The value of the Tosi-Hanok have recently been appreciated and accordingly the resultant studies have actively been conducted. This is an attempt to probe our architectural type haying identity through our traditional architecture in Korean society that pursues only something new. But owing to the infusion of foreign cultures and modernization, the archetype of Korean-style house has either been damaged or indiscriminately transformed without the establishment of its proper norms. The understanding of the value of traditional cultures has gradually increased, and accordingly effort to preserve Korean-style houses through legal regulations or systems have continually been made in terms of appearance or cityscape. For this reason, it is thought that it Is insufficient to present the direction or alternative to preservation in relation to the change or use of the interior space with the pattern of requirement for other programs other than dwelling. Therefore, this study attempted to find out the original meaning of Korean-style house by highlighting the advantages of Tosi-Hanok and supplementing its disadvantage while accommodating the diverse requirement for programs as contemporary residential space. And it was intended to propose the model for Tosi-Hanok that accommodates social changes in content while maintaining its meaning by analyzing the Tosi-Hanok with a focus on interior space and preserving historical continuity on its basis.
