Swedish architect, son of the architect Göran Josuae Adelcrantz (1668–1739), he was a pupil of Carl Gustav Tessin (see Tessin, Nicodemus the Younger). Appointed Supervisor of Court Buildings in Stockholm (1741), he remodelled the riding-master's quarters at Ulriksdal as a theatre in the Rococo style (1753). Drawing on Chambers's Designs for Chinese Buildings (1757), he created the charming Chinoiserie pavilion at Drottningholm (1763–9), and designed two more theatres (Drottningholm (1764–6) and the Royal Opera in Stockholm (1777–82). In 1768–74 he built the Adolf-Fredrik Church in Stockholm, much influenced by French Classicism, and remodelled other Stockholm buildings in a Neo-Classical style.
