Architecture represents a creative, high profile and influential profession and yet remains under-theorized from a gender perspective. This article examines how gender is (re)produced in architecture, a profession that remains strangely under-researched given its status and position. The empirical work advances the theoretical concept of hegemonic masculinity via an analysis of gendered working practices and the agency of individuals through resistance and complicity with these norms. It reveals how architectural practice relies on long working hours, homosocial behaviour and creative control. However, whereas women perform their gender in ways which reproduce such gendered norms, white, heterosexual, middle class men can transgress them to challenge aspects of practice culture. This has significant implications for understanding the ways in which hegemonic masculinities are reproduced within creative workplaces.
