About This Home

Designed by architect Gerald Van Slyck in the late 1950s to early 1960s, this distinctive floating home captures the essence of midcentury design with a NW sensibility. Vaulted ceilings, clerestory windows, and generous skylights welcome shifting sunlight that dances through the rooms & reflects off the water, giving the space a luminous, ever-changing quality. Outdoor areas frame tranquil Portage Bay views, while the intimate four-home co-op dock offers a genuine sense of community. Includes one dedicated parking space & a 43-foot moorage slip - a timeless blend of architecture, light, & waterfront serenity. Second from the end, this is your perfect retreat from the daily city life putting you absolutely in touch w/ nature at it's best.
