This is more than you will want to know about a traditional Korean house. It is something I prepared for my Korean culture class. Power Point is still very laborious for me so this was how I chose to put it together. Feel free to skip it. There will be no test.
For nearly 1400 years Korea has been a separate, distinguishable country with borders similar to that of North+South Korea today. This long life in the same place has allowed Koreans to develop unique cultural elements including homes that endured for centuries.
The firebox was fired by wood which would need to be prepared for a long winter:
Traditional Division Into Rooms
a second room for the children, one or more common rooms
and one or more rooms for guests. A kitchen would be connected with the firebox of the ondul. A large vessel outside and above the firebox would be an important source of hot water and be used for some forms of cooking.
Some houses would have rock basins to catch rainwater or for culinary purposes...
While Koreans are now housed largely in modern high-rise apartments in cities, the traditional Korean house has come to be honored and appreciated for what it was: an environmentally astute, practical and beautiful expression of an enduring culture.
