There are a small number of optimum houses: the longhouse (cold rural family), the manor-house(porches, large farm, multi-generation), the courtyard house(suburban multi-generation), the townhouse with shared courtyard (mult-generation), the paris-house (apartments) with shared courtyard and boulevards.
