When you can park your kayak beside your front door you definitely save a lot of time and worry. There's no need to spend time pulling the kayak out of storage, lashing it to the roof of the car, hoping it doesn't fall off as you drive to the launch site, and then reversing the process. Instead, step onto your front porch, into your kayak, and go cruise around with the ducks, geese, and maybe a few otters. Living on a houseboat certainly has its advantages.
This "Hip [James] Jessup NW contemporary" has 2 bedrooms and 1.5 baths, and is moored on the east side of Lake Union. It is nestled in a community of other houseboats, so the view is mostly of other innovative architecture. That may be one reason they let in more sunshine with skylights, open the space with vaulted ceilings, and kept the decorations light. They're asking $985,000 (plus $475/month) for a house on concrete floats that has been around since 1974. Updates happen, and it looks much newer than the Nixon era. It is hard to know how big it is because there is no square footage listed; but there's enough room for full kitchen, dining area, living room, den/library, and a master bath large enough for two. When you've been inside more than enough, and getting out on the lake isn't appealing, there's always the rooftop deck that gives you one of the best views of downtown Seattle. Have fun watching the float planes land.
