Built between 1965 and 1970, the block features alternating horizontal bands of glass and steel. The intersection of the metal beams, as seen in the corners, breaks with absolute geometric angularity. Its designers won several awards for it, including the ADECUAT prize, awarded in 1971 by the Center for Information Technology and Administrative Materials for its total suitability for its specific purposes. The building was an isolated milestone that was only revisited in the run-up to the 1992 Universal Exposition.

The building is listed in the catalog of the Foundation for the Documentation and Conservation of Modern Architecture and Urbanism (DOCOMOMO Ibérico) as a benchmark of modern architecture in the province.

For five decades, it has been the headquarters of Endesa in Seville, where more than a thousand people work every day and which has incorporated various technological advances over the years.

The main building is a detached office building with five floors above ground and a basement. There is another office building attached to the main building (Core Building) with a basement and a ground floor, connected to the main building by walkways. At the entrance to the property, there is another building used for medical services, access control, and mail. The development has landscaped areas and surface parking.

The main building, which dominates the office complex, is constructed with a metal structure and a glass and steel façade. It stands alone on a plot largely covered with vegetation and is complemented by annex buildings at the entrance and to the south of the main building, which are designed in a style that is clearly different from the main building and with a certain neutrality.
