Abstract: This research of technology development for Hanok will study for large space Hanok over lOmeters, the New Hanok style public building, the residential efficiency upgrading about "Technology Development of Design and Construction for Large space Hanok over lOmeters." The technology development for large space Hanok will maintain the traditionality and will develop long-distance intercolurnniation over 1 Ometers through modem technology development. Also, the technology development for large space Hanok will develop the structure for the New Hanok style over 10 meters high and optimal construction technology. Moreover, the technology development for large space Hanok will standardize the developed large space Hanok technology. The New Hanok style public building will succeed the value of Hanok and technology and material will be free to use. So, the New Hanok style public building will be the public building constructed as modernized Hanok. And the New Hanok style public building will maximize the social ripple effect by satisfying the ease of user and various functions . Before, Hanok building and that sort of thing was established through the development of elements technologies of Hanok and test construction in the residential efficiency upgrading of Hanok. From now on, the existing constructed elements technologies of Hanok and test construction will be monitored for administering and improving and will make the related guidelines, effective maintenance and management system. Thus, this research expects the spread of Hanok and industrialization of Hanok through the application expansion of Hanok. Keywords : Large Space, Multi Layered,
