This article addresses issues related to the typology of residential buildings for older adults. In response to changing social expectations, new types of facilities are being devel-oped, featuring innovative functional principles and diverse spatial configurations. The diversity of senior housing architecture is, among other things, a consequence of the growing interest in the challenges posed by an aging society. People are living longer and remaining in good health for extended periods of time. The later stages of life are heteroge-neous and encompass various phases of aging, which results in changing preferences re-garding housing needs. Research in this field contributes to the reevaluation of approaches to residential design and inspires the development of unconventional and experimental solutions.Current developments increasingly aim to respond to the actual needs of sen-iors. Architects and developers should therefore explore non-standard solu-tions to a greater extent and test more innovative housing models capable of responding to ongoing demographic transformations. Particular expectations are associated with concepts such as co-living and mixed-use “social-mix” environments, in which people of different ages can coexist. Solutions are also emerging that address the challenges of ageing in combination with other aspects of everyday life, such as creative co-housing or care-sharing house-holds. The situation remains dynamic, and the design process requires contin-uous updating and development. It can therefore be assumed that models of residential environments for older adults will continue to evolve. Undoubted-ly, this field represents an important research and design challenge for contemporary architecture.
