Vezzano is a small village of 400 inhabitants on the slopes of Monte Sole, the sunniest side of the middle and lower Val Venosta in South Tyrol. Here, in about two months, it was possible to create a multi-family house in solid wood, a real living organism without glues and metal parts, energetically autonomous, which interpreted the needs of the clients in symbiosis with the language of nature. The wood used has a particular history: Holzius, who built the house on a project by the architect Cosimo Modica, uses lunar wood, that is, cut during the waning moon phases in which the sap enters the resting phase allowing the material to acquire additional qualities of stability, durability and hardness.
The design took into consideration key elements of bio-architecture, including the position of the house on the side of the hill resolved with the creation, in place of the traditional basement with exposed foundations, of a solid wood ceiling ventilated on the back to guarantee the air circulation to prevent the onset of humidity. The assembly team worked on the shell of the house, completely covering it in untreated solid wood. In particular, the external solid wood walls, made up of three layers (180 mm) with wood fiber insulation, intersect with plaster-coated sections, while those inside are covered with clay plaster for additional warmth and safety.
The living area of 220 square meters has been divided into two residential units with the lower floor set up for the use of parents and the upper one for the use of children with spaces defined for each. “The home atmosphere is pleasant and instills a feeling of well-being never experienced before. Compared to the brick house where we lived for 25 years, the climate inside is unique, we do not suffer from the cold even though we live at the same temperatures, and I seem to notice that even the plants grow better ", confides the owner.
Another distinctive element of the project is its energy autonomy which allows the house to produce the needs it needs thanks to the installation of a photovoltaic system that supplies electricity to the water-air heat pump that runs through the underfloor heating system. generating heat inside the building. For the irrigation of the garden, on the other hand, a 5,000-liter rainwater tank in the lawn is used.
