Housing Bubble 2: Return of the Ugly

It's really dependant on how the layout is. Generally 1500sqft isn't a problem however if it has 5 rooms squeezed into the house it begins feeling cramped especially if you have a large family. I have 1800sqft and the first floor has plenty of space but upstairs has a low ceiling (6.5ft) and about a 2ft wide hallway leading to 2 full bedrooms, a full sized bath, and a small guest room that's only slightly bigger than a broom closet. There isn't a way to have rooms downstairs so I consider my upstairs cramped but my overall living conditions fine. Now imagine a single floor utilizing that space needing just as many bedrooms and it begins getting cramped with the kitchen, living room, dining room.
