- Caldwell-Hampton-Boylston House


Carriage House Preservation Study

In 2018, GMK was retained by the South Carolina Department of Administration to complete a formal “preservation study” related to main Caldwell-Hampton-Boylston House – Carriage House/Stable structure. This project included architectural and engineering analysis and narratives of the scope of work to determine an opinion of construction cost for necessary future renovations. GMK prepared plans and diagrams to the extent necessary to describe the scope of work with the intent of preserving the existing structure through maintenance and repair of existing historic materials and retention of a property’s form as it has evolved over time. GMK then prepared the architectural and engineering designs to complete the recommendations laid out in the study in coordination with SHPO guidance.

The Boylston Carriage House is a supplementary structure to the Caldwell-Hampton-Boylston House – a historic residence located on the Governor’s Mansion grounds. The historic residence and carriage house are currently owned by the State, and the home is utilized by the Governor’s Mansion and the Welcome Center’s staffs. The carriage house is currently used for storage and various needs pertaining to the Governor’s Mansion grounds.

GMK’s completed preservation study established a comprehensive set of improvement recommendations for the Carriage House to preserve the building’s structure and overall historic nature and aesthetics. These recommendations addressed architectural (windows, brick, roofing, exterior wood doors and finishes, gutters and downspouts, and the upstairs apartment), HVAC/mechanical, plumbing, electrical, and structural (roof structure, roof deflection, wall framing, and foundation), and site civil (landscape gates and posts and overhead foliage) issues.

GMK further began basic architectural and engineering services for design of the preservation measures planned for the building. However, control of the project was subsequently turned over to the South Carolina Department of Parks, Recreation & Tourism as part of the larger effort to complete improvements for multiple buildings that make up the North Mansion Complex (i.e., “The Venues at Arsenal Hill” project).
