Domestic astronomy is the prototype of an apartment where you no longer occupy a surface, you occupy an atmosphere. As they leave the floor, the functions and furnishings rise: they spread and evaporate in the atmosphere of the apartment, and they stabilize at certain temperatures determined by the body, clothing and activity. Our proposal is to make allowances for these physical differences in the distribution of temperature in the space and to exploit them by changing the way of life; to replace a horizontal way of living with a vertical one where we can occupy different heat zones, different layers, different heights. And thus to create a global ecosystem like a kind of astronomy in the home, where combinations of temperature, lights, time and place are reconfigured.
