A bird tower was crafted with the intention of blurring the boundaries between humans and animals. The structure incorporated nests specifically designed for owls, ospreys, and sandpipers, seamlessly integrated into its overall form. Owls typically nest at around 50 feet, while ospreys prefer heights of 20-30 feet, and sandpipers typically nest in moist terrains. Each nest was tailored to account for factors such as ospreys’ preference for flat surfaces and owls’ inclination towards nesting in crevices. The design of the bird tower encompassed not only the framing system but also the circulation within the structure, with the purpose of accommodating observation, education, and exhibition spaces. As a second step in this project, the stairs were arranged to cascade, serving dual functions as both shelters and vantage points from which to admire the Empire State Building and the bird tower itself. While following the same circulation path as the watchtower, these stairs were designed with human comfort in mind along with panoramic views.
