After the period of the Three Kingdoms Korean transportation architecture had been changed from the characteristics of the administration organization supporting the kings ruling system and gradually the characteristics as transportation architecture had cleared and diversified in accordance with the functions and characteristics of it. With this it was found that Korean transportation architecture like YukSa(驛舍), ChamYuk(站驛), GaekSa(客舍), JinSa(津舍), DoSa(渡舍), WonWoo(院字), JuMak(酒幕) and etc. had been developed variously and the architectural characteristics had developed with the functions and characteristics of transportation architecture. Some of them ,for example YukSa, ChamYuk, GaekSa, JinSa, DoSa, had the characteristics of the government office, so they had fundamental dignity of Korean wooden architecture on tile roof. But the WonWoo which was used by all of the people from the king to the people, had the characteristics of half-government and half-private. And the space of WonWoo was divided by the social position, the sex and the difference of temperature between summer and winter. And it was mostly located at the place away from the haunts of men, the form of it was the mud wall hut of the straw-thatched cottage like Sinhyewon of Mungyungsaejae and it was different from the station building of the characteristics of government office.
