Green Nest House, where everything flows. Three interconnected rooms that will make your day to day easier and more pleasant. Dream of its open and wide spaces that will allow you to bring the outdoors in and feel that you are an extension of Nature.

Green Nest House conceives its houses as environments that guarantee maximum comfort thanks to a well-planned design and a digital infrastructure that meets, in an efficient and sustainable way, each of your needs.

A 100% sustainable house. Green Nest House generates ideal self-sufficient environments to guarantee you a life of sustainable quality, thanks to its recyclable construction, the selection of the best ecological materials and the creation of healthy spaces that provide unique life experiences. By building your Green Nest House, you will improve your health and quality of life and, at the same time, you will contribute to the care of the planet.

A 100% healthy house. Currently most of the materials used in traditional construction contain toxic substances for people. Green Nest House ensures the traceability of all the materials used to guarantee the highest quality of the indoor environment. The construction system of the Green Nest House does not use materials that are harmful to one’s health.

  • Energy: Photovoltaic Solar Panel that produces electrical energy on site and reduces fossil energy consumption.
  • Glass: Maximum transparency and comfort. A technological glass with high thermal and lighting performance and with a high content of recycled material.
