Building structures

摘要

A method of making a domed building structure includes locating a ring beam having a radially inwardly extending circumferential locating formation on top of an upwardly extending building structure. The method also includes locating a plurality of prefabricated dome units adjacent one another on the locating formation of the ring beam, in a first annular course. Further annular courses are then located in position, thereby to form a domed top.
