Part of NAK’s work in the revitalization of Regent Park was One Cole, a mixed-use tower community consisting of over 250 residential units along with a full-size grocery store and other retail.

At the centre of the development is the Sky Park, a 0.5 acre urban park on the roof of the ground-floor commercial building. The park is an important new open space for the neighbourhood featuring an open lawn for play, accessible pathways, contemplative garden areas, a community patio with cooking facilities, and a terrace with community garden beds overlooking the park.

The park’s design uses intensive green roof technology to support 40 full-size shade trees and a wide variety of shrub and perennial plantings. Xeriscape principles and an extensive bio-filtration system were used to maximize available rainwater for irrigation.
