I grew up in Miami, where it's not unusual to have one seamless tile floor extend around to and through every room in the house. It wasn't until I moved away that I realized, one: tile bedrooms are a little strange for the rest of the country and, two: people have many different needs for many different floor coverings in their homes. Sometimes even in the same room.
"God," German architect Mies van der Rohe once famously said, "is in the details." It's hard to imagine more beautiful details than these eight boundaries where two flooring surfaces meet, marrying different materials in innovative and elegant ways. If you decide to imitate these transitions in your own home, don't be surprised if everyone spends all their time looking down.
