735-737 Richmond Street was listed on the City of Toronto Heritage Register on 18 July 2019.

James Lukin Robinson built 32 Garrison Common Cottages ( also known as Robinson Cottages & misidentified in city records for some time as Robertson Cottages). 16 cottages were first built on Mitchell Avenue, then 8 or Richmond Street West and 8 on Adelaide St. West. These brick, semi-detached cottages were built as a group, 4 pairs on one street backing onto 4 pairs behind. The houses were occupied by industrial workers, industry linked to the railway lines that passed through the neighborhood. All the Garrison Common Cottages on Adelaide St. are gone, but 7 cottages remain on Richmond Street W, and 4 cottages are left on Mitchell Ave. These are now among the oldest modestly scaled residential houses in Toronto. Robinson intended to build a similar group of cottages near the train station in Mimico, but the project collapsed before any were built. Now: 4 of the cottages on Richmond St. W. are listed. A Demolition Permit has been applied for 2 of the cottages on Mitchell Ave. and 2 more are for sale and being advertised as potential for demolition & rebuild.
