"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.
Once relegated to industrial lofts and warehouse spaces, concrete, as a flooring material, is finally starting to be appreciated for its raw beauty. It's nice and cool underfoot, wonderful if you live in a warm climate, and, as these 14 interiors prove, has a texture and variation that give it a special warmth all its own.
