In Italy was created a mansion of cactus fibers and solidified volcanic ash
In the province of Lecce appeared an unusual structure. It is the personification of the principle of "architecture without architect".

One of the Italian companies created the house entirely of natural materials – solidified volcanic ash (tuff) and cacti. Panels of balsa wood provide heat and sound insulation. It was used also the local lime and clay. Chief architect Bart Conterio says that fundamentally the builders did not use any chemical solvent and additives.

When designing the building, the architects took into account the direction of the wind and sun. This energy-efficient home has wide walls that can store heat in winter and cool in summer. On the roof there are solar panels. In addition, the house operates a system of recycling of rainwater and used water.
