The register’s text, word for word
Description
The Lougheed Block is a pre-World War One, L-shaped, mixed-use commercial building immediately adjacent to the former Sherman Grand Theatre thus creating a rectangular block. It is a six-storey steel and concrete Chicago Style building clad with brick and sandstone. It occupies portions of nine lots in downtown Calgary and is located on the northerly edge of the historic commercial centre of the city. The designation applies only to the L-shaped building.
Heritage value
The heritage value of the Lougheed Block lies in its representation of Calgary’s tremendous commercial growth prior to World War One. The block served as a major centre of commercial activity for most of the twentieth century. It is a good example of the Chicago Style of commercial architecture, which embodied the sense of optimism in Calgary's economy. One of the few remaining examples of this style of architecture in Calgary, it is a familiar downtown landmark.
Heritage value also resides with its direct association with the original owner, Senator James A. Lougheed, a prominent lawyer, landowner, and member of Calgary’s business elite who was later knighted. The building has had such influential tenants as the United Farmers of Alberta (U.F.A.), United Grain Growers (U.G.G.), and Calgary Petroleum Products. There was also residential space on the top floors, commercial retail space at street level, as well as access through the building to the Sherman Grand Theatre.
