Mallorca is a luxury house located in Palma de Mallorca. It is a PassivHouse certified construction, distributed on two perfectly functional levels. Ecological materials were used in its design and realization: the wood fiber from Steico was used as walls insulator, floors and roof, as well as mounting support for decorative applied to the outside. An aldehyde-free outer plate was used—DHF, an open diffusion material, perfectly adapted to the climate of Palma. The roof was waterproofed with Rothoblaas certified materials, perfectly sealed membranes, and strips adapted to the mounting area. Aluminum joinery with a sliding roller completes the elegance of the construction.
