The building with its 116-meter height and 23 floors is the twelfth-tallest in the Spanish capital (counting the CTBA towers).

It is found in and dominates the Plaza de Colón, one of the major commercial centres in Madrid.

[citation needed] The twin buildings are known locally as "El Enchufe" or "The Plug" for the plug-like structure that binds them.

The towers have a suspended structure; the building consists of two pillars together on top of a platform from which hang two large towers with perimeter beams six feet singing with pendulums each floor with cable-stayed steel cables.

Construction commenced with the concrete footings, the two central pillars and the upper platform.
