Greystone Barn in Westtown Township was a working animal barn prior to its conversion into a home in the 1970s. Before its purchase by the current residents, no work was done to the structure in more than four decades. The new owners, relocating from an urban townhouse, wished to create a vibrant and livable space while still honoring the traditional form and design of the early 19th century stone barn. Originally four isolated floors, the barn was transformed by a design approach that opened the space from floor to floor to create a new vertical dynamic. The addition of a second stair between the ground and second floors creates overlooks through the structure that allow the spatial aspects of the barn form to be experienced from unique vantage points. For the interiors, materials intrinsic to a barn are mixed with whimsical touches – like a powder room featuring Hunt Slonem’s bunny art wallpaper and a master bedroom closet housed in the original round feed silo – to create fun yet functional spaces. An abundance of wood- and stone-faced wall space allows the owners to display their art collection in an almost gallery-like fashion. In certain areas, the preserved stone walls of the barn are left exposed to serve as art in their own way. Staying true to the original spirit of the barn, aged timbers were replaced in kind, new openings were framed with reclaimed timber, and old flooring was replaced with river-recovered heart pine. A system of wood and wire railings maintain transparency and allow views within the upper stories. To bring the structure into the 21st century, all systems were updated and the residence was reinsulated to significantly tighten up the building envelope; both vastly improving energy efficiency. The excitement of “living in a barn” was made into a reality for this family as it has become their home.
