The Gare du Pont de Bondy continues the Parisian tradition of utilizing bridges as social spaces and cultural landmarks. Located at the encounter between the communities of Bondy, Bobigny and Noisy-le-Sec, the station is conceived as both bridge and tunnel wrapped around a giant atrium, connecting the riverbank to the train landing. The deepest train tunnels will now open directly to the Parisian sky, and all three surrounding neighborhoods will be united in a single inclusive loop – a new architectural hybrid of urban infrastructure and social space.

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.

The building’s structure is designed as a stack of two volumes, or rectangle ‘blocks’ &#; two per floor &#; with each pair rotated degrees from the floor below. On the interior, each individual volume is expressed as a rectangular wood-clad truss on the long edges, and as a floor-to-ceiling glass facade on the shorter sides. The continual rotation of each floor creates a sky-lit, central atrium at the heart of the building that provides direct views into classrooms and research spaces from all levels.

A series of triple-height void spaces and interconnected terraces under the sloping O roof surface will provide visual and physical connectivity between floors, and the opportunity to introduce biophilic social spaces and shortcuts for all OPPO staff. These spaces will bring human interaction out to the facades, where staff can enjoy views out while populating and activating the skyline of the city.

The site is laid out as a grid of , x , meter squares, creating one continuous pixelated surface. As a topographic map the surface is morphed to form a terraced landscape of towers, accommodating . m housing, hotel, offices and shops. The project becomes an accumulation of individual niches and outdoor spaces forming a collective organic architecture &#;  a Scandinavian high rise typology incorporating the human scale, the rationality and flexibility of Danish building tradition.
