Once an office tower, The Cornerstone has been reworked into rental apartments in Calgary's downtown west end, and that history still shapes the building — tall 8'6" ceilings, oversized triple-pane windows, and a floor plan logic that feels more spacious than typical new-build stock. Suites come as two-bedroom, one-bath layouts at 653 square feet from $2,300, and three-bedroom, one-bath homes ranging from 950 square feet at $2,400 to $2,500. Every unit includes quartz counters, stainless steel appliances, in-suite laundry, LED lighting, tenant-controlled heat and air conditioning, and a private balcony, with water and heat rolled into rent. The building leans into wellness and lifestyle extras rarely bundled together elsewhere: an SKA Thermal Spa, a dedicated esthetician work space, a fitness centre, and a tenant lounge for downtime outside your suite. Pet owners get a dog run and dog wash on-site, while commuters and cyclists benefit from indoor bike racks, an EV charging station, and access to the +15 Network for weather-protected walking through downtown. Security is a priority here, with 24-hour staffing, FOB entry, and three elevators keeping traffic moving smoothly. On-site maintenance rounds out the practical side. Pet friendly and leased on flexible terms, The Cornerstone suits renters who want a converted downtown building with genuine character rather than another cookie-cutter tower.
