This property is a piece of Canadian history on approximately 1.4 acres in the heart of St. Thomas' sought-after Courthouse District. Known locally as the "Snow White House," this mid-1800s residence offers the kind of scale, craftsmanship and setting that simply cannot be recreated. The home's history is part of its appeal. Local stories have long held that Sir John A. Macdonald stayed here during his tenure as Canada's first Prime Minister, following Confederation in 1867, adding another layer of intrigue to a property already well known within the community. The large foyer opens to generous principal rooms with soaring ceilings, detailed original crown moulding and hardwood floors. Formal living and dining spaces recall a different era of entertaining. Backing onto a magnificent wooded ravine, where Mill Creek winds through the trees and walking trails invite you to explore. The property feels remarkably private, with deer known to wander right up toward the home and its sweeping covered side verandah. Four bedrooms and four bathrooms offer substantial space to reimagine the home for its next chapter. Three grand original fireplaces create striking focal points throughout the home. This is a rare opportunity to own a historic residence on an exceptional parcel of land within the city. A detached two-car garage adds everyday practicality, while the circular drive offers generous parking and an easy flow for hosting gatherings, parties and evening soirées. For someone who sees the value in original architecture, history and land, the opportunity to restore and rediscover this hidden gem is truly one of a kind. The Snow White House is ready for you to bring its next chapter to life.
4 bedrooms, 3 bathrooms, about 3,500 sq ft, works out to roughly $163 per square foot. Chat with Zara if you'd like a deeper read on whether this detached fits your budget and timing.
