SouthWest Mercer Island
Tucked along the serene western shore of Mercer Island, 8001 West Mercer Way offers a rare and intimate connection to Lake Washington—just ten feet from the water’s edge. This five-bedroom, three-bathroom residence captures the full arc of sunlight, from the soft glow of sunrise to the last drop of blue fading into dusk. It’s a place where eagles soar overhead, deer wander through the trees, and the lake reflects every mood of the sky. Life here moves at a gentler rhythm, defined by privacy, quiet, and a deep appreciation for nature’s beauty. Residents enjoy the feel of a remote retreat while still being only twenty minutes from the vibrant urban centers of Seattle and Bellevue. This part of the island draws those who seek a chill, unhurried lifestyle without giving up convenience, and the community reflects that— laid-back, welcoming, and deeply connected to the landscape. With top-tier schools, a strong sense of safety, and access to trails, parks, and water sports, this home is more than a residence—it’s a front-row seat to the rhythm of the island.
Sounds and Sights of Nature
The perimeter of Mercer Island from the water and across the lake appears to be forested. Of course, there are homes and depending on various things will determine the size of the lot. This home is at the base of a sloped lot, a whisper from the water on a 15,640 sq foot lot. Because the lot is populated with native trees and plants, it is a welcome home to other friends who add to the sights and sounds along with the water views and sounds.
Eagles soar overhead, riding the breeze with quiet confidence, their shadows drifting across the water.A single or sometimes family of deer wander through the landscape, unhurried and graceful, as if they, too, are drawn to the calm. The soft rustle of leaves and the rhythm of birdsong create a natural soundtrack that shifts gently with the time of day.
Down by the water, waves lap softly against the dock, a steady, soothing rhythm. In the early morning and golden evening light, reflections dance across the lake’s surface, and the air carries a sense of stillness that invites you to pause, listen, and simply be.
Right of First Offer for 8025
100+115 feet of waterfront

This option presents an extraordinary opportunity to unlock value. Whether your dream is to build one expansive estate or thoughtfully design two or even three distinct homes, the flexibility here is unmatched. What would you do?
Currently, only 8001 West Mercer Way is offered for sale. This exceptional parcel features a deep-water dock and a grandfathered foundation just 10 feet from the shoreline—a build opportunity that could never be replicated under today’s zoning.
Next door, 8025—under the same ownership—offers a grandfathered swim dock, a historic log cabin, and a modernized outbuilding, with a primary home perched at the top enjoying sweeping lake and mountain views. While the owner intends to remain at 8025 for now, they do plan to sell in the future.
The exclusive legal right of first offer for 8025 is attached to the 8001 parcel offering the buyer of 8001 a unique opportunity to potentially acquire both parcels and establish one of the largest legacy waterfront estates on Mercer Island.
