This simple, efficient design takes open concept to a new level. The first floor is centered around a substantial kitchen island, with room for dining and living areas on the left and right. The second floor master suite includes a large shower, two sinks, and a walk-in closet. Two additional bedrooms share a hall bath. Abundant windows provide plenty of passive lighting. The small footprint and energy efficient 2X8 construction are additional sustainable features.
