The invention involves a method for converting a cabinet into a wheelchair accessible space, involving a retractable shelf with anterior, intermediate, and posterior panels. The method includes detaching the anterior panel from the cabinet's support component by removing a screw, folding the anterior panel towards the cabinet's posterior, and laying it parallel on the intermediate panel. Subsequently, the intermediate panel is folded onto the posterior panel, with the anterior panel stacked on top, revealing a wheelchair accessible area. The retractable shelf, initially in an expanded position, features hinged connections allowing parallel folding of the panels. The method is designed for universal installation within the cabinet, obviating the need for complete de-installation or re-installation.
