Site size: 3,810 square feet Project size: 3,200 square feet Program: A dilapidated 18-century barn renovated for a modern residence. Location: A rural site in South Yorkshire, in northern England. Solution: The architects inserted a second floor into the two-story-high stone barn, yet managed to keep the original sense of the open plan. Two bedrooms on the upper floor are connected by a walkway with a glass balustrade that overlooks the living and dining areas. Construction and materials: The architects inserted a steel frame to support deteriorating walls, with a ring beam running around the perimeter of the kitchen area.
