D Developing the ability to design virtually and digitally is an interesting challenge for a candidate for Master of Architecture. Knowledge of designing architecture in cyberspace, the process of applying digital virtual design methods, and computing skills of digital design are the activities of this research. The research design reference for the development of this digital virtual design prototype is the Dr Syarief Tayeb Building, Trisakti University. The research objective is to develop a digital virtual design prototype of the building to facilitate virtual exhibition activities for Trisakti University's public relations activities, and it is hoped that it can be rented to the public. Therefore, the title of the thesis is “Development Of Virtual Digital Design Prototype Exhibition Building University Of Trisakti Based On Achten Method.” Meanwhile, the steps of research activities include: analyzing locations and digital virtual design prototypes that exist on several platforms, analyzing virtual exhibition space needs, creating space zoning and programs, analyzing design methods used, analyzing supporting design computing programs, synthesizing virtual exhibition building design program, conducting modelling, simulation, and demonstration techniques to be evaluated by respondents who will evaluate the prototype produced. The critical notes of the respondents became feedback for researchers to continue to improve and perfect it, until a digital virtual design prototype for the Trisakti University Exhibition Building, which was based on android was found.
