Much like the Farnsworth House by Mies van der Rohe.
Very open, flowing and dynamic living spaces carved cleverly by the use of materials and the circulation of spaces. Pretty neh... Imagine relaxing in the living room whole day not doing anything. No loud TVs. (A cool laptop and internet connection is sufficient. Ok, maybe a flat panel TV just for console gaming. =p)
"...the design integrates concrete flooring to absorb the sun’s warmth in the winter, operable windows and large sliding doors to facilitate natural ventilation and low-maintenance recycled materials."- freshome.com
