The Black Barn is an agricultural and intern facility set into the rolling hills of New York’s Columbia County. Built ground up, this building houses livestock, a harvest processing center, and interns on this not for profit farm. While cohesively clad in black siding with a corrugated roof, the barn interiors respond to each of these programs through changes in material: heavy timber construction in the livestock wing, industrial finishes in the processing facility, and spare light filled interiors for the intern housing. L-shaped in plan, the exterior spaces become courtyards for animals and spaces for farm vehicles. By gathering these uses under one roof, the design of this barn focuses on the necessary efficiency of a working farm, without the clutter of multiple buildings within the otherwise unchanged historic landscape.
