One aspect that characterises the twenty-first century is its accomplishments such as better health-care systems, improved economies, a reduction in infant mortality and a growing number of adults living longer. However, these accomplishments can have a downside. For example, people are living longer while at the same time dementia rates are increasing significantly. With the increase in demand for high-dependency-related services, while at the same time costs are spiralling possibly out of control of societal budgets, there is a need for a shift in the care model. Additionally, difficulties in defining a clear dividing line between normal ageing and pathological ageing have led to a stigmatisation of older adults as a social and economic burden. This type of segregation and stigmatisation must be addressed to ensure future care delivery is inclusive. The positive benefits of an inclusive care system are both social and economic, and at an individual level it can positively impact upon an older adult’s mental and physical well-being. Taking this into consideration, the aim of this paper is to describe and empirically explore Humanitas© in Deventer, the Netherlands, a nursing home with a population of 50 older adults with dementia, 80 people with severe physical suffering, 20 people with social difficulties, 10 people in short stay for recovery and 6 university students. This analysis will be adopted as a ‘tool’ for the definition of a new way of conceiving architectural types in contemporary culture, based on the concept of an ‘open system’ described by Richard Sennett. In this study, an open system is able to promote a new paradigm of care built upon inclusive collaboration and teamwork between different categories of health-care providers, volunteers, residents and their families. This will allow an alternative paradigm of older adults’ long-term care and its architectural correlate to ‘normalise’ ageing and its related mental and physical impairments, rather than to ‘medicalise’ and stigmatise.
