Torre Virreyes, Skyscraper on Paseo de la Reforma, Lomas de Chapultepec, Mexico City, Mexico.

Torre Virreyes is a 121-metre office tower on Paseo de la Reforma in Lomas de Chapultepec, designed by Teodoro González de León and completed in 2015. Its irregular prism widens toward the top, creating a cantilever over a base that incorporates part of Vladimir Kaspé's 1948 Súper Servicio Lomas. The facade combines exposed concrete, structural steel and glass, with concrete fins that shift in appearance as you move around it.

The plot was occupied from 1948 by the Súper Servicio Lomas, a service station, car dealership and restaurant complex designed by Vladimir Kaspé. Grupo Danhos bought the land in the late 2000s; after debate over the modernist building's value, the design by Teodoro González de León kept part of it, and the tower was completed in 2015.

At the main entrance stand "Los Gigantes de Piedra", sculptures by the Swiss artist Ugo Rondinone, installed as part of the development's art programme. The complex also keeps part of the former Súper Servicio Lomas, a 1948 work by Vladimir Kaspé, so two eras of Mexican architecture share one site.

The tower stands on Paseo de la Reforma at the western edge of Bosque de Chapultepec, in Lomas de Chapultepec, Miguel Hidalgo. Its lower levels hold shops, restaurants and a food court, and the complex includes an auditorium, a multi-purpose room and a museum. The entrance plaza displays Ugo Rondinone's stone sculptures, Los Gigantes de Piedra.

The tower's footprint widens as it rises, producing a large cantilever over the base; Arup worked with Teodoro González de León from the first design stages so the structure could carry this overhang without changing the architectural concept. The concrete fins on the facade shift the building's appearance depending on the viewing angle and limit solar gain.
