Despite the cottage’s many renovations, the den— with its fireplace and wood-paneled ceiling and walls —is original. The cherry floors are new, however, as are the furnishings. The sofa and chairs were transferred from an apartment the homeowners have in Boston. The table of interlocking squares is from Roche Bobois. Among the things that sit on top of it: a vase from a local craftsperson and ostrich eggs procured in Cape Town.
