An oasis in the heart of Thornbury, one of Southern Georgian Bay's most beloved waterfront towns. Tucked at the end of a quiet dead-end street, this blue-and-white two-storey rests on a beautifully treed hillside with direct frontage on the tranquil Mill Pond, where the Beaver River widens on its way to Georgian Bay. Watch swans glide past from your own dock, launch a paddleboard from your shoreline, and enjoy the calm of a no-motor pond minutes from town. Nearly 2,000 sq ft above grade offers principal rooms joined by a double-sided brick fireplace, a kitchen with white cabinetry, gas cooktop, double wall ovens and butcher-block island, and five main-floor walkouts to the deck and gardens. Upstairs, the water-facing principal bedroom has a vaulted ceiling, hardwood, room for a sitting area and its own fireplace, beside a spa-style hall bath with glass shower, jetted tub, double vanity and concealed laundry; a second bedroom enjoys a private 3-piece ensuite. The walkout lower level adds a terracotta-tiled family room with brick fireplace, covered patio and 3-piece bath. Outside is where this property truly shines: a heated in-ground pool and cabana, multi-level decking, limestone terraces, firepit and mature gardens, then recapped stairs descending through a private wooded valley to a gazebo and dock at the water's edge. A separate two-bay garage complex adds a finished lounge/flex bay, kitchenette, 3-piece pool bath and bright loft with skylights - guest overflow, gym, studio or games room. Interlocking drive parks six. Municipal water and sewer, natural gas, central air, 200-amp service and generator connection. Stroll to Thornbury's restaurants, bakeries, boutiques and the harbour; ski the private clubs and Blue Mountain in winter; spend summers on Georgian Bay's beaches, golf courses and the Georgian Trail. Vacant with flexible possession - a rare chance to own a true in-town waterfront sanctuary where small-town charm meets four-season adventure.
