This is the latest step in the hundred year evolution of an urban carriage house. Converted to a garage in the mid-20th century, the space was used as a painting studio before the current owner dismantled the slab and roof to make a private backyard in the busy Fells Point neighborhood of Baltimore.



In 2010, the owner commissioned Kroiz Architecture and the Working Group on Adaptive Systems to reconstruct the garage, and create a new backyard space on the roof.



This space is designed to take advantage of the runoff from the house to irrigate the green roof, container gardens, and vertical kitchen planting on the west wall. The rear portion of the green roof is dropped an extra 18", to allow the planting of more extensive berry bushes and small trees. This planted area provides passive cooling in the summer, reduces the urban heat island effect, and helps to keep rainwater from overloading Baltimore's antiquated storm drain system. The harbor is located only a few blocks from the house, native plantings can significantly reduce pollution that flows into the Chesapeake Bay.

A hardwood slatwall privacy fence is designed to screen out views from the sidewalk, and exposure to the parked cars below, while opening up to views of the skyline and waterfront beyond. Canvas sunshades, made from recycled sailcloth, further serve to tune exposure to heat, light, and air.

The privacy screen acts as a second shell around the back of the house, a container that extends the living areas outward to create and shelter a new green space in the city.



This project is being built by Flying Colors/ Conscientious Craftsmen, with green roof specifications by Conservation Technologies, construction is expected to be complete in August, 2011.
