Purpose: Post conflict housing reconstruction is crucial to development and peacekeeping. However, the success of it is hindered by a number of problems related to lack of addressing housing needs. This paper explores how such housing needs can be effectively managed in post conflict housing reconstruction in Sri Lanka. Design: Using the grounded theory method as the research strategy, unstructured interviews were conducted with policy makers, practitioners, beneficiaries and academics in Sri Lanka. Data were analysed using open, axial and selective coding to develop the theoretical framework. Findings: The study reveals the challenges, contributing factors and strategies in addressing housing needs of accessibility, habitability, affordability, location, facilities, cultural considerations and security of land tenure. It also identifies the gaps and recommendations. The paper establishes the links between these and presents a theoretical framework for managing housing needs effectively in post conflict housing reconstruction in Sri Lanka. Implications: This research enhances the success of post conflict housing reconstruction through addressing housing needs effectively, which contributes to sustainable housing development after conflicts. Originality: The study combines literature from five main areas: conflicts, post conflict, post conflict reconstruction, post conflict housing reconstruction and housing needs and provides a better understanding on how the housing needs can be managed during post conflict housing reconstruction in developing countries based on empirical evidence.
