The double cottage at 726-728 Toulouse Street, including a garçonnière at the rear of the lot, was purchased by The Collection 1990. During the summer of 1991, an archaeological dig revealed evidence of all the structures that existed prior to the house now on the site.

Archaeologists found indications of the first structure, the French barracks from the 1720s; a structure burned in the fire of 1788; a residence from the period 1790 to 1820; and debris related to the existing cottage that was built around 1830. The philanthropist Thomy Lafon, who owned extensive real estate in the city, bought the cottage in 1876 and left it, upon his death, to the Society of the Holy Family.

Constructed of brick-between-posts, the small structure—like a final mark of punctuation—is positioned at the far end of The Collection’s property on Toulouse Street. It houses the workspace of the exhibition preparation department.
