Spadina House is located right beside Casa Loma and is now a museum operated by the City of Toronto but was the home to several generations of the Austin family whose last survivor left it and its furnishings to the city and to the province in 1978. The original house was built in 1818 but it was enlarged and remodeled numerous times through the years from mid-Victorian to 1930's Colonial Revival with bits of Arts & Crafts, Art Nouveau, & Art Deco thrown into the mix. The museum was closed in 2009 and totally restored to the 1920s & 30s style before re-opening in 2010. The original property was 200 acres but even now it still sits on 8 acres of orchards, park, and formal gardens. I showed you a pic taken of Casa Loma as viewed from the other side of Spadina House grounds here.
