The term "in-between space" describes semi-public and transitional spaces found in urban housing projects that operate as essential linkages, encouraging communication and a feeling of community among occupants. These areas, which range from lobbies and common areas to courtyards and corridors, are vital in forming the social fabric of urban living spaces. Rethinking spatial design in ways that foster social cohesiveness, increase well-being, and enhance overall living experiences is becoming increasingly important as high-density housing construction is driven by rapid urbanisation. This research explores the ways in which the layout of interstitial spaces affects user interaction and strengthens the social ties within urban high-rise dwellings.  The study assessed the layout, usability, accessibility, and general effectiveness of these areas in fostering social interaction by looking at case studies and surveying inhabitants of different urban housing projects. The incorporation of traditional Malay home features into contemporary high-rise settings is a crucial component of this work. The openness, well-planned common areas that promote social interaction, and harmonious integration with nature are characteristics of traditional Malay dwellings. Wide eaves, elevated platforms (pangkin), open verandas (serambi), and natural ventilation are examples of architectural elements that provide hospitable common spaces that improve community involvement. This study offers creative methods for rethinking third space as semi-public communal spaces that act as a mediator between private homes and completely public places by translating these components into modern urban living. This research focusses especially on corridor design, investigating how conventional architectural ideas might be modified to enhance the space's usability, aesthetic appeal, and capacity to promote neighbourhood connection. The study examines how culturally inspired design interventions might turn corridors from uninspiring passageways into lively social centres that promote group interaction through data-driven analysis
