An eye-catching expansion does double duty at the Colorado School of Mines in Golden, Colo: The three-level masonry addition updates the 50-year-old Hill Hall while blending with adjacent historic buildings more than twice that age. Rising above the original 67,000-square-foot, L-shaped facility, the $16 million, 35,000-square-foot addition creates a multi-faceted effect.

By combining red sandstone with gray, dark red, and beige brick, this imposing new presence at the northeast corner of the main quadrangle draws from the palette of the campus's older buildings. The external design uses ornamental concrete to reflect the internal program. Precast concrete lintels depict elements representing the evolution of knowledge of metallurgy.
