St. John's occupies a triangular lot on the north side of Sanbornville village, bounded by High Street, Wakefield Road (
New Hampshire Route 153), and St. John Street. The church is located near the center of the parcel, and is oriented facing west toward High Street; to its south is the rectory, also facing High Street, and the parish hall is on the east side of the lot, oriented at an angle to the other two buildings in order to properly face Wakefield Street. The church is a handsome example of Gothic Revival architecture, designed by
Charles C. Haight. It is one of the architect's earlier works, and is clearly based in part on a design for country churches published by
Richard Upjohn in his 1852 book
Rural Architecture, but with more elaborate flourishes. It has an asymmetrical cruciform plan with a tower projecting to the right of its street-facing facade. The rectory was added in 1881, and the parish hall in 1894; both are vernacular expressions of late Victorian architecture. ==See also==
