J.C. Raulston Arboretum Education & Visitors Center

Raleigh, NC

The Arboretum’s Visitor Center anchors ten acres of magnificent gardens that are home to one of the largest and most diverse collection of landscape plants in the Southeast. It is a teaching and research facility for NC State University. The Center’s main structure was a combination of poured-in-place concrete walls, floors and roofs and laminated wood roof trusses. The unique design feature was the green roof that was designed for 250 psf live load, consisting of a thick layer of soil for the plants that could become saturated.

Louis Cherry, formerly of Cherry Huffman, worked on this project. The firm is now known as RATIO Architects.
