When we heard Retro design, people will think about the fashion, music, poster, style and trend of the 1940s to1980s. The trend retro-futurism, however, is entirely different. It is a trend that was created by writers, artists and film directors in the past and is closely related to science fiction. This research concentrates on investigating the characteristics of retro-futurism and how it can be used to incorporate its features into building design for 3D animation. An exploratory method was used to analyse the architectural design of the past. The gathered information could give some insights and understanding of what retro-futurism is and the reason behind why the architectural design in the previous era was created that way. The process and challenges of implementing retro-futurism visual style are also discussed. As the result of the collected data, developing a design with the aesthetic of retro-futurism become more accessible and well-planned.Keyword: Animation, Retro-futurism, 3D modelling, Art movement, Art period, Exploratory method
