Background: Gigaplex Architects created this unusual and award-winning weekend home in 2006. Why Its Unique: This house was created by joining together two corrugated grain silos, the largest of which has a diameter of 27 feet. This is an approach that is akin to sustainability, Koliopoulos says. This silo home is a lot of fun and is a neat way to look at an existing product in a creative way. With a modest size of 1800 square feet, the designers saved space by placing the beds in cubbyholes that are cut into walls, each equipped with their own mini-entertainment systems.
