The building consists of two parts: an office block, closing a gap on the seafront Paseo Maritimo, and at the back the 114 m high telecommunications tower, fulfilling its dual role as urban landmark and technical installations facility. At the entrance level, the tapering, reinforced concrete cylinder of the tower piercing the horizontal roof is clearly legible. The sculptural effect is further heightened by the curve of the spiral staircase, which continues up the tower in a projecting triangular plan stairwell, giving direction to the building.
