If there is no doubt that ‘size matters’, and that scale is one of the main factors in architecture, it is also true that the propositional interest of a building is independent from its size. To support this argument, the sixteen houses selected here represent the very different strategies and dimensions that can address domestic space. With size as organising element, the issue starts with a minimum shelter of less than 30 square meters in southern Australia, and includes examples that range from careful interventions on heritage to daring typological experiments, ending at the Chilean Andes with a large house-studio of over 2,000 square meters.
