Quoin
A quoin is a decorative and structural feature used in building construction, particularly in masonry work. It refers to the corner blocks or bricks that are different from the rest of the wall, either in size, color, or how they're arranged. Think of them as special corner pieces that make buildings look more attractive while also making the corners stronger. You might see them on historical buildings, modern homes, or commercial structures where architects want to add visual interest to the corners. When someone mentions quoins in their resume, they're typically referring to their experience with specialized masonry techniques and architectural detailing.
