A magnificent 1923 Colonial Revival residence, beautifully landscaped and equally extraordinary within. Ascend the wide steps past layered plantings of shrubs, trees, and flowers. Inside, the home opens to grand, light-filled spaces reminiscent of another era, anchored by a generous living room with a Batchelder tile fireplace. Original hardwood floors, stepped ceilings with crown molding, and classic multi-pane windows infuse the home with natural light and views of the lush garden. The kitchen delights with bold cobalt tile, a large center island, gas cooktop, Sub-Zero refrigerator, and a built-in desk nook, all opening to a sunny eat-in area with French doors directly onto the back deck and garden. The formal dining room is proper and elegant for big affairs or intimate dinners. Upstairs, four generous bedrooms await. Discover a serene primary suite with treetop and lake views, a petite library nook wrapped in custom built-ins, and a bedroom-turned-private-office with floor-to-ceiling shelving and a lake view. The lower level is a real revelation with high ceilings, recessed lighting, a warm hangout room, a comfortable en suite bedroom for guests. A legit private theater with leather recliners, cinematic sound, and dedicated climate control. Outside, find the expansive flagstone patio, wood-fired pizza oven, fully equipped outdoor kitchen, a stone wall fountain draped in climbing vines, and an alley-access two-car garage with plenty of storage.
