Minimum Viable Homes: Minimal, efficient, ecological homes

Minimum Viable Homes

Minimal, efficient, ecological homes

The NGO Light Humanity is developing minimal homes that are self-sufficient, efficient and ecological

Minimum Viable Homes is the project of Light Humanity's Ecosocial Innovation Lab to make a minimal home efficient, ecological and self-sufficient all at once. It has been led since 2025 by the organisation's founder, Eugenio García-Calderón Huerta.

  • What it is: a project to develop minimal, efficient, ecological homes.
  • The goal: for those homes to be self-sufficient.
  • The project's image: the cover shows a small living unit mounted on a trailer, thrown wide open.
  • Where it stands: in development; no dimensions, materials or costs have been published yet.
  • Where it fits: in the lab's Housing area, alongside Organic Urban Design, the Ecological Homes Factory and three communities.

The minimal dwelling, a concept architects were already debating in 1929

The project's name draws on a term with a history in modern architecture: the minimal dwelling.

  • 1928, La Sarraz (Switzerland): a group of 28 European architects, including Le Corbusier and the Spaniards Fernando García Mercadal and Juan de Zavala, founds the International Congress of Modern Architecture (CIAM).
  • 1929, Frankfurt am Main: the second CIAM focused on the minimal dwelling, the “Existenzminimum”, and on Ernst May's housing work.

Minimum Viable Homes shares its area with five other lab projects. It also has the idea of self-sufficiency in common with Organic Urban Design.

From community design to ecological homes
