Even in one of the coldest, inhabited climates on Earth, Iceland, green roofs are part of the landscape.
Inhabitat.com reports as one of its top 10 green stories of 2009, the Hof House. It was built from salvaged materials from an existing structure.
Other neat and green features, beside the gorgeous green roof include its passive solar design, geothermal heating, and very thick concrete walls.
