The Ectoparasite seeks to exploit underutilized urban infrastructure—in this case, by latching onto a billboard adjacent to NYC’s High Line. Dependent on the billboard for suspension, the steel structure acts as a skeletal framework for enclosure (triangular glass and Cor-Ten panels), while wrapping in to support furnishings. Visually connected while physically detached from the park, the shelter provides an ideal lens for observers of city life and public space.
