10. The Riverwood Chalet is one of seven a-frames built along the Middle Fork of the New River in Blowing Rock, NC in the 1970’s. These homes were constructed as a vacation rental community, the Roaring River Chalets. In 2011, the houses were renovated and converted to a planned urban development. At just under 700 square feet, this unique a-frame boasts two balconies over the the river, a loft and a stone fireplace.
