Forge Hill

Why it's listed
Forge Hill is a two-and-a-half-story dressed fieldstone house with a five-bay front, built between 1798 and 1800 in what is now Wawa, Delaware County, Pennsylvania. It was the home of Joseph Thatcher, a coachmaker, and remained in his family's possession until 1882. Thatcher, his two oldest sons and a grandson ran a profitable tilt and blade mill and coachbuilding shop along nearby Chester Creek. The house passed to George Wood in 1900 and then to his daughter Dorothea in 1936, when it had deteriorated badly. She commissioned a restoration that returned the house to its original character. The work recovered much of the original interior woodwork, including the mantels, reeding, gougework and five fireplaces, and replaced the tin roof with wooden shingles. A missing staircase was rebuilt using original reeded spindles. The property is valued for its early preservation of a historic building.
Significance in brief: Forge Hill was the home of Joseph Thatcher, a Delaware County coachmaker, and his family operated a tilt and blade mill and coachbuilding shop along Chester Creek from it. The house is regarded as significant as an early example of preserving a historic building, since its 1936 restoration rescued much original interior woodwork and returned the structure to its original character.
