Notman House is a gathering place for tech startups, entrepreneurs and founders situated in a historic building at 51 Sherbrooke Street West in Montreal, Quebec, near the Golden Square Mile. Completed in 1845 for Sir William Collis Meredith, the house takes its name from the celebrated photographer, William Notman, who lived there with his family from 1876 until his death in 1891. The house is the only surviving residence of its era on Sherbrooke Street, and one of Quebec's few residential examples of Greek Revival architecture. It was classified as an historical monument and added to the Répertoire du patrimoine culturel du Québec on December 8, 1979.
