[1][4] As of December 2020,[update] the house is occupied by the Oldfield, Greaves, D'Agostino, Billo & Nowak law firm.

[4] Abraham Erb, the original architect of the house, came to the settlement that would become Waterloo from Lancaster County, Pennsylvania in 1806,[1][2] settling on Lots 14 and 15 of the German Company Tract.

[1][2] Erb chose the location because of its access to the road and because it sat on a hill, making the house slightly elevated from the surrounding land.

[2] He also owned the Waterloo Chronicle newspaper, was one of the founders of Dominion Life Assurance Company (later acquired by Manulife) and one of their first vice presidents, and served as Waterloo's postmaster for 42 years from 1862 until his death in 1904.

[1] The house has Georgian six-over-six windows, as well as a Regency façade with two wings, Treillage, a Gothic bargeboard, and Doric columns.
