Preparing to renovate their new Back Bay condo, Bill and Lisa Vanderweil were sure about one thing: They wanted one cozy “getaway” room where they could relax, watch TV, read, or just talk.

So they converted one of the three bedrooms into a cross between a small entertainment room and an old-fashioned den, complete with wood paneling, big-screen TV, wet bar with a small sink and refrigerator, large chenille couch, club chairs, and other items to give the room a relaxed feel.
