This research is focus on conserving of the historic buildings and its surrounding environments in Pyin-­‐Oo-­‐Lwin town.

During 19th Century, British made well plan with impeccable signs of urban planning and local architecture and built the many famous buildings in Pyin-­‐Oo-­‐Lwin town. These colonial buildings are standing now as heritage buildings and structures so that targeting conservation resources towards particularly vulnerable group of sites and environments. Because of elevation, situation, climate and verdant environment, it be comes prominent as a famous highland town. In urban areas, increased attention must be paid by the institutions for its conservation; new issues have to be addressed, due to the dramatic changes occurring. It suffers from physical and functional decay and seems to have been seriously affected by inconsistent development. The historic architectural and urban features of Pyin-­‐Oo-­‐Lwin deserve a careful survey and assessment, in order to be protected as a substantial part of Myanmar heritage. It involves actively caring for the heritage, maintaining it in good physical condition, making it readily accessible for study, enjoyment, recreation, and tourism. In this research, it is thoroughly documented the existing conditions of Pyin-­‐Oo-­‐Lwin town and identified the possible heritage areas to be conserved with the development of this town. Then, the study on the principles and methods of conservation and criteria for conservation are presented as literature study to support this research. Finally, this research intends to give general guidelines for existing historic buildings and new buildings built harmoniously in the environment and to create encouragement and promote heritage awareness on historic built form of Pyin-­‐Oo-­‐Lwin Town.".....Paper delivered at the International Conference on Burma/Myanmar Studies: Burma/Myanmar in Transition: Connectivity, Changes and Challenges: University Academic Service Centre (UNISERV), Chiang Mai University, Thailand, 24-­26 July 2015.
