Forensic hospitals provide care for incarcerated patients who have committed a crime under the influence of serious mental illness. The care and (re)habilitation of the target group require highly competent staff and treatment strategies as well as purpose-built facilities that promote successful recovery. The aim of this study was to examine patients' experiences of place and space in new, purpose-built, evidence-based designed forensic psychiatric facilities in terms of supporting everydayness. A qualitative methodology was chosen. In total, 19 patients agreed to participate. Data were collected through photovoice (a combination of photographs and interviews) at three forensic hospitals, according to an evidence-based design and the concept of person-centred care in Sweden. The data were analysed through thematic content analysis. Four themes emerged from the data, revealing the patients' experiences of the new buildings: (i) having a private place, (ii) upholding one's sense of self, (iii) feelings of comfort and harmony, and (iv) remaining connected to one's life. The findings reveal that purpose-built environments can support everyday living and well-being and can create comfort. This is considered highly therapeutic by the patients. In conclusion, the findings of this study are of imperative importance in the design of health-promoting forensic hospitals. © 2021 The Authors.
