Casa Buna, a model house with four duplex apartments in Romania, is the result of a partnership between the NGO Habitat for Humanity and the ArcelorMittal Foundation.

Its structure consists of prefabricated elements of light steel frames, ensuring easy, fast and low price construction. In addition, Casa Buna is extremely energy efficient and complies with the standards for low consumption buildings.

A two-floor house can accommodate four families. The steel frame structure is made of cold-formed profiles. The whole system can be assembled by unskilled volunteers and has at least a 20-year life span. At the same time, the “Casa Buna” prototype is engineered in accordance with the European and Romanian construction codes.
