Of the recent HGTV shows I think Property Virgin shows it best where you have a young couple/or single who wants to buy their first home. All love the charm of the craftsmanship, the high ceilings, the crown moldings, the wooden floors but they all squeak at the small bedrooms, small kitchens and small bathrooms. In some of the older homes opening the living, dining and kitchen areas really adds to the home. Hidden Potential does this best. It says much about how our lifestyles have changed and how homes need to be adapted to suit the current lifestyle. It also goes to that old adage baths and kitchens sell houses. Still I do argue the point if you have the place to yourself it is not that important to have the biggest bedroom because you do have a living room and the rest of the apartment/house to yourself. I think alot of people want a huge bedroom and closet so they can store all their stuff. Basements are wonderful things. If you have one you don't necessarily need that huge walkin closet.
Oh, it didn't help for the longest time when the furniture manufacturers made huge overstuffed furniture that looked overscale even in a 2,000 sq ft home. What a relief it was when they started to scale the furniture back down.
