The Supreme Court was based on the beletage from the fire of the second Christiansborg Palace in 1884 until the completion of its current building in 1919.

Then followed the two lots at the corners of the axially symmetric street Frederiksgade that marked the entrance to Amalienborg from Norgesgade (now Bredgade).

In return for 30 years of freedom from property taxes, the two privy councilors Frederik Ludvig von Dehn and Count Johann Hartwig Ernst von Bernstorff committed themselves to building the two identical town mansions that were called for in Eigtved's masterplan.

Bernstorff and Dehn commissioned the architect Johann Gottfried Rosenberg to design and construct the two buildings.

Andreas Petrus Bernstorff resided in the building with his wife Augusta Lowisa (née Stolberg), their six children (aged six to 20) and the hovmester Ferdinant Kock.

[6] Johan Friderick Baumgarten, an inspector at the Class Lottery, resided in the building with his wife Dorothea Friderica, their daughter Ide Hedevig, one maid and one female cook.

Prince Carl (later Haakon VII of Norway) resided on the ground floor following his wedding marriage to Princess Maud in 1897.

The building was designed in the Rococo style by J. G. Rosenberg but approved by the Court master builder Nicolai Eigtved, who was responsible for the overall supervision of the new town district of Frederikstad.

The principal facade towards Bredgade consists of three three-storey pavilions connected to each other by lower two-storey sections.

The piano nobile, the main floor, has tall round-arched windows with rich decorations above, vases and cartouches on the ceilings.
