A row of small houses along the canal were later turned into separate properties. The property now known as Nyhavn 8 was listed in the new cadastre of 1756 as No. 276 in St. Ann's East Quarter. Together with some of the adjacent houses it was used as residences for staff at the botanical gardens. which were then situated at the northern end of Amaliegade (cf. Amaliegade 45).

Nyhavn 12 was built circa 1770 for merchant and shipowner Andreas Bodenhoff.
