"Hanok" Korean Traditional House

I'm from South Korea and I would like to introduce Korean culture to my classmates who came from different parts of the world. Korea has a very long history and there are highly sophisticated traditional cultures which have been maintained for more than 5,000 years. Today, I will introduce Korean traditional houses which are called as "Hanok".
The first and most essential feature of Hanok is the idea of co-existence of human and nature. Hanok was designed to harmonize with environments and to feel nature even inside of a house. Furthermore, it was built with various natural substances such as stones for basements, wood for pillars, doors and floors, and clay for walls.
Although most houses in Korea have modern style these days, there are still some villages where traditional houses are gathered even in Seoul, one of the most modern city in the world and some beautiful traditional houses are protected as cultural properties.
Many modern architects put high value on Hanok’s nature-friendly property and try to introduce this in modern buildings.
