Based on fieldwork in Danish children's homes, this article examines how the idea of 'home' has emerged and become integrated in institutional practices. The ideal of hominess serves as a positive model for sociality in the institution, but at the same time it also produces dilemmas, paradoxes, and contradictions for both children and social workers. These dilemmas stem from the conflicting values of institution and home. Nevertheless, the two spheres should not be seen as spaces with incompatible logics; rather, they should be viewed as mutually dependent but competing ideas (and practices) that are inherent in the institutional value hierarchy. The article argues that the ideal of authenticity plays a central role in the way that hominess is perceived as a positive value in children's homes—and perhaps in institutions in general.
