It is located in a real property at the Collserola Mountain called "La Esperança", in the old municipality of San Gervasi de Casoles, presently depending of Barcelona.

This unique site consists of three clearly defined parts. The first one, built on an existing construction, was committed, following a careful restoration, to offices for the management and administration of the Judicial School, as well as the bookstore. The second one, a new building, hosts the classrooms and the auditorium. The third one, also new, is reserved for common services and serves as a link between the former two.

The estate is owned to the Catalan Government, which assigned its rights of use to the General Administration of the State to with a view to host the Judicial School of the General Council of the Judiciary during thirty year.
