PURL (Phoenix Urban Research Laboratory) (in the Security Building)

The Security Building is significant for its association with Dwight B. Heard and as a good example of Second Renaissance Revival architecture. The building was constructed for the Security Improvement Company, a local Phoenix business. Dwight B. Heard, prominent Phoenix realtor and cattleman, was President of the Security Improvement Company when the building was constructed. Heard was one of the city’s most powerful and influential men from 1897 until his death in 1929.

The modified Italian Renaissance Revival features include an arcaded gallery at the top story, a corner tower, hand-molded brick walls, concrete quoins and a recessed/offset pediment. Interior character-defining features include marble floors and wall coverings, brass elevator doors, painted designed ceilings, original light fixtures and letter drops. The building was designed by Curlett and Beelman, and constructed by Edwards, Wildley & Dixon contractors, both regionally recognized architects and builders, respectively. The ASU Phoenix Urban Research Laboratory is located on the 8th and 9th floors of the building. The building is owned by the City of Phoenix.
