当代住宅建筑正面临全球住房短缺与城市人口持续增长的迫切挑战。在建筑实践中，人们反复尝试新型集体居住形式，致力于为个人、家庭及社区发展提供空间支持。本文所呈现的六个未建成项目，展现了密度提升决策的多重维度：与既有及规划中自然环境的关系、城市或郊区土地的可获得性、支撑集体生活并缓解高密度体验的补充性中间空间的营造、密度提升模式的可复制性，以及与容纳人口增长的周边社区之间的关系。

Contemporary housing architecture faces the pressing demands of the global housing deficit and growing urban populations. In architectural practice, we see recurring experimentation with new forms of collective living, taking on the task of offering spaces for personal, family, and community development. The six unbuilt projects presented here show us different facets of the decision to densify : the relationship with pre-existing and planned nature, the availability of urban or suburban land, the development of complementary intermediate spaces that support collective life and ease the experience of density, the replicability of densification models, and the relationship with the neighborhood that accommodates population growth.
