Why it's listed

Upsala is a two-and-one-half-story stone house on Germantown Avenue in Philadelphia, set back from the street behind a stone facade of fine ashlar. Its main section was built in 1798 for John Johnson, who had inherited the property in 1797, and the front part was completed by 1801. The central arched doorway is sheltered by a wooden portico with Doric columns, and the cornice and dormers are notably detailed. Inside, a central hall leads to the main stairs, and the principal rooms have fireplaces with Pennsylvania marble facings and carved mantels. The Johnson family kept the house until 1941, and it is said that the name Upsala honors the Swedish author Frederika Bremer. The house is regarded as one of the finest examples of Federal architecture in the city. It was later purchased by the Upsala Foundation in 1944 and has since served as a historical society's headquarters. Its location opposite the Chew House adds to its significance.

Significance in brief: The nomination argues that Upsala is one of the finest examples of Federal architecture, citing its ashlar facade, elaborate cornice and dormers, and interior woodwork and fireplaces with Pennsylvania marble facings. It also notes the house's association with the Johnson family, who owned it from 1797 until 1941, and its location opposite the Chew House.

What listing means for this property

National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved.
