TL;DR Killarney/Glengarry is an inner-city southwest Calgary community laid out on a tight grid from 17 Avenue SW down to Richmond Road SW, between 37 Street SW and 25A Street SW. The housing is the story: post-war bungalows on 50-foot lots, older homes on 25-foot lots, and hundreds of newer side-by

TL;DR Acadia is a 1960s community in south-central Calgary (SE quadrant), running from Macleod Trail east to the Bow River, between Heritage Drive and Southland Drive. Seven in ten of its homes were built between 1961 and 1980: detached houses on the crescents, plus a large stock of low-rise condos

TL;DR Signal Hill is an established southwest Calgary community on a high ridge west of Sarcee Trail, between 17 Avenue and Glenmore Trail, with views west to the Rockies. It was built almost all at once: four in five homes went up between 1981 and 2000, so most houses here are now 25 to 45 years ol
