Kennedy Supplee Rehabilitation Scope

With funding from the Great American Outdoors Act (GAOA), the National Park Service plans to fully rehabilitate the Kennedy Supplee Mansion and the surrounding Port Kennedy area. The mansion itself will receive a full exterior and interior rehabilitation, including all new building systems. Due to the historic nature of the mansion and its surroundings, the character defining features of the building and surrounding landscape must be maintained. Within the mansion, the primary character defining features include the current floor plan and all plaster & woodwork. The associated carriage house will also be rehabilitated. Utilities will be upgraded as necessary. Driveways, parking lots and the surrounding landscape will also be improved.

Great American Outdoors Act (GAOA)

Supported by revenue from energy development, GAOA funding is providing up to $1.3 billion per year for five years to the National Park Service (NPS) to make significant enhancements in national parks to ensure their preservation and provide opportunities for recreation, education, and enjoyment for current and future visitors. Valley Forge is slated to receive $32.5 million to rehabilitate buildings for adaptive re-use leases and demolish obsolete structures throughout the park.

Recent Operating History

In 1986, Kennedy Supplee Associates LP (KSA) signed a 55-year lease with the National Park Service, restored the building, and operated it as the Kennedy Supplee Mansion Restaurant. Following the 1987 renovation by KSA, the restaurant operated with approximately 1,100 square feet of dining space located on the first and approximately 2,200 square feet of dining and bar space on the second floor. The third floor was largely given over to HVAC equipment, but it also contained an office and liquor cage. Sections of the basement were used for cold storage and dry storage. See foor plans below. The company entered Chapter 11 bankruptcy in 2005. The mansion has been vacant since 2006.
