About This Home

As of May 2014

Grand Mercer Island 1.7 acre waterfront estate. The sylvan road meanders through the vast grounds, opening to the light-filled, gracious, and tastefully crafted 3800sf home, capturing lake views from nearly every room. Breathtaking expanse -the front lawn alone is larger than many waterfront properties. One of few street to water estates, with 85' of level lakefront, mountain and sweeping lake views. Large dock with covered and side tie moorage. Magnificent scale, a breathtaking experience.
