Sous Bois..Sous Bois has four-foot-thick, dry-stack limestone walls. Three rooms on the first floor date to the 15th century. The second story, which Luce turned into a master bedroom suite, was added 300 years later. He describes the original interior wall plaster as "brut, unrefined and honest." Over time, hearth fires in the house's single fireplace blackened the ceiling beams and darkened the living room.
