The line between where the inside of Chris and Nyla Marnay's cottage ends and the outside begins is blurred by large windows, sunlight, a cool breeze, and French doors opened wide. The couple's home was painstakingly designed so that the sun provides most of their light and heat, strategically placed overhangs and windows provide their cooling, and highly-insulating concrete walls keep temperatures stable.
Our Style: Passive solar, quarter circle, with mixed rough-face block and framing.
The inspiration for our home: Low maintenance, low energy, small, and cozy.
Favorite Element: The easy access to the outside, the light, and the view.
Biggest Challenge: No room to entertain or accommodate guests.
Friends Say About Our Home: It's an architectural marvel.
Biggest Embarrassment: Dog hair � and dirty windows (there are a lot of them to clean)!
Favorite Green Element: Passive space conditioning and our clothesline!
Proudest DIY: We worked with the architect to develop the design, and he later converted to green construction.
Biggest Indulgence: We accepted a very high cost-per-square-foot to achieve this kind of efficiency and an attractive design.
