Architectural Elements
Box Beam
Box beams are hollow decorative ceiling structures that mimic the appearance of solid structural timber beams without the weight or cost. Constructed from boards forming a three-sided rectangular channel mounted to the ceiling, box beams add architectural character and the warmth of wood to any space.
These versatile elements create visual interest in rooms with standard ceiling heights and can make oversized rooms feel more intimate by lowering the perceived ceiling plane. Box beams work in various arrangements—parallel runs, grids, or single accent beams—and accept stains, paints, or distressed finishes to suit different design styles from rustic farmhouse to refined traditional.

Placement & Usage Tips
Space parallel beams proportionally to room dimensions—typically 4-6 feet apart. Beam depth should relate to ceiling height; 6-8 inch depth works for standard 8-9 foot ceilings. Run beams perpendicular to the longest wall to visually widen narrow rooms.
💡 Pro Tip
Build box beams from 1x lumber for lighter weight and easier installation. Use pocket screws and construction adhesive for strong, invisible joints. Scribe bottom edges to ceiling irregularities before finishing for seamless appearance.
