The King Abdullah Financial District is a new 55-million-square-foot mixed-use urban community in Riyadh. Among its public buildings under construction is FXFOWLE Architects’ Museum of the Built Environment (MOBE), which explores the role of social, economic, and environmental issues in the development of the Kingdom of Saudi Arabia and the larger region. The museum will exhibit works related to the history of the arts and architecture on the Arabian peninsula, as well as document trends in sustainable thinking and their role in the future of the built environment.
