From 2014 by the beginning of 11th government, a new period of conservation was started by establishing a new conservation policy, planning and implementation of built heritage in Iran. Cooperation between the Ministry of Road and Urban Planning and Cultural Heritage Organization created a basis for introducing a new approach by providing a national urban regeneration policy which was approved by the government. Based on this national policy, a number of plans and program was started to improve the quality of life in the Iranian cities. One of the key elements of this planning policy was the conservation of built heritage which was neglected for a long period. Adaptive and creative reuse of cultural heritage was the main policy for conservation of various built heritage. Modern Architectural Buildings as an asset which remain from two distinguish periods (Late Qajar & Pahlavi Dynasty Periods) were the amongst of these buildings that planned for safeguarding and reusing by the new clients. This paper intends to review the policy documents, conservation plans and main implementation programs in this period. Two case studies in Tehran and Isfahan (Vartan House & Risbaf Factory) will introduce as the representatives of group of modern heritage that planned to conserve and reuse for the next generation. The result of this investigation shows that conservation of modern built heritage can be a catalyst for the regeneration of wider urban area. The capacities of these buildings and complexes (location, spaces, architectural type and details, …) for adapting and reusing of variety of functions are the privilege of conserving modern built heritage.
