Frank Culotta Contractor was selected to complete the $1.6 million restoration of the Duggan Building, an historic preservation structure located in the Main Street Historic District of downtown Baton Rouge.

The Duggan Building, situated in the Main Street historic district of the city, forms part of an intact group of architecturally significant commercial buildings constructed between 1830 and 1935. It shares a common history with the majority of buildings in the district and is a typical example of the size, scale, ornamentation and materials popular at the time of construction.

The name "Duggan Building" appears in the plaster at the top of the structure and also on the building across the street.
The Duggan Building is a three-story, rectangular structure with a mezzanine at the rear of the first story. The existing flat front elevation features six large openings that have been modified to form false arches and is in-filled with steel windows on the third floor, wood windows and frames and wood doors for the lower openings.

Although the existing front elevation was altered in the late 1980s, the original clay tile mansard roof remains a feature on the front elevation, along with intricate detailed patterns in the plaster. These items remaining on the front elevation are from the building's original construction.

The building interior was completely remodeled in the late 1980s as well. At that time, it was subdivided into 100- to 200-sq.-ft. offices with a 4-ft. corridor wrapping an interior core of offices. The original interior structure of the building is still intact with 1-ft.-sq. vertical wood columns, 2 in. by 12-in. actual size clear-heart, longleaf pine wood framing at the joists, steel I-beam supports and longleaf pine wood flooring.

The Duggan Building has been the home of a Baton Rouge law firm since its recent completion.
