Year Built: 1911

Evaluated as a Community Historic Resource

The William M. Connacher Residence (1911) is one of Upper Mount Royal’s earliest homes, representing the area’s origins of as an elite residential suburb attracting Calgary’s newly affluent who were benefitting from the city’s pre-WWI economic boom. (Symbolic Value, Community-wide Significance)

This house contributes to Mount Royal’s assemblage of substantial, high-quality homes in a variety of styles. This is primarily a Craftsman house, but its exuberant false half-timbering also acknowledges the Tudor Revival style. (Style Value, Community-wide Significance)

Several early stone retaining walls survive in this hilly neighbourhood. The high sandstone block wall that runs across the front of this house and the one next door is a particularly large and impressive example. (Construction Value, Community-wide Significance)
