Block F is a long, single storey, brick veneer building with a low-pitched gable roof.
In 2016 it is used as a student services building and comprises: a central entrance lobby and waiting area; two large and one small offices / meeting rooms to the southwest (former open-plan library), with a passageway along the northwest side; and two small office / meeting rooms (former Principal's Office), and a store room and kitchenette (part of former waiting room and an original store room), to the northeast.

The main entrance from Nicholson Street is indicated by a flat-roofed metal-framed canopy and a stencilled, poly-chrome painted concrete slab; it has stained timber-framed wired-glass doors, with sidelights.
A ground floor covered walkway connects the western side of the lobby with Block D to the west.

The southwest section has banks of timber-framed awning windows on the southeast side (with fanlights) and along the passageway (clad above externally in profiled metal).
Some of the timber-framed awning windows on the northeast wall have been replaced with metal-framed sliding windows.

The interior walls and ceilings are predominantly flat-sheeted, with rounded cover strips.
The lobby interior combines flat-sheeted and face brick walls.
The wall between the two large southwest offices (1972) is clad in stained timber-veneer.
The doors are a combination of painted, stained timber-veneer and half-glazed.
