The Infiniski Menta House is no ordinary place to live. The 100 m2 house in Reus, Spain is literally a living box that can be opened, closed, switched on, heated, or cooled down, all in an efficient and simple manner. The house has a cubic shape and consists of shutters with perforated panels of corten steel in the shape of mint leaves. The shutters give a nice illuminated touch to both the interior and the exterior while also working as solar protectors that allow air and light to pass through. The house was formed using a bioclimatic architecture, allowing it to adapt to its energetic needs, including natural ventilation, passive solar design, an intelligent façade system, and natural shades. The design called for eco-friendly materials to form the basic layers, including insulating sheep wool and cellulose panels. The house has an open kitchen, two rooms, and a common bathroom, with energy efficiency as one of the key things making the residence so delightful.
