This stunning c. 1785 four-story masonry home has been carefully preserved, exhibiting significant historical integrity. It has undergone a meticulous renovation, elegantly updated to accommodate modern living and entertaining. Book-ended by Rainbow Row and High Battery, the Jonathan Simpson House was built within the original walled city by a wealthy merchant. Twelve-foot ceilings and grand rooms allow the house to be filled with light. The pine floors run the full extent of the house (28). Much of the original molding, cypress paneling, doors, and interior shutters remain. The current owners created a hyphen to connect the original home and kitchen house under the direction of renowned Charleston architects Dufford Young, with construction by Artis, winning a 2019 Carolopolis Award. The project allowed for a new side garden design by Sheila Wertimer. The gourmet kitchen features a butlers pantry, mudroom, and floor-to-ceiling steel doors overlooking the side garden. The former kitchen house now features a spacious second-floor guest suite or office and a large secondary living room flanked by original fireplaces, as well as access to the screened porch overlooking the magnificent backyard that encompasses nearly a quarter of an acre of peace and tranquility. Plans were created for a 10 x 30 swimming pool and have been approved by the city. The original staircase remains, rising eloquently for all four flights, one of the tallest in the city. The second floor of the home has a 21×25 drawing room with five floor-to-ceiling windows. Across the hall, a primary suite with a fireplace and a private porch overlooking historic rooftops and palmetto trees. The third floor includes two spacious bedrooms, both with en-suite bathrooms, as well as a laundry room. The front bedroom offers clear views of Charleston Harbor. The back bedroom offers a private porch thats perched in the palmetto trees. The fourth floor is laid out as a two-room guest suite with a full bathroom and a living room, incredible historic and water views from every window. Of significant architectural interest is the cantilevered marble balcony, which projects from the second floor and is the only one in Charleston constructed in this manner. The elliptical fan light and the use of tall, glazed windows typify the work of the Adam period. Also of notable distinction is the detailed woodwork and roping around the door frame, which makes this one of the more attractive entrances in historic Charleston. The home retains architectural features of the late Georgian period, also embracing the ornamentation that more closely resembles the Adam style or the Federal period of architectural development.
