SAMVS open modular houses make a great solution for low income housing programs
 given their fast construction time, simple materials, modularity and   
overall efficiency. Comprised of modules that serve specific functions  
 and are fabricated in a local factory, the home can be built in just 
one   and half months for 700 Euros per square meter.
Industrial in design, the home nevertheless boasts sensible materials
   that ensure sufficient thermal massing and ventilation. The interior 
 is  light and fresh and the green roof
 helps with insulation and enhanced air quality. Rainwater is harvested 
  and recycled and the entire home is powered by both solar thermal  
plates  and photovoltaic panels.
   It’s hard to go wrong with the SAMVS units: they save materials,   
energy, time and money, and they’re not so hard on the eye either.
