Seriya108. Secret Room Under Staircase. Sky Garden House. I think one of the reasons that many are skeptical about environmental design is because they think its terribly complex and costly.
It does take a bit more effort on the front end, but it's definitely not rocket science. This architecture by Guz Architects is a wonderfully developed minimalistic design with a curvilinear flare that really brings out the organic coverings. I'm most impressed with how design facilitates the needs of the plants and shrubs located throughout the house. See more at Guz Architects.
