Design a structure completely based on SIP panels (structural insulated panels), supported on a grid of foundations that intervene minimally in the existing terrain. three-dimensional modules, made up of floor, walls and roof panels. The modules were designed in two widths and two heights, which in their combination and association constitute the rooms of the house. The dimensions used to configure the modules correspond to the manufacturing dimensions of the panels, maximizing the material and reducing losses during construction. The resulting roof, with alternating heights, generates light entries oriented to the north in most rooms.
