Ny Kongensgade 3 is an 18th-century property located in the small Frederiksholm Quarter of central Copenhagen, Denmark.

The property was the site of a six bays long one-storey building with a three-bay wall dormer.

On 9 December 1747, the property was sold by auction for 1,501 eigsdaler to royal building master Jacob Fortling.

The identity of the architect is not known but it is believed that it was designed by Philip de Lange who had also constructed Barchmann's first mansion at the site.

Their properties at the corner of Frederiksholms Kanal at Ny Kongensgade were subsequently sold by auction on 21 February 1788 to different buyers.

The property was in 1877 acquired by merchant Gunni Busck, owner of Scandinavian Preserved Butter company, who that same year also founded Københavns Mælkeforsyning.
