The Security Building, built in 1929, was designed in the Renaissance revival style and is listed on the National Register of Historic Places and the Phoenix Historic Property Register. At the time of its completion, it was the tallest building in Arizona and a symbol of technology, with a cupola that projected a beam of light visible for 30 miles.
But 85 years later, bringing the building into the 21st century meant overcoming limitations inherent to older buildings.
