Why Dallas have Mediterranean Style Houses?

Is it normal that Dallas have Mediterranean Style Houses? Now the only Mediterranean style houses in Dallas is worth a million dollars and up, so they're luxurious, but I thought only places closer to the ocean (Florida, Southern Texas, and California) will have Mediterranean style houses. Dallas is more country and woody ( I love Dallas btw) to have Mediterranean style homes, plus, it snows in the winter and Mediterranean style homes don't belong in the snow. So can someone PLEASE tell me what is the purpose of Dallas having Mediterranean Style Homes! Thank You :-)
