The Flynn Company is pleased to present The Cast Iron Building; a unique office setting that combines 21st century efficiency and convenience with a 19th century treasure. The front elevation cast iron is emblematic of progressive commercial building techniques from the late 19th century and it is now the largest contiguous cast iron elevation remaining in the Philadelphia region. The building’s historical character conceals recently upgraded state-of-the-art lighting, heating and cooling systems, delivering one of the lowest energy costs to occupy factors in the city.
