As an architectural form, culverts create a space that lies on the border between outside and inside. Frequently used to redirect waterways under roads and railways, culverts often function as the connecting link between two natural environments, moving under or through manmade environments. If bridges are a passage for human transportation over a natural obstacle, conversely, culverts facilitate the passing of the natural world through the man-made. This project explores the solitude and strangeness of these spaces.
