The possibilities to build a home can be limited due to both restrictions on the surface available, as well as on normative and economic restrictions. The diversity in the topology of the projects presented reflects the possibilities that can be developed in order to achieve this objective. And although they can vary regarding the climate and topography of their location, they all share a common theme: the design of homes with a tight budget. Whether these are completely or partially prefabricated houses, extensions, houses made of containers or even a studio or a foster house for children.
