The foundation of this research lies in the social experience of living together and how architecture can contribute to a more profound sense of belonging. What began as a curiosity about the social potential of shared space evolved into a broader exploration of how people form relationships, with one another, and with their environments. Rather than focusing on housing as a purely functional solution, the project considers how feelings of ownership, recognition, and comfort emerge through design. These aspects are explored across multiple scales: from the city and building to the corridor, doorstep, and living room. The project examines how collective and transitional spaces can become active zones of community-building when spatially and socially considered. Through design strategies such as clustering, varied access, and interaction zones, the architecture fosters a resilient framework where people not only live but also connect, engage, and belong. Ultimately, this research highlights how architecture can support resilient, inclusive communities through spatial design that responds to both personal and collective social dynamics.

This study investigates the evolving role of the health and wellness centre Sanatorium Baarn, designed by H.P. Berlage and T. Sanders, through the lens of changing public perception over time. The inquiry is grounded in the central question:
'To what extent has the public reception of the health and wellness centre Sanatorium Baarn, designed by H.P Berlage and Theo Sanders, evolved over time and which factors within and outside the design process have influenced this interpretation and evaluation?'

The Sanatorium, envisioned by H.P. Berlage and T. Sanders, aimed to rival European health centres ('Kur') and establish itself within Baarn's community. Surprisingly, it exceeded expectations, becoming a haven for both the rich and ill. Initially embraced, the Sanatorium's architectural intricacies were cherished by the community. Its significance persisted, endorsed by figures like Sergio Polano. However, a gradual transformation unfolded. Neglect, complexities in ownership, wartime disruptions, and post-war decline marred its splendour. Despite rehabilitation, guest numbers dwindled due to factors like car-free days, necessitating closure. Evolving fire safety standards posed further challenges.

Amid these changes, public perception endured, keeping it a cherished symbol. Post-war shifts made it political, transitioning into a facility for war victims (BAVO) and Indonesian repatriates. An arson attempt damaged the structure's integrity, but hope remained for revival. After an auction, the building teetered on a second chance, poised for restoration. The city council, eager to preserve it, oversaw demolition and transformation. Yet, challenges arose with the new design by Van den Broek and Bakema. Municipal decisions and communal functions significantly influenced its trajectory. Ultimately, interventions altered its status, reflecting architectural resilience amidst historical shifts.
