The firm James&Mau Arquitectura designed an innovative home in the picturesque Tarragona Province, Spain. The house was built by Infinski and instead of using shipping containers as the main building blocks, the builders chose to use 4 prefabricated metal modules made of Corten Steel. The finished home is called Mint House and comes with a number of sustainable features.

The structure of the 100-square-meter house is made from 3 modules (ISO transport) of Corten Steel. The walls are insulated with an insulation layer made of sheep wool and cellulose panels. For heating the home is equipped with Biomass heating and solar panels, while the eco-friendly insulation and sustainable paneling also means that the house has a minimal amount of thermal heat gain. According to the builders, the home enjoys 60% less energy consumption when compared to a traditional home.


Another innovative feature of Mint House are the shutters, which are perforated and decorated with mint leaf shapes. These shutters function as solar protectors allowing air and light to pass through them into the house, while keeping heat out.

Mint House is used as a weekend retreat by the owners, and was designed so as to fit seamlessly into the surrounding natural environment. It was also designed as a sort of “living box” which can be “opened”, “closed”, “switched on,” “heated”, and “cooled down” efficiently, easily and quickly. The home was also designed so that the transition from the interior to the exterior is as seamless as possible.
