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 museum is comprised of a series of generic gallery spaces where, due to the curved form of the glass windows, the variety of daylight entering the museum creates three distinctive galleries. Stacked vertical, dark galleries with artificial lighting are found to the south, and a large horizontal, naturally-lit gallery with panoramic views is located on the north side. In between these spaces is the sculptural gesture, creating a twisted sliver of roof light.

The façade is composed almost entirely of , prefabricated concrete panels interspersed with windows of various sizes to control the amount of light entering inside and to create a sense of transparency. The concrete slabs, which weigh up to . tons, are sandblasted to expose its raw qualities and to texture the surface with the local sandstone of Bordeaux. Yellow granules for brightness and warmth radiate the building in the sun and help integrate MÉCA as a familiar yet new vernacular sight to the city.

BIG’s design ensures that the tower apartments have optimal conditions towards sun and views. The bar units are given value through their spectacular views and direct access to the roofscapes, activating the outdoor realm. The exterior facades are developed to correspond to the different orientations and solar conditions, creating a diverse façade which varies from the viewer’s vantage point and the position of the sun.

When asked to design an apartment block next to a parking garage, BIG saw an opportunity to explore a new form of symbiotic urbanism. Rather than placing a traditional slab of apartments next to a block of cars, BIG proposed mixing the two and exploiting their differences as a strength rather than a weakness: cars need large floor plates and good proximity to the street, while houses want sunlight and views. As a result, the parking is turned into a podium for the building&#;s homes that form a stepping landscape of houses with gardens.
