This bachelor thesis focuses on the design of public space appropriate for girls in terms of female processes of appropriating public space. Specifically, the social environment represented by public parks is described. Male socialization is a further aspect considered here. Both „gender mainstreaming“ in urban plan-ning and gendersensitivity in structuring spaces for youth are referenced in this paper to support the process of developing a guideline for girls' public spaces, with the aim of reinforcing interdisciplinary cooperation. Additionally, professional focuses in the project are defined by expert persons and institutions from the fields of youth work, youth work with girls, and spatial planning. In the course of the paper, options for spatial planning that are appropriate for girls are elaborated upon, and a structured summary guideline is presented.
