George Stephen House

George Stephen House (also known as the Mount Stephen Club building) is a historic mansion located in the Golden Square Mile in Montreal, Quebec, Canada.

From 1883 to 1896, the house was the residence of George Stephen, 1st Baron Mount Stephen, and then, from 1896 to 1925, of his brother-in-law and his successors . From 1927 to 2011, the building housed the Mount Stephen Club, a gentlemen's club that brought together Montreal's and international elite. In 2012, a luxury hotel project, called Le Mount Stephen, began to take shape, planned to occupy part of the residence. The project required the construction of a contemporary annexe at the rear, with 90 rooms, shops, and an indoor parking garage with 96 spaces. The hotel's opening, originally scheduled for June 2015, was postponed to May 1, 2017.

Built between 1881 and 1883, the residence was designed by architect William Tutin Thomas in a combination of architectural styles characteristic of Victorian architecture. It blends elements of the Italian Renaissance, Italian Baroque, and 17th-century English Baroque. The Italian Renaissance style, however, is the dominant style of the front façade. The interior, also designed by the same architect, was primarily decorated by the team of carpenter and joiner Archibald McIntyre, stained-glass artist John C. Spence, and the cabinet-making and interior design firm Jacques & Hay of Toronto. Cabinet-maker James Thomson also produced some bespoke furniture for the residence.

The building is subject to certain protection measures. On October 14, 1971, it was declared a National Historic Site of Canada by the Historic Sites and Monuments Board of Canada. It was also designated a heritage building by the Quebec Ministry of Culture and Communications on March 11, 1975. On December 10, 2004, the building was designated a immeuble de valeur patrimoniale exceptionnelle (building of exceptional heritage value) by the City of Montreal. The building was declared to be located within the aire de protection de l’édifice du club Mount Stephent (Mount Stephen Club building protection zone) on April 11, 1978, and within the secteur de valeur patrimoniale exceptionnelle Guy-Drummond (Guy-Drummond sector of exceptional heritage value) on December 10, 2004.
