Social gerontology mainly addresses couples' housing arrangements in later life by focusing on partner's care, related adaptations in place, and changing role expectations within the couple relationship. Thereby, the resulting image does not fully represent today's diversity of couples' housing arrangements.This article considers housing arrangement and relationship orientation of older couples as entangled in social practice, providing a broader perspective on the diversity and dynamics of couples living arrangements in later life.In a qualitative study, we conducted joint in-depth interviews with ten couples from Germany aged 58 to 88 years. Couples talked about their shared biography and living together today. Data were merged with fieldnotes on housing constellations and analyzed following the documentary method.Couples co-constitute living together by using space in different ways. We found three relationship orientations of couples corresponding to practices of couples' housing arrangements: balancing physical and emotional presence by negotiating shared space, exploring presence by having a third common place, and reducing presence by separate housing. These orientation types which are linked with spatial (re-) arrangements reveal positioning to housing preferences in past relationships and point to societal concepts of coupledom as regards housing in later life. Space gives options for both being apart from and feeling close to the partner, partially at the same time.Diversity and dynamics of housing arrangements correspond to diversified and altering relationship orientations in later life. Considering couples' housing arrangements in later life as mutually constitutive broadens the options to examine the meaning of space in aging together. Moreover, this perspective can be combined with a critical approach towards stereotypical (hetero-) normative biases in research.
