Collages are generally known as mixed media techniques that can be used as representational media to express an idea that represents a concept. In the context of architecture, to be able to communicate an idea or concept idea into a visual form, a media is needed as a medium to convey the idea of the table designer, so that the client can understand the idea. In the process of designing, the role of collage as a visual representation medium can make collage one of the potential methods to represent an architect's idea by combining fragments of design elements to produce new work with new meaning. Collage can initiate and estimate the creation of architectural space by representing the meaning of an object into space (Socio, 2006; Martin, 2007). The meaning of a design has the potential to add value to the existence of a building because with the meaning of the design; buildings can develop into a cultural heritage building that is not lost to the times. By using the collage method in the design process, the meaning of a building can be arranged so that the building can maintain its existence. However, collage has not been widely used as a method that is considered the potential in the architectural design process. So, in this paper, the author aims to see the potential of collage as a method used in the design process, which is then proven by studying the Villa Isola cultural heritage building. The results of observations show that in the design process of Villa Isola, there is a compilation of contextual elements that form the design meaning by the collage method so that the building can still retain its meaning.
