The aim of this paper is to present the current design of the IFMIF-DONES building and plant systems, which comprise the buildings, urbanization and civil works, auxiliary services including electrical, water, gas supply, etc and other non conventional systems as it is the case of the ones dedicated to the radioactive waste treatment. Starting by the context on the IFMIF-DONES facility, the site and the layout implementation are described. Then, this paper explains the framework in which the design origin was conceived and the evolution until reaching the current status, including the systematic works and analysis that has been carried out to take the high level decisions driving the design. The systems are described exposing the function they have to comply within the facility and the solution given by the design, dedicating a deeper section to the main building structures and the solution to its implementation according to the site characterization. As a conclusion, the next steps and foreseen actions for the optimization of the design are drafted.
