The SS Roth sits ready at dock, the bright red houseboat on the wet side of Lake Union's east shore. They're asking $925,000 for the 3 bedroom, 2.5 bath floating home. With 1,350 square feet and two stories, the foot print is small, but stand no top and get a much better view of downtown as a result. The outside is painted a shade of barnyard red with white trim, and that color scheme is carried inside, at least in the living room. From there, the paint is bright pastels carried throughout the rooms. The features that make it distinctive are outside. The white trim highlights a few peaked roofs over windows and doors that keep the house from being a box on floating blocks. That seemingly small change makes the house stand out. The flower boxes help, too. Even in houses worth almost a million dollars, the little things can matter most.
