The exposed wood in this 7,500-square-foot library addition takes many patrons in this urban setting by surprise. When the City decided to expand the Stapleton Branch of The New York Public Library, architects chose to honor the wood-lined Beaux Arts interior of the original Carnegie facility by designing a new wood structure that imparts richness, scale and a sense of craft. Glulam was chosen for the structural beams, roof decking and posts because of its constructability, which ensured precision and consistency in material and workmanship and streamlined erection. Wood’s inherent design flexibility permitted the economical introduction of multiple framed roof openings, which provide natural daylight. Variegated surfaces of the exposed wood ceiling help diffuse and deflect sound, taming acoustics in the library space. The use of wood imparts a warm yet dignified atmosphere to a unique, modern library, giving the interior a glow not often seen in modern institutional buildings.
