Condominio 25 Verde is a residential building in Turin. It represents the first experiment in eco-sustainable bio-architecture in the city designed by Luciano Pia. If as a child you dreamed of living in a tree house, if you think that living in the city but completely immersed by the greenery of nature is not possible, it is because you may not know about the existence of 25 Verde, a real inhabitable forest, in the heart of Turin.The steel structures are reminiscent of trees, with their mighty trunks and branches, reaching to balconies, windows and terraces.Large steel pots arranged along the facades house lush plants.
