 After numerous proposals the sand hills rear and north of the fort were removed in 1882 , improving the fort 's land defence and allowing the 64 @-@ pounder guns to sweep the Semaphore jetty . This now levelled area was used as a bivouac and exercise area for the colony 's volunteer troops . A stable , office , shed and gunner 's store were also erected north of the fort . The gunner 's shed was damaged by fire in 1895 and replaced further eastward . These buildings did not survive into the 21st century .
