Heritage Character Statement

A Modern style office building - it features large flat wall surfaces with expressed structural grid and defined modular glazing panels.

Summary History

Following a major oil discovery at Leduc, Alberta in 1947, Calgary quickly emerged as the administrative centre of western Canada's petroleum industry. Very little major construction had taken place in the city since before the Great Depression, and oil company representatives initially made their headquarters in hotel rooms and aging office buildings. The first major project to address the increased demand for office space was the Barron Building, designed by Cawston and Stevenson and completed in 1951. This

An inspection result is a record of one visit, not a verdict on the building. In the City's process a Not Acceptable result is an ordinary step: the inspector lists what must change and the work is re-inspected, which is why the most common outcome across the record is Acceptable Add Inspection. Most results relate to a single tenant improvement rather than the whole building. Inspector notes are The City of Calgary's own text at retrieval, with contact details removed; applicant and contractor names are never read.
