This publication wants to transmit the constant values of the Seung H-Sang's architecture, which has been routed on principles and ideals driven by sensuous and essences of raw materials, echoing the extemporal features of the culture where buildings are placed, discovering the prettiness of scarcity of resources. IROJE's buildings, landscapes and urban proposals have been always looking for the equilibrium between endurance of the past essence of each place and the freshness of the new life experiences generated by the architecture. The book proposes to compile the best architectural IROJE's works employing the magnificence of black and white pictures, creative sketches, and elementary plans and drawings to illustrate the permanent values of Seung H-Sang.
