In modern urbanism, hypogee housing is an important trend resource in recent years, but nevertheless the idea of the cities underground is still far away although there are some examples of hypogee dwellings that are less invasive to the surrounding landscape, as they are completely inserted into the land, except for the facade with large stained-glass windows, which there are many examples in Costa Smeralda.
Some think a hypogeal house is cold, dark and damp but with modern construction techniques and a targeted project these houses have countless advantages. The Earth houses are characterized by green roofs covered with grass that also act as excellent thermal and acoustic insulation, without heat loss and exposure to wind and noise and with the enormous advantage of a very high thermal inertia that allows in the particularly hot seasons not to suffer from the heat and in the cold ones to maintain more heat because with the use of a layer of about 30 cm of earth the time needed to heat the ground during the day or cool at night, well superior to that of a roof also well insulated. With this housing choice you can save up to 80% on energy costs compared to a classic house, perceiving in the environments a constant optimum temperature. Finally, maintenance costs are almost zero due to the lack of exposure of the weather.
The villa designed by the group Le robinie RE leaves a lot of freedom to dispose space according to the needs allowing to use zero km materials.
The above results to be only some of the major advantages of the choice of living in a house hypogea, in addition to the insulation do not suffer infiltration of water or heat dispersions allowing a large energy saving. This should be the basic idea for each home, building its own residence as an extension of the landscape and allowing the preservation of the environment instead of exploiting it producing a high standard of living.
