Chapter 3 explores how contemporary housing design can shift from individual ownership toward collective, community-centered living models. It highlights both conceptual proposals and real-world projects that prioritize shared spaces, flexible housing, and active resident involvement in shaping their surroundings, especially in response to increasing urban density and environmental concerns. These ideas are further developed through explorations of modular design, mixed-use environments, and inventive communal layouts. Ultimately, the chapter presents architecture as a key means of addressing housing inequality, fostering stronger social connections, and reimagining urban living as a collective good rather than an individual pursuit.
