CASA G project includes the renovation and energy redevelopment of a residential building, located in Moneglia in Liguria, which dates late nineteenth century. The space is distributed on two levels and the local stone masonry has been maintained. The range of clay-based and rice husk plaster RH420 creates colour contrasts in harmony with the surrounding nature. Externally, the use of natural lime, which contributes to the perfect breathability of the wall surface, gives the feeling of integrity to the landscape. The result of this renovation is evident on such works of redevelopment that have enriched the aesthetic impact of the internal spaces and the external side related to the garden that surrounds the house.
