Moveable edge scaffold

A scaffold apparatus, comprising:

• a vertical structure having a first and a second tubular elongate vertical member, each tubular elongate member having a front side, an opposing back side, an inner side and an outer side, a top end and a bottom end;
• an upper horizontal structure having a first and a second horizontal elongate member each having a length, each of the first and second horizontal elongate members attached at opposing ends of the vertical structure orthogonally to the back side proximate the top end and extending in a first direction over a surface;
• a first crossbar having a first length, the first crossbar connected orthogonally at one end of the vertical structure proximate to the bottom end at the inner side of the first vertical member and connected at a second end of the vertical structure proximate to the bottom end and the inner side of the second vertical member;
• and
• a platform structure having a third and a fourth horizontal elongate member each including a length, each of the third and fourth horizontal elongate members attached orthogonally at the front side and the bottom end of a respective one of the first and second vertical members, extending away from the vertical structure in a second direction opposite the first direction of the first and second horizontal elongate members;
• wherein the length of the first and second horizontal elongate members and the third and fourth horizontal elongate members are substantially equal in length, the first and second horizontal elongate members lying flat on the surface that extends from an upper edge of a walled space and extends from the vertical structure downward into the walled space, the back sides of the first and second tubular elongate vertical members are adjacent to a wall of the walled space, and the platform structure extends from a lower end of the vertical structure into and away from the wall of the walled space, providing a support surface for a user to stand upon to perform maintenance on the wall proximate the vertical structure,
• wherein a ring-shaped attachment interface is positioned at a distal end of each of the first and second horizontal elongate members such that the upper horizontal structure is configured to be anchored to the surface that extends from the upper edge of the walled space by placing one or more stakes proximate to or through each said attachment interface.
