Rio City Tower is not only a tower. It‘s self-awareness is to be a connector not a single landmark. The concept of RCT though, is not to compete with the multiplicity of spectacular and world famous icons of Rio de Janeiro but to become a joined symbol of the quality of a multi cultural contemporary and global acting metropolis.
Position and structural geometry are creating a confluence point of trajectories in the Rio bay and reinforce the existing urban fabric. -Rio‘s new gate emerges. With its lush hills and exuberant natural surroundings and urban structure, Rio de Janeiro appears to be an interface of cultural and natural datum. RCT is fusing these mayor parameters by self evidently merging its shape and structure with the natural topography of the surroundings but remaining its autonomy by reflecting in program and function the faciality and man-made character of the prosperous and vibrant metropolis.
Geometry and design are generated by connecting eight elementary urban attractors of the Rio bay and projecting them on the island of Cotunduba. These geometric trajectories are transformed into a loop above the summit of Cotunduba and creating the mayor and clearly visible volume of RCT. Emerging structure and shape of RCT appear as natural expansion, of both, the contextual topography of Rio de Janeiro and its artificial urban fabric. Due to its natural geometry, RCT appears to be a logical amplification of the island of Cotunduba rather than an artificial addition. It growth on four mayor legs up to 160 meters of absolute altitude, reaching a total height of 100 meters above the summit of the island to be clearly visible from all parts of Rio de Janeiro and providing spectacular views towards the city. Up to the first platform, on level-2, 25 meters above ground it is possible to use three of the structural legs for climbing. On the forth leg, towards the ocean, a gyro slide accelerates visitors to maximum enjoyment. The four structural loops creating the transparent volume of RCT are containing the programmatic features in boxes aligned to and accessible through a spiraling ramp that provides continuously changing panoramic views over the bay of Rio de Janeiro. At night the program-boxes and structural loops will be lid in kaleidoscopic colors, which through the lamella gills of RCT, create an image of ephemeral beauty, alike a fluorescent and transparent abyssal organism.
