Who would have guessed that an entirely recyclable, zero-emissions, zero-carbon, sustainable house could be such a style icon? Rising four storeys in Stuttgart, Germany, this modern glass edifice has nothing to hide. The home’s front facade features photovoltaic panels that power the house and light it up when the sun goes down. Adding to its amazing sustainable features, the house also boasts geothermal energy and cooling. Minimal style is king at House R 128, which has no interior walls, and a few modern pieces that characterize the home’s open-concept living areas. via trendir
