The two-story stone structure at Philipsburg Manor Upper Mills was constructed by Frederick Philipse in c.1680 and its size was doubled around 1720. During the 17th and 18th centuries, the building was likely used as an administrative office and site manager’s residence for the northern portion of the Manor of Philipsburg. Following the American Revolution, the manor was dissolved, and the property passes through the hands of several owners who altered and enlarged the house. Saved from demolition in the 1930s, the house was extensively remodeled during separate restoration campaigns: first in the early 1940s and again in the mid-1960s in attempts to return the building to its 18th century appearance. The building is a National Historic Landmark and is listed in the National Register of Historic Places.

The project consisted of two parts. First was a the preparation of a report that included archival documentation research, a comprehensive analysis of existing architectural features, and a conditions assessment to serve as the basis of comprehensive recommendations for appropriate treatment of architectural features installed in the 1960s. Subsequently, architectural and engineering documents were prepared for construction work that included: stone masonry repairs; replacement of solid oak window frames and casement window sash; replacement of wood siding; replacement of wood shingle roofing and flashings, plaster repairs; interior and exterior painting; complete replacement of electrical power and lighting systems; installation of code compliant smoke and fire detection and alarm systems; installation of a light sensitive LED accent lighting system at the interior; and, site work.

Project services were performed and directed by Robert A. Petito Jr., AIA, Associate with Jacobs/Wyper, while formerly serving as Principal and Project Manager with John G. Waite Associates, Architects, PLLC.
