The aim of the project is to design and produce an element, called “prothesis”, capable of binding itself in a symbiotic relationship with the space and the elements that inhabit it, furniture and people. The ability to change one’s form and purpose allows for a consequent transformation of the elements with which it comes into contact, resulting in an evolution of these towards more favourable characteristics and conditions such as versatility, adaptability and increasing the possibilities of use. The prosthesis, lowered into the space, changes the relationship between space, furniture and person, giving life to a new human environment.
