A pair of extension ladders are arranged in spaced, paralled vertically upright position. Diagonally extending cross braces extend between and are secured to the ladders to hold the ladders in upright position. A pair of wheels are provided on the bottom of one of the ladders to allow the scaffold to be easily moved by lifting up the other ladder. Hooks are provided on the ladders which fit into eyebolts on a building to hold the scaffold in position next to the building.
