Who says that interior design is suited for residential, commercial and artistic buildings only? We found out that even a mental health clinic can look exceptional and leave us with a fantastic feeling of creativity and playfulness. Located in Akasaka, Tokyo, Japan, the MD.net Clinic offers services such as psychiatrist consultations or corporate consulting and support for patients rejoining the workforce. Designed by Nendo, the clinic features many apparently hidden doors – the doors lined up in the hallway do not open, instead, the walls are the ones that open to reveal other rooms. Even the consultation rooms have sliding bookcases as doors. This new perspective on things helps patients put aside any preconceptions they might have about space or real life and encourages them to look beyond the appearances.
