Famed town planners and architects Andres Duany and Elizabeth Plater-Zyberk designed Rosemary Beach with a respect for the natural landscape along 30-A. This traditional town is also built with a high regard for the neighborly village atmosphere of 30-A's original neighborhoods such as Grayton Beach, where dune walkovers and alleyways bring vacationers and year-round residents together.

Rosemary Beach features a West Indies-style architecture that is well suited to the rustic luxury of the area, and this sense of style is reflected in each individual vacation rental as well as in the cuisine, arts and shopping of this destination.
