Strandgade 30 is one of the oldest townhouses situated on Strandgade in the Christianshavn district of central Copenhagen, Denmark. The three-winged building from 1635 is via an adjoining lower building from the 20th century and a three-storey warehouse connected to a two-storey building at Wildersgade 43 on the other side of the block. The property was from 1680 until at least the 1860s owned by brewers whose brewery was located in the yard. The painter Wilhelm Hammershøi resided in the apartment on the first floor from 1899 to 1909. Some 60 of the 142 paintings from this period of his life, including some of his most iconic works, are interior paintings from the apartment. Other notable former residents include the ship-owner, merchant and slave trader Jens Lind. A doorway in a brick wall connects the narrow, central courtyard to that of Strandgade 28. Strandgade 30 and Strandgade 28 were owned by the same owners from 1910. They were jointly listed in the Danish registry of protected buildings and places in 1918. The building at Wildersgade 43 and the adjacent warehouse in the courtyard are also part of the heritage listing.
