The City of Sydney engaged McGregor Coxall to design the 6,400m2 Green Square Drying Green Park. This park serves to extend the landscape character of Zetland Avenue and form a place of respite against the contrast of the paved, formal, and multi-functional urban environments of the library and plaza. The Origami Green concept proposal folds the topography to form a variety of spatial experiences as well as maximising useable lawn areas, sun exposure and creating a sense of privacy and containment. Buffering of noise and winds from the surroundings is also improved. Within the park, a tilted lawn transitions to a large open lawn with sheltered BBQ and dining area. A tiered arrangement of wetlands treat and harvest storm water along Zetland Avenue and Portman Street. McGregor Coxall's concept design has recently been approved and is currently in the documentation phase. The Drying Green was completed in October 2022.
