Hamilton commissioned architect John McComb Jr. to design a country home on Hamilton's 32-acre (0.13 km²) estate in upper Manhattan. The two-story frame Federal style house was completed in 1802, just two years before Hamilton's death during a duel with political rival Aaron Burr on July 11, 1804. The house was named "The Grange" after Hamilton's grandfather's estate in Scotland. (A grange was originally a place where food was grown for a monastery.) Hamilton's mother, Rachel Faucett Lavien, also lived there for a time and is buried at an estate named Grange on the island of St. Croix. The Grange was the only home ever owned by Hamilton and it remained in his family for 30 years after his death.
The Hamilton Heights neighborhood of Harlem derived its name from Hamilton and the Grange.
St. Lukes used the house for services and subsequently erected a Richardsonian Romanesque building on the site between 1892 and 1895, thus tightly enclosing the building between the church and an adjacent six-story apartment building and hiding many of its features.
The property was designated a National Historic Landmark on December 19, 1960 and Congress authorized the National Memorial on April 27, 1962. At the time it was determined that the claustrophobic Convent Avenue setting was inappropriate and that the country house should be viewed as freestanding building. However, the house was not relocated in 1962 because of overwhelming local opposition to moving it out of the neighborhood. The Grange was administratively listed on the National Register of Historic Places on October 15, 1966.
Work in St. Nicholas Park for tree removal and foundation construction began in February 2008. The actual move of the Grange began with elevation of the building in one piece over the loggia of St. Luke's Church and onto Convent Avenue. The Grange was placed on specially-built stilts that held the entire house approximately ten feet off the ground in the middle of Convent Avenue, between W. 145th and 142nd Street while traffic was routed around the house. The house completed its journey on June 7, 2008 by being rolled one block west on Convent Avenue and then one block south on 141st Street (down a 6% grade) to the new St. Nicholas Park location. The six-hour event was a popular neighborhood attraction covered extensively in the press.
Once the house is secured to its new foundation, the original porches will be rebuilt and the original main entrance doorway and main staircase within the entry foyer will be restored. Landscaping around the Grange's new home will include tree plantings, a stone wall and paths. The Grange will have security detail during the day and possible video monitoring during the evening hours.
