In the 1780s the building now known as the Moltke Mansion after a later owner was acquired by merchants and ship-owners Frédéric de Coninck and Niels Reiersen.

Reiersen withdrew from the partnership when he succeeded his father as the proprietor of the Royal Silk Manufactory in Bredgade.

In 1794, he sold it to queen dowager Juliana Maria, who had been left homeless by the fire of Christiansborg Palace, but kept a piece of the garden towards Store Kongensgade.

The design has traditionally been attributed to Joseph-Jacques Ramée by Danish sources but this has been questioned by French, German and American researchers.

Louis de Coninck was in 1814 granted permission to go on a three-year trade expedition to Lisbon and the Mediterranean Sea on board the brig Marie.

He therefore chose to sell the house in Store Kongensgade to fellow naval officer Christoph Johan Friderich Hedemann (1786-1826).

The ground floor apartment to the right was occupied by naval captain lieutenant Paul Severin Kierulf (1793-1842) and his Norwegian-born wife Marie (née Mørch, 1898–1867), their 8-year-old foster daughter Clara Perkins and two maids.

The apartment on the first floor to the right was occupied by the unmarried businessman (grosserer) James Gordo (aged 52), 15-year-old Anders Bentzen and a maid.

The ground floor apartment to the left was in 1855 occupied by politician Carl Frederik Simony (1806-1872), his wife Anne Sophie Faber, and their eight children.
