Toronto’s iconic CN Tower has reopened its observation deck to the public following an overhaul by locally based architecture firm Superkül. Nearly 1,200 feet in the air, a medley of natural elements characteristic of the Canadian landscape defines the reimagined interiors. “While the organic forms and materials create a sense of serenity and security, the new glazing—the more steeply angled glass enclosure as well as the revitalized glass floor—offer a more exciting and dynamic visitor experience, especially for the thrill seekers among us,” says Superkül principal Will Elsworthy. “We wanted people to feel like they were perched in a treetop looking out over the city and the lake.”

Inspired by the boreal canopy, modular oak-laminated fins extend centripetally from undulating biophilic ceilings to draw gazes toward the Ontario sprawl. Original vertical glazing and glass floors are replaced with new sloped structural glass to establish “Tilt Zones” that further intensify views now fully unobstructed following the removal of the outdoor terrace’s steel cages. A new four-story maintenance gantry is attached to the uppermost level of the facade, while new perimeter enclosure systems and corresponding glass panes are installed against new fiberglass concrete benches. Additional upgrades include a 40-foot–long floor-to-ceiling video wall, a pair of panoramic screens, and three large-format video displays.
