Low-cost settlement (LCS), also known as slums, is a prevalent feature of many cities across the world. These densely populated areas often accommodate a significant portion of the urban population, providing affordable housing for low-income residents. However, LCS can face challenges related to inadequate infrastructure, sanitation, and overall environmental quality. This study delves into the fabric of existing LCS landscape development in Sylhet City, Bangladesh that include overall built environment, vegetation, sanitation, waste management, layground for children, space for socialization, security and other service facilities etc. Using a mixedmethods approach involving data collection, image analysis, physical surveys, and questionnaires, the research explores outdoor landscape patterns, dwelling types, spatial morphology, and environmental conditions within these settlements. The investigation also focuses on the pattern used on the land surface, layout of circulation spaces, connectivity, and the socio-economic conditions of the slums within the Sylhet City Corporation area. Ultimately, this research aims to contribute to further studies on low-cost settlements at a regional or national level based on context, and to propose solutions to the challenges identified.
