In 1995, the Mauritshuis was established as a non-profit foundation. The foundation set up at that time took charge of both the building and the collection, which it was given on long-term loan. This building, which is the property of the state, continues to be rented by the museum. In 2007, the museum announced its desire to expand. Within three years the definitive design was presented. The museum would occupy a part of the nearby Sociëteit de Witte building. The two buildings would be connected via a tunnel, running underneath the Korte Vijverberg.
