During the last couple of years, its movement has boosted by community- driven process supported by Community Organization Development Institute (CODI), public organization, initiating the program so called “Baan Man Kong”. The program emphasizes on community, considered as the core mechanism, to work at the very fundamental level in order to improve the living condition as well as secure tenure and conduct to formulate the myriad of local partnerships at the end. The objectives of the paper are twofold. The former is to summarize the experience on the community development process in planning and design regarding urban poor housing through four case studies in Isaan, the northeastern region, where the urban poor generate the lowest average income in Thailand. And the latter is to depict lesson learning from experience and knowledge which has been exchanging among communities, academic institutes and local administrative bodies. This lesson learning could shed the further light on urban poor housing movement from pilot community to the others. Meanwhile, empowerment has apparently been issued when the urban poor housing movement encourages the decentralization of decision-making power to community people. This is not only the relationship changing between local government and community, but also between the groups of leader to the dwellers. The outcome from field practice positively reveals the interactive learning and communicative action planning affecting to local empowerment. Three concerned indicators – the increase of new leaders, the emergence of new neighborhood clusters and groups, and the change of local administrative mechanism, would mirror a significant step towards urban poor housing sustainability through design and planning process.
