IE’s law programs were housed in a new building with a surface area of almost 1,000 m2 located at Príncipe de Vergara 183, opposite the national Auditorium, until late 2012

The campus continued to expand rapidly with the addition of spaces like the first floor of the María de Molina 6 building, to which the IE Learning Team was transferred, and which now houses several key units, including the IE Foundation, Career Management Center, Alumni department, Architecture School, and School of International Relations.
In 2007 the ground floor of Serrano 111 was acquired to provide more office space, along with María de Molina 7, which provided more classrooms and syndicate rooms.
In 2011, a further 500m2 of offices for members of faculty were added on the ground floor of the Álvarez de Baena 4 building.
