This paper investigates habitability in extreme environment habitats by examining how occupants contribute to the evolution of functional infrastructures into human-centered environments that support wellbeing. Through fieldwork at the Bulgarian Antarctic Base (BAB), the study combines architectural on-site observations with interviews, questionnaires, and participatory workshops. Three trends emerged from the combined material, highlighting the importance of regulating social interaction through semi-private spaces, the value of flexible spatial organization across work and leisure, and the role of personalization in supporting emotional stability, helping occupants claim the base as a lived habitat over time. By using occupants’ evaluations and spatial adaptations as evidence, the study informs design in a context rarely experienced firsthand by designers and proposes a participatory framework for assessing habitability in constrained environments already shaped by standardized planning and logistics. It offers an informed approach for translating lived spatial experience into qualitative interior characteristics.

Shared dormitories are the most common living arrangement for Chinese university students and have a crucial impact on their sleep and well-being. Most studies on sleep among this group primarily focus on the physical environment and the individual person, giving far less attention to the interpersonal and social aspects of living in shared dormitories. To address this gap, this paper presents the findings of a co-design workshop with 23 participants which explored their experiences of shared sleeping spaces and involved them in prototyping interventions for improving sleep experience. Findings reveal interpersonal interference as a major factor behind sleep disruption. Even though students experience negative emotions, they tend to adopt passive coping behaviours, reflecting conflict avoidance linked to broader cultural tendencies in Chinese society. This study also highlights the crucial role of interpersonal dynamics in shared dormitories, concluding that future design interventions should prioritise improving communication and consensus among roommates.

A large share of private rental housing in Flanders, Belgium, is unsuitable for older people who want to age in place, which can negatively affect their well-being. Since it is often unclear what changes tenants are allowed to make, this study examines landlords’ attitudes toward age-friendly housing adaptations and their impact on the tenant’s well-being through the self-determination theory. Using student-designed adaptations, exploratory interviews were conducted with five landlords. Our findings reveal landlords' negative attitudes frequently stem from the desire to protect their own well-being by avoiding potential hassle and property damage. However, this can negatively impact tenants’ feeling of autonomy and competence. Therefore, this research underscores that to design impactful, age-friendly adaptations, it's crucial to consider the well-being of both the tenant and the landlord. A focus on both may help create rental housing settings in which aging in place becomes a more realistic and sustainable option.

In high-density cities, window-view green walls (GWs) are implemented to improve psychological well-being, but their design often ignores context. Existing research overlooks how GW geometric forms interact with ambient urban soundscapes. This study investigates this critical audio-visual interaction. We conducted a 4 (sound: between-subjects) × 4 (visual: within-subjects) experiment in Virtual Reality (N=80). Participants were exposed to four visual forms (No-GW, Triangle, Square, Rectangle) within four dominating soundscapes (No Sound, Traffic, Conversation, Ventilation), reporting their Stress and recovery results. Results revealed a significant interaction effect, showing the optimal GW shape for psychological well-being was context-dependent: rectangular forms were best for traffic dominating soundscape, square forms for conversation dominating soundscape, and triangular forms for ventilation dominating soundscape. These findings demonstrate that green wall effectiveness is not uniform; design strategies must match geometric forms to the specific acoustic environment to maximize psychological benefits.

This paper investigates how generativity, understood as showing care and contributing to the next generation's lives, shapes visitors’ engagement, experience, and psychological wellbeing in the Hong Kong Space Museum. We conducted fifteen semi-structured interviews to explore how generativity unfolds in museum interactions. Building on Fan and Luo (2022), we extend the generativity model by introducing bidirectional and recursive relationships among generativity, engagement, and experience. Our findings show that generativity can be understood as a designable, relational and temporal pathway to wellbeing. Thematic analysis further reveals that different types of installations scaffold generativity and wellbeing through distinct design features such as low initial complexity, visibility of others’ actions, shared control, and layered annotation. These features enable visitors to guide, share, and explain, contributing to others’ experiences. The findings highlight museum design as a medium for situated wellbeing.

As office practices improve, green walls are increasingly deployed to ease work stress; however, research on whether their overall geometry yields differential individual effects remains limited.In this study, virtual reality was used to construct four office scenarios: curvilinear green wall (CGW), linear green wall (LGW), polyline green wall (PGW), and no green wall (NGW). Restorative effects after stress induction with the MAST were evaluated using two subjective scales, the fatigue scale and the restorative outcome scale. Results showed that all three green-wall forms significantly promoted post-stress psychological recovery at the subjective level. Further comparisons indicated that CGW produced the strongest effect, LGW ranked second, and PGW was relatively weaker. These findings suggest that although green walls generally provide positive restorative benefits, wall morphology is a key moderator in the recovery process, which leads different forms to show differentiated advantages across dimensions of psychological restoration.
