Sharing New Details About the OAA Landscape Design Competition

Earlier this month, the OAA announced it would soon launch an anonymous, juried Landscape Design Competition for the ground of its Toronto Headquarters. (You can read the initial press release here.) The OAA Building Committee and Association staff continue to work with its Professional Advisor, architect Joe Lobko, on details for the competition, which is on track for its official launch on Wednesday, March 20.

This article looks at how eligible teams can register for the opportunity, as well as provides more information on the program’s goals, jurying, and general timelines.
