Extension Structure Typology
The expanded structural typology was derived from the architectural concept of space expansion: Parasitic Architecture. Through the case study, spatial expansion methods were classified by type. Among the types, folding, modular and sliding are usually attached to the facade using wood or concrete, expanding the space in a rigid and robust way/manner, but it was difficult to meet the definition of 'Flexibility'. This conclusion led the way to explore the inflatable structure.
