Found this on enpundit magazine but this little tiny house has been featured in quite a few places!
Designed by Jessica Helgerson, Tiny House sits on a five-acre property on Sauvie Island, an agricultural island on the Columbia River 15 minutes north of Portland. Being only 540 square feet, the home is an excellent example of efficient use of space. via shoeboxdwelling
“The house is an interesting experiment in reduction and reuse not only because it is only 540 square feet or because it was remodeled using nearly exclusively reclaimed materials, but because the building itself is now being recycled for the fourth time. It was first built in the early 1940s as part of Vanport Village; a quickly erected development built to house shipyard workers. When Vanport Village flooded in 1948 this particular little house was floated down the river to Sauvie Island, where it became the goose-check station. Years later it was remodeled to become a rental house.”
