We are a network, an ecosystem of interconnected environmental co-living housings that offers innovative and sustainable solutions in buildings and their management: We build CO2-free (zero CO2) green houses at market price, with performances much higher than the average. We design buildings that build positive community, environments that care for people, giving answers to new ways of understanding the social relationships between what is private, common and public. We develop an ethical and transparent management, without speculating and always looking for triple balance of projects (social, environmental and economic). We work for an economic model that responds to the needs of today’s society, within what we understand as economy for the common good, collaborative economy and B corporations or SANNAS companies
