Over-mount corner

An exterior wall of a building forming a corner at one end thereof with a generally orthogonally extending second exterior wall comprising:

• a building substructure including a layer of exterior sheathing material;
• a layer of wall panels having an exterior surface simulating an exterior surface of a building and attached to said sheathing material, said wall panels having a terminus end corresponding to said corner, said terminus end being located at a distance from said corner such that said sheathing material is exposed between said terminus end and said corner;
• and
• a quoin formed of at least one corner unit having a decorative exterior surface and a rear plate oriented in generally orthogonally extending faces, said decorative exterior surface defining a plurality of simulated masonry units extending outwardly from a rear plate portion, a relief space formed between adjacent simulated masonry units and defining a simulated joint, each orthogonally extending face of said rear plate including a plurality of standoffs projecting rearwardly from said rear plate and engaging said exposed sheathing material between said terminus end and said corner, each said face having a lateral width sufficiently large to overlap corresponding said terminus ends of said wall panels when attached to said exposed sheathing material;
• and each standoff aligned with one of said simulated joints on said decorative exterior surface.

A method of forming a decorative corner on an exterior wall of a building comprising:

• mounting a quoin formed of at least one corner unit at a corner formed by two generally orthogonal external walls of a building, said external walls including wall panels attached to an exterior surface of sheathing material such that a terminus end of the wall panels is located a distance from said corner thereby exposing sheathing material, said at least one corner unit having front decorative simulated surfaces joined at an intersection and rear plates, each said rear plate including a plurality of standoffs projecting rearwardly from said rear plate to engage said sheathing material between said terminus end and said corner;
• wherein said front decorative simulated surfaces define a plurality of simulated masonry units extending outwardly from said rear plate, said simulated surfaces mimicking an exterior surface of a building and providing a decorative appearance;
• wherein a relief space is formed between adjacent simulated masonry units, said relief space defining a simulated joint;
• and
• wherein each of said standoffs is aligned with one of said simulated joints on said simulated surface.
