Who says historical opulence and modern luxury are mutually exclusive? The home at 166 High Park Ave. in Toronto proves you really can have the best of both worlds. It doesn’t just look antique, it’s the real deal — having been built in 1891 and owned by Herman Heintzman, of Heintzman piano-family fame. In 1986, it was designated by the Ontario Heritage Foundation as having architectural value and historical interest, and today, it’s up for sale. A gym, theatre, and game room make up the lowest level, all but guaranteeing you’ll be the life of the party.
