The present building on the site was constructed in 1740–41 by Philip de Lange for affluent Jacob Barchmann.

[2] In 1795, Hansteen sold the corner mansion to Supreme Court lawyer Carl Henrik Wilster.

He was originally from Saint Croix where his father Henry Ryan was the owner of the sugar plantation Mary's Fancy.

Ryan had moved to Copenhagen in 1780 where he initially worked for Dunzfeld, Meyer & Co and later started his own trading firm.

On 4 December 1809, Hage sold the mansion to the Jewish merchant Jacob Salomon Meyer (1783–1845).

In 1811 the Barchmann Mansion was acquired by the industrious landowner Jacob Brønnum Scavenius.

He had made a fortune in Danish India and on his return to Denmark acquired Ghorslev Manor on Stevns.

Henriette Sofie Margrethe Elisabeth Treschaw (née comtesse Rantzau), her daughter-in-law, married to her son Carl Adolph Rothe Treschow (1839–1924), resided in the building with her three children (aged nine to 14), two tutors (one male and one female) and one chamber maid.

In 1926, the house was divided into two separate properties when Borup Folk High School moved into Frederiksholms Kanal 24.

The facade to the right of the portal covers the stables to obtain the symmetry required by the Baroque style.

[1] Since 2008 the building has been owned by Bendt Wedell, the second largest private land owner in Denmark, whose other holdings include Wedellsborg and Frijsenborg in Jutland.
