Torres Atrio, Office complex in Bogotá, Colombia

Torres Atrio is a two-tower complex under construction at Caracas Avenue and El Dorado Avenue in Bogotá. The South Tower is planned at 67 floors and 268 m, the North Tower at 44 floors and 200 m, built mainly in glass and steel. In the photograph the shorter tower is dark gray with a dense window grid, while the taller one is clad in blue reflective glass with orange-brown mullions and a slanted lower section.

In 2007 the Chaid-Neme Group bought the Caracas Avenue and El Dorado Avenue lot, once owned by Luis Carlos Sarmiento Angulo, and later added the Gonzalo Jiménez de Quesada Convention Center and its parking lot, forming a 17,000 m² site. Foundation work began on 19 January 2015; on 29 July 2016 a 2,400 m², 3 m thick foundation slab was poured in 38 continuous hours, the largest single concrete pour then recorded in Colombia. The complex remains under construction.

The name Atrio refers to the central pedestrian and commercial promenade of 10,000 m² planned over the former Gonzalo Jiménez de Quesada Convention Center. The complex is designed for offices, retail and a hotel, and is meant to link into an environmental corridor running from the national park through Independence and Renaissance parks to Simón Bolívar Metropolitan Park.

The site lies at the northeastern corner of Caracas Avenue and El Dorado Avenue, in the International Center. The complex is reached through a 10,000 m² pedestrian and commercial promenade planned over the former convention center square. The North Tower is the phase under construction, with 50,000 m² of offices, 4,600 m² of public services and 1,800 m² of retail.

The project targets LEED Gold certification under the Core and Shell category, not a completed award. Its design uses daylight studies and ventilation planning to cut environmental impact and running costs. The glass facade alone equals 15 football fields in area, and 21,000 tonnes of steel go into the structure.
