Fluid habitat is a metabolic system capable of adapting its geometry through the application of a phase changing material in the built environment. It is a concept of floating housing, a structure that is attached to existing buildings, working with their infrastructure. It redefines and reconfigures the built space. Through the application of paraffin wax, the building’s envelope is capable of reshaping itself according to the position of the sun, the amount of heat required and the sound levels desired.
