There was a question, what do we need the walls and outer sheath of a house for anyway? What is it there for? Does it have to be made out of solid materials, bricks, stone or wood? Do we have to make always in the same manner? Or can it serve another purposes than we thought. In fact the aspects of statics, structural analysis or load distribution can be handled by the structure of a house entirely without the outer walls and therefore to go away from a solid outer walls to attempt a new sort of skin that offers different capabilities. Can move, can be opened and closed instantly, can do things that fixed rigid structure couldn’t do, can be lighter, be out of materials that require less energy to make them. That is something that Cutis project brings as a question. In the search for the answers has come up a concept of an house using intelligent double membrane facade and steel skeleton named Cutis. Cutis is a medical term for the epidermis and the dermis, the two upper layers of our skin. Using similar principle of two layered skin for a house is the idea behind this project. Imagine an object sheathed with two outer layers which cooperates and interacts to provide the best possible indoor environment. To achieve this goal Cutis applies nature inspiration and advanced modern materials. The outer layer can be opened and closed in order to be more adaptable and quickly adjust to weather conditions. The air cavity between the two layers works both as a thermal accumulator and with the HVAC system also as a heating element.
