A secure deposit box and method of construction thereof are presented. An inner door is affixed to a top inner surface of a housing and movable on a top edge around a sphere of rotation defined by a bottom edge. An outer door is affixed to a front side of the housing and moveable on a bottom edge. A connecting member is attached on one end to a side edge of the inner door and on the other end to a corresponding side edge of the outer door. An inner panel is fixedly attached to the bottom edge of the outer door, moveable on a proximal edge in the same direction as the outer and inner door, and has a distal edge defining a sphere of rotation which is distinct from the sphere of rotation for the inner door. No overlap exists between the inner door and the inner panel.
