Professionals or Investors, this grand beauty has been very well maintained and it represents a time of design and construction not seen in generations. There are currently 4 units plus an unoccupied professional dental office which has an entrance on Harbord Street with great exposure and is approximately 1,400 sq. ft. . Located in the heart of the Annex, you are right along Harbord Street at Markham and only steps to Bathurst, Bloor street nd the subway. This is a perfect live/work space or investment opportunity. Over 4,200 square feet, the building was extensively renovated in 1990 and the roof was fully replaced 2 years ago. There is parking at the rear with easy access off Harbord St. This bustling neighbourhood attracts people who want a beautiful downtown area with character, architecturally beautiful homes from the early 1900's and super convenient access to downtown, U of T and hospital row. Currently there are 2-two bedroom units, 1-one bedroom unit and a bachelor unit. Three of the units have their own balconies. The basement is a high and very dry basement with a seperate entrance, storage and a laundry area for the dental clinic. Plans currently exist to convert the dental office into 2 more residential units.
