Built in 1924, Charleston’s Francis Marion Hotel is a twelve-story architectural landmark undergoing extensive restoration. Named after a Revolutionary War hero, the structure features cast-in-place concrete columns, poured concrete decks, and hollow terra-cotta blocks with brick filling. The building comprises two connected structures at King and Calhoun Streets, with the King Street side featuring commercial elements and a flat roof, while the Calhoun Street side has residential-style architecture with a gable roof.

In 2020, a comprehensive restoration began to address water intrusion, deterioration, and wear. The assessment required historical research, material analysis, and compliance with modern codes and regulations. At over 180 feet tall, inspection necessitated drone technology and rain-event observations.

The restoration revealed extensive damage: corroded window lintels, rotted wood windows, and unsound masonry caused by decades of water infiltration. The most challenging phase involved a 1930s cantilevered stairwell. With no original drawings, the team conducted destructive testing while working 150-180 feet above ground on complex scaffolding. The restoration included replacing over 20 linear feet of corroded rebar with stainless steel, installing 500 helical ties, and pouring self-consolidating concrete, successfully restoring the 12th floor to service.
