Designed by Alexander Dawson,[3] the New South Wales Government Architect at that time, both the lighthouse's flared base and the keeper's cottages combined terrace are unique architectural features for the period.

[5] Another report in 1912 stated that the station was in good condition, but criticised the low power of the light, and recommended withdrawing two of the keepers.

However, all of these recommendations were not acted upon until 1 July 1922,[8] when the apparatus was upgraded to a revolving Dalén light with an intensity of 20,000 cd,[2] and the manning reduced to two keepers.

[5] In 1960, the lighthouse was electrified and connected to the mains electricity through a submarine power cable, and a backup diesel generator was installed in the basement of the tower.

All logs, drawings and furniture were therefore burned as surplus by the Department of Transport's employees, and the buildings were set ready for demolition.

[9] There three lighthouse families living there were two month supply of food and barge called Bomb Snow in case they would cut off due to rough seas.

[9] In 1990,b following a 1989 failure of the submarine cable and problems with the diesel generator, the light was converted to solar power with battery storage.

[7] In 1992 the Australian Construction Services cleared the site and stabilised some of the building elements, and a security fence was installed.

[8] The walls of the tower are constructed of sandstone blocks, brought by ship as ballast from Sydney, dressed outside and inside, and painted white.

The roof was originally made of slate, replaced in 1901 with terracotta, with five chimneys along the ridge and a bay window and gables along the front.

[11] Several service structures used to be located behind the resident buildings, namely kitchen, privies and stores, and were destroyed in the 1991 fire, leaving only parts of the timber walls.

[5] A brick privy with a gabled roof clad in corrugated asbestos sheeting is located to the north of the cottage building.

[5] An above ground brick fuel bunker with a concrete roof and floor is located approximately 40 metres (130 ft) south of the lighthouse, on a rock outcrop.

[5] At the north of the island are the remains of a 19th-century wharf including concrete tracks, rock cutting and iron fixings (several brackets and stumps).

[3] On 2 April 1999, the lighthouse and adjacent structures were listed on the New South Wales State Heritage Register with the following statement of significance:[5] Point Stephens Lightstation and its setting are significant as one of a collection of lighthouses which combine the natural values of a coastal environment with the cultural values of a prominent landmark and isolated settlement.

The semi-detached terrace, now in a ruinous state, is among the most architecturally accomplished of the early detached residential housing type.

The light station retains a rare remnant of the original Wilkins & Co lantern and has the potential for archaeological study at both the lightstation and wharf precincts.
