A loading wharf includes a compact structure secured to the perimeter of an access opening formed in a wall of a building. The compact structure defining between the inner and outer faces of the wall, an intermediate space for placement of protective members and a folding ramp both of which move between an operational position in which protective members and ramp project from the intermediate space towards the outside, in order to interact with the body or trailer of the vehicle to be loaded or unloaded, and a non-operational position in which the protective members and ramp are positioned inside the intermediate space and are oriented vertically. The compact structure includes, corresponding to the outer and inner faces of the wall, frames for the mounting of an exterior closure door and of an interior door.
