Structure
The distinctive roof comprises sets of interlocking vaulted
‘shells’ set upon a vast terraced platform and surrounded
by terrace areas that function as pedestrian concourses.

14. Materials
 The roof shells

15. Materials
 spherical roof-shells ‘gave way for a very logical and
orderly geometry for the tile lids that were to cover the
entire surface of the shells'.

16. Materials
 The glass wall facing the harbour
 The glass wall that was built after Utzon left. Its feeling of
hanging from the shell.
