ABSTRCT - The architecture of Rattanakosin Island, conserved or deserted, has always been conserved by the governmental authorities. However, one of the inconvenient truths which is always overlooked is the potentials and creative ideas of local communities and the youth. In fact, the local participation in architectural conservation can not only develop the art appreciation among the young and the economics but also bring Rattanakosin back to life. In fact, the development requires the attention in Thai uniqueness and the wisdom of Thai artisan in terms of knowledge and techniques for Thai design. The traditional Thai designs are improved and widely publicize to young generation and foreigners until they are integrated into Thai modern designs and become more interesting and unique. The premise of the concept that “The timeless beauty integration for the development of originality” is the bridge between the beauty of the past and the present which results in the legendary design with individual and national value because the contrast between two qualities can enhance their own uniqueness to be more distinct.
