“…Recognizing the importance of shared open spaces for developing social connections among occupants in high-rise buildings, Ghazali et al promote the "sky neighborhood" concept; they propose a new kind of arrangement with accesses to each apartment via six-story-high landscaped courtyards, in this way eliminating corridors and improving the social and environmental quality of intermediate spaces in high-rise housing buildings [40]. On the other hand, in cases where potential meeting spaces are lacking in the housing environment, opportunities for casual encounters among residents are weak; thus, Bektaş and Taşan-Kok notice that individual entrances to housing units are the subject of most occupants' complaints about neighborly relations, as they could at least meet someone unexpectedly in the common hall [2]. Speaking about specific solutions for the built environment from the perspective of social interactions during the COVID-19 pandemic, Pinheiro and Luís give several suggestions for common spaces in buildings: widening of circulation spaces and entrance halls, existence of external spaces (balcony, terrace, flat roof) accessible to all residents, natural lighting and ventilation, favoring minimalist design and the use of easily washable equipment and materials [23].…”
