Abstract: This prefabricated locking quoin block is used to construct the surface of buildings. The surface of the block has decorative portions resembling brick, stone, wood, or other construction materials. Preferably the surface of each block has both a raised and a recessed decorative portion, so as to form, when assembled, a quoin corner assembly resembling sawn or quarried stone blocks. Installers can attach the assemblies to conventional building structures and install cladding materials such as vinyl siding without needing to alter the blocks other than to adjust the base block for height. The block includes wedge locks to securely connect adjacent blocks matingly to each other. Installers thereby are able to assemble a secure stack of quoin corner blocks and attach it to a building with few additional steps, saving time, labor, and cost in construction.

Abstract: A prefabricated vinyl-siding corner block is provided for use as a corner on a building. The vinyl-siding corner blocks have raised portions that are formed to resemble structural building materials such as brickwork, stone, wood, stucco, or other materials used for surface elements of buildings and recessed portions formed to resemble a stone surfaces of a course of mortar or cement. The vinyl-siding corner block is preferably formed to have the appearance of stone blocks with a quarried, sawn or sculptured appearance. The vinyl-siding corner block is formed to facilitate interaction with readily available conventional siding materials and may be readily attached to the frame of a building with the minimum of tools and labor and thus contributes to the achievement of a relatively low construction cost.
