The “trullo” is a type of conic building made of dry stone traditional of the central-southern region of Puglia. We4Share regains this ancient artefact and she recovers it giving to it, in a modern way, that habit as agglomerate translated both in the residential sphere and in the receptive one. Maybe 5 cones become one set of containers for the ospitality, each with a function, not independent by the others but integral and complementar part.
