Part of the complex of new facilities of the Fira de Barcelona, this 110-meter tower accommodates a hotel program, distributing its 26,000 square meters of floor space in two volumes – separated by an open atrium partly colonized by plants – reached by way of a shared hub of five elevators, two of them panoramic. Reducing the tower’s scheme of very small bays (little more than 10 meters) made it possible to develop a frame with conventional structural frames made of pillars and slabs of reinforced concrete which are further rigidified with screens placed in the gaps between rooms. On the outside, the predictable fenestration of rooms is broken by an ornamental stroke that alters how the scale of the project is perceived. Windows give way to organic apertures that merge with the plant patterns screen-printed on the white glass on the south, east, and west, and matte glass on the north.
