This accommodates a mysterious door to the right of the stoop. This former horse walk is a passageway leading to the garden and the 25' wide carriage house. According to the 1970 Chelsea Historic District Designation Report, "This is the only Greek Revival house in the Historic District which retains a passage to a rear building." The symmetry and simplicity of this 'rear building' cannot be overstated. It stands two floors tall and has five windows, two on each side and one above the center door. All of them overlook the garden. The 1st floor has a full bath and a kitchenette. A spiral staircase brings you up to an open 2nd floor which is currently being used as office space. Built in 1846, 331 West 20th Street is located on a tree-lined, townhouse block between 8th & 9th Avenues, in the vibrant Chelsea neighborhood.
