This house boat is located at 3138 Cambridge Avenue, Milwaukee, WI . It was built by Edmund E. Gustorf in 1922. The house, a 550-square-foot, two-story residence shaped like a boat, has been a Milwaukee site to see for a long time. As it is known today, the “Boat House,” together with its 30-foot lighthouse, is a famous term for one of the most peculiar houses in the country and a City of Milwaukee Landmark. Practically every traveler who has past it has stopped to take a picture of what may be one of the city’s most photographed homes. It is now a Airbnb property.
