In the future, the museum function of the Rector’s Palace and of the neighbouring Providur's Palace will be to accommodate the Heritage Museum / Museum of 2 Palaces which will gather all the departments ofthe current National Museum in Zadar in one place. In the year 2005, with the support of the City of Zadar, a proposal for a conceptual plan of the Heritage Museum was made, whose authors are museologist Tomislav Šola, former Museum Director Hrvoje Perica and the professional staff of the museum, while the program base was developed by the architectural firm "Urbane tehnike/Urban techniques". 

In the year 2010, the preliminary and final project was developed using this base by architects Igor Pedišić and Iva Letilović from the architectural firm "AB forum" in Zadar. With this project, the museum finally received a whole new institutional dimension which will function according to contemporary museum standards and the museum's offer as well asits other accompanying facilities will become the initiator of cultural life int his part of the Peninsula.
