This site is significant because...

Nelco Square, constructed in 1979 is highly valued as a superb example of a late Brutalist-style office building in Calgary (Style Value, City Wide Significance).

Nelco Square also has significant symbolic value for its association with Calgary¿s thriving economy in the late 1970s as a result of soaring oil prices and increased development of oil and gas interests in the province, and as a marker of the shift to constructing office buildings outside of the downtown core in newly established industrial areas (Symbolic Value, City Wide Significance).

Character-defining elements: Character-defining elements of Nelco Square include, but are not limited to its: - form, scale, and massing as expressed by its: three-storey height; square plan; flat roof; two massings with upper volume overhanging lower volume and supported by narrow pilasters that become longer as grade slopes down towards the east; corner pilasters at 90 degree angles; main entry on 5 AV; - steel-frame construction with: concrete foundation; pre-cast decorative concrete panels and window fins in sandstone colour; formed concrete with exposed aggregate for pilasters and base of building in sandstone colour
