216 ACRES ! Spectacular country farm available for sale for the first time in nearly 80 years. This farm is located within the fastest growing community in CANADA and is situated within minutes of the new Southlake Hospital ( being built) and a new proposed 1700 home+ development in Queensville. There are few acreage parcels of this size and quality in the GTA. The TWO Houses on the property allow the accommodation of 3 families. The main house is a large century farmhouse circa 1890 with a Napier Simpson addition, two family home with separate entrances and living space. One half has 4 bedrooms, while the other has three. This original portion of the home was built approx 1890 or earlier with 13 inch baseboards and 10 foot ceilings on the main floor. It is an elegant and stately home. There is also a detached bungalow accessible from Mill Rd. This property may have the possibility to obtain a fill permit from regional and local municipalities, for a 5 cubic acre previously quarried pit if certain conditions are satisfied at the time of application. Rarely does a farm of this size and quality become available with such a premium location. (Bank barn in photos has been removed)
