Set on one of Deer Island's largest waterfront parcels, this 1920s lake house offers approximately 3,500 square feet of living space across five bedrooms. The property features mature landscaping with specimen trees, a boathouse with drive-in docking and changing rooms, a private boat launch, stone lakefront walls, and a built-in outdoor grill area. Unlike many homes of its era, the interior layout is open and bright, with hardwood floors and generously sized rooms throughout. A window-lined living room with a wood-burning river stone fireplace anchors the main level, offering expansive lake views. The adjacent kitchen includes a butler's pantry and ample storage, flowing into a formal dining room framed by two walls of windows, and French doors that open to a sun-filled family room with stone accent wall. Upstairs, the primary suite features a jacuzzi tub, double vanity, and stall shower. Four additional bedrooms share a full bath and powder room. The lower level, with full-height ceilings, includes a large, windowed kitchen and a half bath, offering potential for expanded living or entertaining space. The setting ensures privacy and a quiet connection to the lake. A detached garage provides car parking and additional storage. Included in the sale is a separate, buildable lot at 90 Island Trail-offering space for future development or the option to maintain the surrounding privacy.
