The grounds are truly exceptional--award-winning gardens that have been meticulously maintained by the same master gardener's family for over three decades.

A property of this scale, provenance, and potential--complete with garage, guest house, and extraordinary gardens--is an increasingly rare offering South of Broad. 54 King Street presents a unique opportunity to honor its rich history while creating a bespoke residence tailored to modern living.
