Architects working in this field work on projects based on three main factors: high aesthetic impact, low environmental impact, and improved livability. To achieve these goals, they carefully combine natural elements and the context of the building or home, aiming to achieve optimal thermal insulation, ventilation, and dehumidification.

To this end, the choice of materials is particularly important: they must meet certain criteria, such as low environmental impact, high performance, and low cost. Conventional paints, enamels, glues, and chemical paints are prohibited. Yes to natural compounds and paints, and to materials such as stone, wood, plaster, and lime.

Insulating materials, concrete floors, and all potentially air-polluting elements are also banned. To this end, new ventilation systems are continually being developed to minimize stale air, which is harmful to health. For the same reasons, the choice of furniture and its materials must be carefully considered.
