This modern passive solar house in Nikaia, Greece, has an amazing view of Mount Olympus. Most of the materials used were either recycled or repurposed. Other green features include a steel frame wrapped in "prefabricated organic blocks" that acts as insulation, rooftop photovoltaic solar panels, and LEDS for low-energy illumination.
Designed by Christina Zerva Architects.
