About 333 Keystone Avenue

Welcome to one of Whidbey Island's most compelling waterfront opportunities. Perfectly positioned on the shores of Admiralty Bay, this rare south-facing beach house offers the luxury of year-round sunshine, spectacular sunsets, and walk-out waterfront living that is increasingly difficult to find. Spanning approx. 2,380 square feet, the home offers exceptional space rarely seen in beachfront properties. With three official bedrooms, a generous loft with its own en suite bathroom serving as a fourth sleeping area, and abundant storage throughout, there's ample room for gatherings, visiting guests, remote work, or extended stays. Expansive windows capture sweeping views of the bay, shipping lanes, mountains and ferries, transforming the water and sky into ever-changing works of art. The open, light-filled living spaces invite effortless entertaining and relaxed coastal living, while the seamless connection to the outdoors encourages a lifestyle centered around the beach. Step directly from your home onto the shoreline—no bulkhead, no barriers, just natural waterfront access to beachcombing, kayaking, paddleboarding, fishing, and endless exploration along the shore. Whether you're seeking a luxury second home, a waterfront retreat, or a legacy property to enjoy for generations, this residence delivers the quintessential Whidbey Island lifestyle. This is more than a beach house—it's a sanctuary where luxury, tranquility, and the best of island living come together.
