Security Building, Bank building in Downtown Miami, United States

The Security Building at 117 Northeast 1st Avenue is a 16-story, 225-foot tower completed in 1927 to Robert Greenfield's design. Its 50-foot frontage holds a temple-like three-story base with engaged pilasters, bronze spandrels with relief ornament, and the name incised in the entablature. Above, paired and triple windows run to floors 14 and 15, which a round arch unites beneath a copper mansard roof pierced by arched dormers and bull's-eye windows.

The structure was completed in 1927 for the Dade County Security Company and served as headquarters for multiple financial institutions. It played a key role in Miami's emerging financial industry during the early 20th century.

This building reflects Miami's transformation into a financial center during the 1920s, when numerous banks established their headquarters here. The architecture speaks to the prosperity and importance of the location for the expanding business world.

The building is a private office location, not a public attraction, so the interior is not open to casual visitors. It stands mid-block on NE 1st Avenue with a zero-foot setback, its entry doors opening straight onto the sidewalk, and the facade can be viewed from the street. The ground-floor bank vault now serves as a quiet room for members.

The building's 50-foot frontage on NE 1st Avenue left architect Robert Greenfield little width, so he gave the first three stories a temple-like base of engaged pilasters framing three bays. Bronze spandrels with relief ornament sit between floors, and the name "Security Building" is incised in the entablature. The copper-clad mansard roof, unusual for Miami of the period, ends in a row of antefixae.
