My wife and I are on vacation and have spent the day in Seattle, Washington. We took the Duck Tour which is both educational and entertaining and I would highly recommend it if you are spending any time in downtown Seattle.
One of the perks of the Duck Tour is that you get to go out onto Lake Union and see the floating homes (view some interior photos at this link). Originally the cheapest place to live in town, no longer. It is now the most expensive place to live. Most of the floating homes cost over a million dollars. The exception is the barge homes that start around $150k and go up to around $800k if you can get one. Though out of most of our price ranges I think the designs are inspiring and I hope you enjoy the following photos. Unfortunately no interior photos as we were not allowed into the homes.
