Architectural Elements
Quoin
Quoins are decorative blocks or projecting masonry units placed at the exterior corners of buildings, creating visual emphasis and the appearance of structural reinforcement. Historically, quoins were large cornerstones that actually strengthened rubble wall construction; today they serve primarily as decorative elements suggesting solidity and classical architectural heritage.
In interior applications, quoin-like details can appear at room corners, fireplace surrounds, and architectural niches—applied blocks or painted representations that reference the exterior tradition. Interior quoins add textural interest and classical vocabulary to otherwise plain surfaces, suggesting masonry construction even in wood-framed homes.

Placement & Usage Tips
Quoins work at room corners, fireplace surrounds, and architectural niche edges. Alternating block sizes (stacked pattern) is most traditional. Scale appropriately to the feature—larger for fireplaces, smaller for niches.
💡 Pro Tip
Create interior quoin effects economically with MDF blocks or even painted trompe l'oeil representations. For fireplace surrounds, precast stone quoins provide authentic appearance without custom masonry work.
