No, that doesn’t necessarily mean a TV room designed to look like Batman’s hideout, though that would be pretty darn cool. Rather, it’s a dedicated viewing space with an HD projector, plush theater chairs, and dark walls and furniture that will reject ambient light. There should be no windows in this room.
Professional home theater installers have been seeing a trend away from dedicated theater rooms, in favor of multi-purpose “great rooms.”"
