De Lange created a large number of works of various types including civil and military buildings, mansions, country houses, warehouses, factories, churches and parks. The Dutch Baroque influence in his early work can, for example, be seen in the premises he built for Ziegler, the pastry cook, at Nybrogade 12 (1732). While initially he appears to have been struck by
Ewert Janssen's earlier work, he soon seems to have been influenced by
Elias Häusser and
Lauritz de Thurah. Like
Krieger, he participated strongly in creating fine bourgeois dwellings in Copenhagen, especially the gabled houses on
Købmagergade. His most notable achievements include the Headquarters of the
Asiatic Company in
Christianshavn (1739), the
Masting Crane on
Holmen (1750) and Stephen Hansen's Mansion in Helsingør (1763). He also adapted
Glorup Manor on
Funen to the Baroque style adding a magnificent mansard roof (1744). For almost 30 years, de Lange was the leading master builder at the
Holmen Naval Station. Among other things, he constructed 24
Nyboder two-storey houses from 1754 to 1756. De Lange is remembered above all for his fine, simple buildings in the classical Rococo style. A good example is
Damsholte Church on the island of
Møn, the only Rococo village church in Denmark. ==Personal life==
