Synaesthesis is derived from "synaesthesia" and "thesis." Synaesthesia is an automatic and spontaneous experience where senses blend, such as seeing colors with music or tasting flavors with shapes. Combined with "thesis," it describes the integration of multiple senses in architecture. This concept creates spaces that enhance the overall perception and engagement of individuals, blurring boundaries between sensory modalities for a multi-sensory experience.

The concept of synaesthesis in architecture invites us to consider how spaces can be designed to engage all the senses, fostering a deeper connection between individuals and their surroundings. It allows for the exploration of innovative design strategies that evoke emotional responses, stimulate creativity, and promote a sense of well-being.
