Energy-intensive building

The building is located in an area of residential expansion of Rovello Porro (CO) and is made of wood frame construction. To express request of the customer has opted for the use of this constructive system for presenting various advantages such as: the speed of the timing of putting in work (with the consequent decrease of the problems generated by the traditional construction site), the high energy performance (also taken place by means of dedicated plant design it), the high cost control (given the increased emphasis in the design phase, the typical practice of prefabrication).
