Quoins are the rock blocks used at the corners of Georgian-style masonry houses. They were traditionally granite rectangles which were placed in an alternating pattern and functioned as a structural component to load-bearing walls. Now they’re primarily decorative and produced from any number of materials. Even foam can be molded into many shapes and glued into exteriors, developing a quoin that’s a lot lighter than cast rock and much more cost effective to install.
