The Neoclassical main building overlooks Ulvsund and the Queen Alexandrine Bridge, with the island of Møn in the background.

Born in Stavreby at Jungshoved, Johansen was the son of a poor immigrant farmer from Poland (Johan Klabovsky).

He sold it to Michael Conrad Fabritius de Tengnagel, the occupant of the Iselinske Fideikommis,[3] who refurbished the buildings.

His widow, Nana Felicia Augusta Fabritius de Tengnagel, née Bilsted, stayed on the estate after his death.

In 1870, Scavenius' son sold it to the wealthy merchant Ole Berendt Suhr, who had already purchased the Petersgaard forests from the state two years earlier.

She therefore endowed Petersgaard to her relative Jens Juel, a grandson of her sister Sophie Clara Anna Suhr and Frederik Vilhelm Treschow [da] of Krabbesholm.

The Neoclassical main building consists of two storeys above a raised cellar and has a hipped tile roof with two chimneys.
