This work was installed next to a wheelchair elevator. Of course, accessibility should always and everywhere be the standard. Still, this specific elevator looked misplaced in the gallery because of its standardized hospital-like design. It had a white medium height door.
Next to this door I installed a pet door for medium sized pets with a mirror behind it on the wall. It resembles as an appliance the wheelchair elevator door, so it is not noticed at first sight. The mirror creates the illusion of an actual pet sized passage into another space, only accessible for medium sized pets, like cats.
