Lougheed Building

Construction year: 1911
Architect: McIlroy, D.S.
Builder: Unknown
Style: Commercial
Typology: Shop, Office and Apartment
Development era: 1906 to 1913 (Pre WWI Boom, Age of Optimism)
Designation: Inventory listing only

Senator James Lougheed, a prominent Calgary lawyer, businessman and politician, purchased thirty lots in downtown Calgary from the C.P.R. in 1884, and saw his land become the central core area of the city. He remained active in development, and in 1911 he built this six-storey brick structure at the corner of 1 Street and 6 Avenue SW.

The architect was D.S. McIlroy, also the designer of the First Baptist Church. A large portion of the building was occupied by the Grand Theatre Opera House (for a time known as the Sherman Grant Theatre). The Grand Theatre was used for worship by both Central United Church and Knox United Church while they were rebuilding. Besides the theatre, there were originally stores on the ground floor, commercial sample rooms on the next two storeys, and two and three-room living suites on the top floors.

The theatre remains today, although it has been divided into

Character-defining elements: Key elements of the Lougheed Block such as: - L-shaped form and massing - brick and sandstone cladding - prominent corner location - glazed light wells between the Lougheed Block and former Sherman Grand Theatre Key elements of the exterior such as: - Chicago Style with the elevation divided into three distinct zones - ground level large display windows; recessed store entrances; pilaster patterns defining ground floor storefront bays - theatre entrance on the west elevation and theatre exit on the north elevation - intermediate floors with grid-like fenestration pattern consisting of paired w
