E.M.T. headquarters, Madrid, Public transport administrative building in Adelfas, Madrid, Spain.

The E.M.T. headquarters is a building in Adelfas, near the junction of Calle Juan Bosch and Avenida de la Ciudad de Barcelona. Designed by Cano Lasso, it hangs from a bridge structure supported by two concrete cores set asymmetrically and 53 metres apart, with floors suspended by slender tensioned steel bars that free the ground floor.

The building was designed by architectural firm Cano Lasso in 2004 as part of Madrid's effort to modernize its transportation management system. Its completion marked a shift toward centralizing the city's mobility operations under one administrative structure.

The building is the head office of the Empresa Municipal de Transportes de Madrid, the municipal bus company. Its address is on Calle Juan Bosch, near the Avenida de la Ciudad de Barcelona, in the Adelfas neighbourhood. The company runs Madrid's urban bus network, and this site houses its administration.

The building is easily accessible by public transport in a well-developed area of the city. Access is typically restricted since it functions as an administrative facility rather than a public venue.

The building's floors hang from a bridge-like structure supported by two concrete cores placed asymmetrically and 53 metres apart, with slender tensioned steel bars carrying the loads. This leaves the ground floor completely open, a design by the Cano Lasso studio meant to keep the building permeable to its surroundings near the viaduct and green areas.
