"Hospitium" as a suggestion consists the drawing product application of a spatial model whose background and theoretical references are in the structure and convention of the modern cities as discussed above. Better than defining it as a building is to define it as a total habitation of multiple activities and uses whose structure is based in a system. That system has not a specific and final form but constitutes a continuously changeable spatial system and a sum of heterogeneous and discontinuous rooms that is specified by the simultaneous relations of actions, events and experiences to many levels emphasizing and giving practical importance to concepts such as multifunctional and mixing of uses and identities.
   Key for the perusal of «Hospitium» is the flexibility. The forms are incomplete, open, non hierarchical, with his inside being integrated or confused with the outside, disassembling the interior with the exterior limits. The form that is created every time will be a result of composition and articulation of factors, facts and conditions that will be supplied by the same social forms with the ability of not being confined and to translate the data inside flexible programmes which are not confined to former logics but on the contrary they set them aside even if finally they end into a total negation of the walled environment. The ability itself of the system allows the sudden changes of the level.
