The house has a construction based on the technique of rammed earth, with natural ventilation and large windows in every room. The slab structure is made of beams of wood to avoid electromagnetic meshes produced by rebar. The architecture is circular and oriented according to the feng shui system laws.

In terms of landscaping and for better use of the entire area, terraces were constructed and several fruit trees planted with a drip irrigation system already in place. There is also an area of an organic garden, designed according to permaculture principles. A system of harvesting rainwater in tanks was put in place, and it can be used to power the system of drip irrigation of installed. The irrigation system is also fed by water from the well and distribution works by gravity. The wastewater is treated and reused through an ecological pit (has several banana trees to dry the water in a faster way).

This space can be used as a greenhouse, where can be made a vegetable garden. There is also a protected area, where there is already a hive of bees with a production of 40 kg of honey per year just taking honey once a year, but it is possible to take it 2 times a year.
