Group 1: Design Innovations - The fourth-generation residential properties have gained market attention due to advantages such as high usable area and innovative sky gardens, but they also face challenges related to privacy due to visual interference from neighbors [5]. - The Chongqing Haicheng Yunhu Jun project employs a unique vertical space planning strategy to resolve the issue of visual interference between floors by offsetting the terraces of odd and even floors and incorporating solid walls above the terraces [7][20]. - The Chongqing Longfor Yuhujing project introduces a "floating courtyard system" that optimizes traditional end-hall layouts, ensuring privacy while maintaining natural light through strategic design [14][17]. Group 2: Privacy Solutions - The design of the Chongqing Haicheng Yunhu Jun includes a central placement of odd-numbered floor terraces, which are shielded from neighbors by the master bedroom, while even-numbered terraces are surrounded by garden vegetation, providing a natural visual barrier [10]. - The Longfor Yuhujing project features a layout that allows for two-sided lighting while avoiding visual interference, with solid walls strategically placed to create visual blind spots for upper neighbors [17]. - The innovative practices of both projects demonstrate that privacy issues in fourth-generation residential designs can be effectively addressed through optimized layouts, appealing to customers with high privacy requirements [20][21].
