In the life style of the neolithic age, cooking and sleeping space was in one room dugout without differentiation of spaces, so to say one room system. Ro(a kind of primitive fire place) was used for both cooking and heating. However, in the early part of the Iron Age, the uses of Ro were separated into two major uses of cooking and heating. Especially, L-shaped Kudle(an unique under floor heating structure of Korea) was invented for the new system of heating, extending to Koguryo Period. The life style of Koguryo Dynasty could be seen through the mural paintings of tombs. For these mural paintings contain of cooking space(Kitchen), meat storage, and mill house drawing, we can recognize that houses were specialized many quaters according to their function. Also a kitchen fuel hole for preparing food was built without relation to L-shaped Kudle. But during Koryo Period, Kudle could be set up all over the room, the so-called Ondol(the unique Korean panel heating system) settled down. From this development of heating system, room could be adjacent to kitchen, and kitchen fuel hole and heating fuel hole be onething. This system was developed with variety, extending to Chosun Dynasty. In the period of Chosun Dynasty, a kitchen was made close to an Anbang(Woman's living room), and Anbangs Ondol was heated by the warmth of a cooking fireplace. Therefore Handae Puok, outer kitchen was used in summer. As for its storage space, it was seen that there were a pantry near the kitchen and a store house constructed as an independant building. In the latter, it was devided into a firewood storage, a Kimchi storage, and a rice storage, etc. Especially it is a unique feature that 'Handae-Duyju', an outer rice chest which keeps rice, was constructed as an isolated small building.
