The building is a Georgian style and is largely unaltered since its original construction.

[1] The parcel of land on which the Bonnett House resides can be traced back to 1699, with the first known owner being Jean Chrysostome Loppinot, attorney-general of Acadia.

[2] At least two other dwellings were constructed on the land between 1699 and 1773, these structures being destroyed by fire in 1708 and, again, in 1710.

[1][2] By 1773, Pardon Sanders an artificer at Fort Anne, built the current house.

[1] In 1783, Sanders disposed of the property to Frederic Davoue, a Loyalist from New York, who quickly sold the house to merchant David Bonnett.
