Blackbird Fabrication is a Coatesville, Pennsylvania architectural metalwork studio that designs, fabricates and installs custom metal features for commercial and residential spaces. Founded by industrial designer Adam Sayres, the studio combines computer-aided design with traditional metal craft, handling projects from restoration and modification to complex turnkey staircases. Its work includes a four-floor, 60,000-pound stair assembled inside Microsoft’s New York City headquarters and a curved cantilevered stair made to match an existing Chester Springs home.
