Location: Mt. Washington Valley, New HampshireSize: 1800 square feetYears lived in: 24 — owned I know this tour is a bit of a departure from standard Apartment Therapy fare. It’s roomier, lake-ier, and more traditionally decorated than the average tour. But it happens to be my favorite house in the world and a place of peace. So I finally decided it was time to share it. This lake house belongs to my parents. They bought it twenty four years ago.
