That is the most eco-friendly house on the market! Look at the roof for example… its shape like a pergola has a specific function: on the one hand, it takes the archetype of the context, inserting the project in its environment without disrupting the urban rhythm, on the other hand, it won’t accommodate a closed roof that would become a catch-all attic or a wasted space. Another element I found interesting to mention is the structure of the walls… they illuminate the ground floor and they can be optionally removed, tomorrow perhaps working as railings and returning visual link between the two floors.
