This interactive mixed-media installation investigates the boundaries between what can be accessed through clinical practice and what remains solely within the person’s own authority. At the centre of the work is an anonymised photographic portrait positioned within a large wall installation. Surrounding the portrait is a constellation of small handcrafted wooden doors, each representing a different dimension of the individual’s inner and outer life—identity, memory, embodied experience, emotional landscape, and medical reality. Several of the doors are intentionally designed to be opened by participants. Behind them, viewers encounter de-identified fragments of clinical material: portions of laboratory reports, medication charts, imaging snippets, and reduced clinical notes. These open doors symbolise the aspects of a person’s life that healthcare professionals typically access, interpret, and document through biomedical and diagnostic frameworks. Other doors remain locked, with no keys provided. Beneath the central portrait, a single sentence reads: “The key is with me.” The juxtaposition between what can be opened and what cannot invites reflection on the ethical dimensions of person-centred care. While clinical knowledge can illuminate biological patterns and measurable markers, there are personal truths—histories, meanings, vulnerabilities, and values—that remain inaccessible unless the individual chooses to reveal them. By requiring a large-scale wall installation, the work creates an immersive environment that asks viewers to navigate curiosity, uncertainty, restraint, and respect—mirroring the relational dynamics of therapeutic encounters. Participants are encouraged to experience both the permissions and the limits embedded in the artwork, recognising that genuine person-centred care depends not on accessing every door, but on acknowledging the person as the primary holder of their own keys. This installation shifts focus from “discovering the patient” to honouring the patient’s agency, boundaries, and sovereign right to decide which doors may open—and which remain closed
