About This Home

Experience waterfront luxury vacation-like living in this extensively remodeled exceptional home on the main shores of the quiet water portion of Oswego Lake. With five bedrooms, an office, a gym and four and a half bathrooms, this inviting home was mindfully designed around extensive entertaining and everyday ease. At every turn, there is a harmonious blend of upscale finishes and light bouncing off of water outside into serene spaces inside. The expansive walls of glass dissolve the boundary between indoors and out, opening to panoramic waterscapes in every direction and a rare large, flat yard. The gourmet kitchen centers around an impressive island with beautiful surfaces, custom cabinetry, highest end appliances and a generous butlers pantry designed to house all the necessary kitchen accoutrements. The main level also boasts a large bedroom with ensuite bathroom, the office, a stunning design forward powder bath, a bespoke bar and a cleverly customized wine cellar. Upstairs, the primary suite is a peaceful retreat with impressive scale and features that include lake views, automated blinds and absolute privacy. Its spa-inspired flow embodies relaxing extravagance with a freestanding tub, heated floors, a steam and rain shower, dual sinks with illuminated mirrors and a custom walk-in closet tailored for curated wardrobes. On this level, you'll also find two additional bedrooms, two full bathrooms, an expansive and inviting family room with another wet bar and a dedicated fitness area with breathtaking lake views. The third floor flexible space, currently a bedroom, showcases that this residence offers beautifully designed options for every need. Outside, a spacious deck cascades through custom low-maintenance, natural landscaping to your private 72 feet of waterfront. The boat house is equipped with a hydraulic lift sized for the maximum length boat allowed on the lake and there is an additional dock. Lake life has never been so beautiful or so easy!
