The building is now semi-derelict as the roof has been removed. All of the ground floor offices are now used as storage areas. They have timber floors, painted brick walls (which were originally plastered) and a plaster ceiling with the original cornices intact. The stair hall to the eastern end was originally part of the offices but converted c.1914 to give access to the first floor. The stair is of timber construction with original boarded wall on the ground floor to the old storeroom. The open passage to the east of the stair is a concrete paved access way to the attached brick toilet block, which is reached by a steel stair. The offices on the first floor have timber floors, painted brick walls (which were originally plastered) and a plaster ceiling with the original cornices intact. Each of the rooms has an original fireplace. The eastern most room has been converted into a bath room with a tiled floor and shower bath. This large open area was formed in 1899 with a series of 16 tram tracks fanning out from two tracks at King Street. Now partly paved over there is evidence of much of the original tram tracks remaining particularly obvious on the northern boundary with the railway line. A boundary wall on Railway Lane is part of the 1918 railway institute building (now demolished) while the other boundary brick wall is an original retaining wall. The main sewer line connecting to the station travels in a north-south direction from the station platform across the site to Railway Lane. This is a slightly smaller yard leading off Angel Street which contains a later railway signal and communications building but now is virtually vacant. This area is accessed through chain wire gates from the street. It may contain the foundations of a number of buildings which were once on the site including the Mortuary Station, stables and Blacksmith's shop. It also was on the north frontage of the tram storage shed with amenities and the electrical stores. Design features including:   The former Newtown tram depot has state historical significance as it formed an integral part of the electrification of the NSW tramway system which commenced in 1899. Being the second of the tram depots built to service the new electric tram fleet the buildings, it represents the high level of commitment by the government to providing a mass electric transit system service for Sydney's suburbs at the start of the 20th century. The tram depot site and its buildings are representative of the typical electric tram depot layout constructed as part of the NSW tramway system. The large tram shed and the associated tram offices exemplify the common architectural style of the NSW tramway buildings built during and just after the time of Federation.
