Architectural Elements
Spandrel
A spandrel is the roughly triangular surface between the curve of an arch and the rectangular frame surrounding it, or the space between two adjacent arches. This architectural zone often receives decorative treatment—carved relief, painted embellishment, or medallion applications—transforming otherwise negative space into ornamental opportunity.
In interior design, spandrels appear above arched doorways, in arcaded hallways, and as decorative panels in rooms with arched features. The spandrel area offers a perfect location for applied ornamentation, painted decoration, or architectural medallions. Recognizing and addressing spandrels elevates arch treatments from simple curves to complete architectural compositions.

Placement & Usage Tips
Spandrel decoration should complement arch style—elaborate for ornate arches, restrained for simple curves. For multiple arches, keep spandrel treatment consistent. Consider lighting to highlight relief details.
💡 Pro Tip
Stock architectural medallions sized for spandrel areas can transform plain arched openings into distinguished architectural features. Center half-medallions in each spandrel for symmetrical ornament.
