A barn door is a distinctive design style known for its rustic charm and practical functionality. Inspired by traditional farm doors, it typically features a simple, sturdy construction with visible wood grain, diagonal or cross-bracing details, and a weathered or natural finish that enhances its rustic appeal. Usually installed as a sliding door using exposed metal hardware, a barn door adds character and warmth to both modern and traditional interiors, while also serving as a space-saving solution for rooms with limited swing clearance.
