The Niels Brock House is a historic property located at Strandgade 36 in the Christianshavn neighbourhood of Copenhagen, Denmark.

Other notable former residents include the historian Peter Vilhelm Jacobsen [da] (1799–1848) and the businessman Christian August Broberg.

He resided in the building with his housekeeper M. C. Adolph, his bookkeeper Jens Perch, two clerks, a female cook, a maid, a coachman and a caretaker.

His father, Hans Nicolai Sommerfeldt, was a teacher at Randers Latin School and Niels Brock was his godfather.

He lived there with his wife, their four children, two housekeepers (husjomfruer), a female cook, a maid, a male servant and a caretaker.

Carl August Broberg still resided on the first floor with his wife Camilla Broberg, their three children (aged five to eight), his two unmarried sisters Anna and Marie (aged 36 and 43), a nanny, a nurse, two female cooks, one male servant and one maid.

Sthyr & Kjær sold the property to J. J. Carøe, a leading importer of tea and spices led by Henri Odewahn and K. Gram.
