After successful transformation of overhead infrastructures into leisure spaces, such as the New York HighLine park, new possibilities are being explored underground. The LowLine project uses crowd funding to turn the old Williamsburg Trolley Terminal, an underground complex, into a community park. The complex was built in 1903 and has remained unused since 1948.
The location in the Lower East Side, which lacks public green space and business opportunities, challenged a neighboring architecture firm to come up with this plan. The designers developed a system that captures sunlight and transmits it to the subterranean park, in sufficient quantities for photosynthesis, in other words to grow trees and other plants.
