This project will vitally serve as a large-scale Lepidoptera terrarium. A

permeable vertical meadow, the Monarch Sanctuary is a double-skin
facade integrated with an open garden that serves as a crucial way station and habitat for the at-risk butterfly. It will bolster the Monarch’s presence in the city through two strategies: open plantings of milkweed and nectar flowers on the roof, rear facade, and terrace will provide breeding ground and stopover habitat for wild monarchs, while semi-enclosed colonies in the atrium and street side double-skin facade will foster monarch population growth. The insects will have fluid open access to join the wild population, enhancing overall species population numbers.
