There are also areas of former hard-paved surfaces, kerbing and guttering along the driveway loop. Particularly notable are the four remaining, handsome stone gate posts at the northern entry on Katoomba Street. The site and foundations of a fifth post (removed from the drive in the 1970s but with fabric still present within the grounds) may survive archaeologically. The driveway was realigned in 1912, and archaeological evidence relevant to that alteration may also be present.
