Traditional Korean Houses

I want to introduce traditional Korean houses. The first one is a thatched house; it was a common house 100 years ago. Recently it isn't used in Korea. If you go to a Korean Folk Village, you'll see it. The next one is a tile-roofed house; it wasn't a common house 100 years ago, for it was very expensive. Now some people live in a tile-roofed house beause most people live in a ferroconcrete building. My grandmother lives in a tile-roofed house, but I don't want to live in that kind of house since that kind of house isn't convenient. I think Koreans need to protect these kinds of traditional houses.
