One signature piece of the property is the cartouche, custom carved in Texas by a world renowned carver using Leuders limestone. The cartouche is centered on the parapet at the portico of the Residence. Historically appropriate, it reflects perfectly the strength of the portico profile with its strong vertical lines yet tempered by a perfect overlay of playful carved filigree.

The filigree is bordered by scrolls and capped with the state flower of Georgia, a Cherokee Rose. The field of the filigree has a fleur deli and three spheres representing the alchemic elements (Mercury, Sulfur, and Salt) which were considered to be the three constituents of the Philosopher's Stone, a mythical substance believed to be capable of turning Lead into Gold.

The border scrolls, if mentally unrolled, would reveal the chapters of evolution for the Little Hawkins Island development.
