The Bayliss Boathouse // Positioned on the southern shores of Lake Washington, The Bayliss Boathouse represents one of the Pacific Northwest’s rarest ownership opportunities—an architect-designed freshwater moorage facility crafted to accommodate vessels up to 60'. Designed by Bayliss Architects, the structure transcends the utilitarian nature of traditional marina infrastructure, blending refined architectural detailing with serious functional capability. Freshwater moorage significantly reduces corrosion, wear, and long-term maintenance relative to saltwater environments, offering an ideal solution for discerning boaters focused on preservation, security, and convenience for a prized vessel. Framed and wired for future loft expansion, the structure also provides the opportunity to create additional storage or operational space tailored to ownership needs. Ideal for a Lake Washington–centric boating lifestyle, the property is particularly well suited to owners of 45'–60' cruising or performance vessels seeking protected moorage within a private ownership setting. Opportunities of this caliber and scale rarely become available, especially with fee-simple ownership rather than leased marina arrangements. A singular offering combining architectural pedigree, scarcity, and long-term vessel preservation in one of the region’s most tightly held boating environments.
