 The rear portion of the current building includes a massive chimney and was perhaps a small kitchen house behind Dr. Garden's house.In the mid-1990s, the rear portion of the building (sometimes referred to as 98 1/2 Broad Street) was in danger of being demolished to make way for an annex to the Charleston County Courthouse.The bulk of the current building was apparently built by Dr. Henry Frost in about 1835 and used as an office.
