 The site was expanded to the west in the mid 1900s which involved the removal of Wescombe Street and the historic cottages that lined it in order to make a 3rd gasometer and later an LPG cylinder yard when the site was taken over by Boral and eventually Origin Energy.In 2007 the site was sold and the 3 gasometers were largely dismantled.The cylinder yard has now been built over by the new Centrelink building and car park with additional developments planned to take place in the future.
