Homes in Ireland are much smaller than Canadian homes. So, the whole idea of a house with a den, formal living room and separate media room seems strangely excessive to me. Of course, this is compounded by the fact I live alone and don't share my space. My ideal living room is a combination of all three, walls of books, chic enough for company, homey enough to just lie on the couch and nap.
