Model of an eco home by Bengt Warne, displayed at the Stockholm museum for architecture. The house actually looks like a greenhouse. It is said to be selfsufficient as a mini eco system is created by the glass surrounding the home. Waterdrainage and heat, but also planting and eating self grown vegetables seems easy in this place.
The real house is located at Saltsjöbaden, Sweden, and built in 1976 -1980.
