This article examines young men's (aged 18 -25 years) meanings of home and practices of homemaking, comprising material and social relations. The discussion contributes to three areas of geographical interest: home, masculinities and youth. Both geographies of home and masculinities have begun to consider men's experiences and meanings of home, but young men's domestic practices remain largely unexamined. Geographical work on youth has examined housing transitions, but the gendered experiences of young men need further interrogation. To provide insight into young men's homemaking, this article presents qualitative case studies drawn from fieldwork that investigated relations between masculinities and domesticities in Sydney, Australia. Young men are arguably out-of-place at home in conventional discourses of gender and space, but homes are nevertheless crucial sites for shaping masculine subjectivities. Masculinities and homes are co-constituted through domestic practices, generating diverse intersectional subjectivities and spaces. In this article, three subjectivity-space, or masculine-domestic, relations are discussed, which also counter the centring of heterosexual couple family homes in domestic imaginaries: young men in parental homes, share-housing and 'alternative' family homes. I examine similarities and differences across and within these masculine domesticities. This multiplicity of 'youthful masculine domesticities' offers a set of qualitative examples for use in public rhetoric that seeks to redress uneven gender dynamics in contemporary domestic life.
