Concerning the built environment, some spaces in and around buildings symbolise the edge and intercommunication between two opposites and are therefore difficult to define. These so-called in-between spaces represent a threshold between polarities, such as inside and outside or private and public. The Harbour Police Station in Rotterdam consists of three buildings and has multiple inbetween spaces, which include several entrances, doorsteps, windows, dormers, balconies, and a fenced perimeter. Since the new program will be more publicly oriented, the in-between spaces of the redesign need to attract passers-by, rather than obstructing them. Based on literature, archival drawings, personal observations and questionnaires, the influence of the materiality on the perception of in-between spaces is analyzed. Accordingly, the human perception of a building façade, entrance or window that attract passers-by can be expressed through perceptive descriptive qualities such as friendly, inviting, and pleasant. The research shows that this is influenced by the warmth, openness, and lightness of the in-between spaces. A warm materiality is perceived as pleasant and comforting and it indirectly excites to go inside. Furthermore, either big or many openings will create a more transparent building, that matches with public functions. Namely, the function should be clear on the outside. In line with this, an open façade and enough lighting contribute to a better visibility and draw attention to the building and its interior. Accordingly, it is particularly important that one can easily understand where and how one can enter. In summary, the materiality of the inbetween spaces contributes to the experience of the appearance and the perceived function of the building. In the case of attracting buildings, the inbetween spaces should be represented by clear accessible entrances, multiple or large windows, and warm colours, materials, and lighting.
