During the summer, the inclined roof surface of the winter bath functions as an amphitheater facing the pools as well as the park, increasing the connection between the bath and Islands Brygge. Throughout the winter the active zone is mainly under the lifted deck, where the winter bath facilities are placed facing southwest. During the dark months, the winter bath brings life to the area and can be seen as a lantern from both Islands Brygge and Kalvebod Brygge.

BIG proposed leaning the facades of the building outwards until the inclination reaches the average angle of the sun, the facades dodge the sun rays and rest in the shade of the building itself. Due to the relatively high average position of the sun on the sky the total sun exposure can be reduced dramatically at relatively small inclinations. The resulting building volume is a sort of inverted pyramid with the apex buried deep in the desert sand.

The studio’s circular shape dismisses the front side-back side logic of a conventional building and produces a non-hierarchical shape that becomes most appropriate in its context of public space. The circular footprint also maximizes its surrounding public space, allowing the recording studio to become more of a sculpture rather than a building. Because the program of the studio has different requirements for clear heights, the roof elevation is strategically varied to form three peaks. These peaks occur at the live room, artists’ private lounge, and academy studios to provide generous space to its users, creating a playful yet elegant roof line reminiscent of the fluidity of sound. The form is then optimized to produce a series of equal horizontal modules that maintain the readability of the undulating roof edge and efficiency of the building structure.

At street level the floors are shifted backwards and forwards to create green terraces and canopies facing the park. In the middle of the silhouette, where the tower turns residential, the floor plates slide out in a spiraling movement, creating terraces and outdoor space for residents. In its upper section the tower returns to a simple stack of optimized floor plates, completing its twist to rejoin the orientation of the floors below. These inhabitable movements bring human scale from street level into the skyline, embodying the unique character of Frankfurt.

Wrapped with adaptive façade louvers that are oriented according to sun angles and building geometry to minimize solar gain, the façade will become a fingerprint for the building, with a specific imprint that exists only for the O-Tower, and only in Hangzhou. The fingerprint façade will reduce solar gain by up to %, providing significant savings for cooling loads and better thermal comfort for OPPO staff, while at the same time reducing glare, reflectivity and light pollution.
