The largest of the home’s 11 displays is a 103-inch Runco plasma TV. Weighing a quarter of ton and costing around $100,000, it deserved a place all its own. Rather than sequester it to a dedicated theater room, the family had it installed in a more accessible “movie lounge” area. Located between the kids’ and parents’ bedrooms and designed for casual viewing, the lounge is used far more than a formal theater.
