, bridges and slabs features a long and slim footprint covering an area of ca. , m. SBC makes full use of the allowed maximum building height of . m across seven floors, and is based on an ideal office bar typology measuring m in width. Instead of one single zig-zag volume, as envisioned in the masterplan, BIG’s design consists of two stacked and rotated zig-zagging bars.

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.

The roofscape is one of the most important components that shapes the spirit of the Cloud Valley. It allows for an abundance of nature to co-exist with the office programs, thus preserving the wild landscape experience that’s traditionally difficult to access within the city limits. The green roof also embodies an ecological cohesive coexistence between human, nature, climate, and technology. To display the ultimate gesture of nature meeting technology, the green roof carpet shaping the valley and the mountain turns into the largest digital display in China at night.
