A few weekends ago I was at a spot on the northern coast and found a cluster of UFO shaped beach houses. I don't remember the name of the place right now but I will look it up.
I had no idea this was some sort of a strange architectural trend in Taiwan. It's too bad the ones on your photos no longer exist, would love to visit them.
I plan to go back to take better photos of these with an SLR camera and write an article about them. Will keep you posted.
