The Imperial Lofts is the rebirth of the old Imperial Optical Warehouse and Office Building. The complex consists of two historic buildings – a 6-storey authentic post-and-beam loft building designed by Stephen Burwell Coon (S.B.Coon) in 1910 as a warehouse for coffee and spice merchants The J.M.Lowes Co., and an adjacent 3-storey late Art Deco factory and office building designed by Benjamin Brown in 1945 for the Surgical Supply Co., later Imperial Surgical. Both buildings were occupied by Imperial Optical from the 1970s thru 1990s, and have been restored to a 65 unit modern condominium complex. The 6-storey building at 90 Sherbourne boasts exposed original wood beams and posts, wood floors, exposed brick walls, exposed ducts and pipes, and 10 1/2 foot ceilings. The 3-storey building at 80 Sherbourne boasts 10 1/2 foot ceilings, exposed ducts and pipes, and in some suites original wood beam ceilings and wood or terrazzo floors. Both buildings are listed as Contributing Properties in the St. Lawrence Heritage Conservation District.
