Actor Wonbin's house that he built for his parents in Jeongseon, Gangwon Province has won the 2008 Korean Architecture Award. The house is about 4,200 square feet and features a unique design. The second floor of the house has no livable space (just some stairs), the house goes directly from the first to the third floor. The reason behind this is because the concept of the house was a hill, so they wanted a high vantage point to take in the scenery / nature surrounding them. According to KBS Global:

Apparently, Won Bin showed a photograph of Jennifer Lopez's Beverly Hills mansion to architect Kwak Hee-soo, and also asked him to incorporate memories of his old childhood home in Gangwon Province into the design. The kitchen is adorned with red bricks and features an old-style cooking-range that can heat the floor of the guest room.

The house looks tremendous from the outside, too bad there are no interior pictures. It's a nice gesture for Wonbin to do for his parents. I hope one day I'm rich enough so that I can do the same for my own parents.
