The Industrial Hall on Narrandera Showground is an example of the Federation Free Classical style of architecture (a style which dates from c. 1890 to c. 1915) which is characterised by symmetry, classical proportions and absence of detail with a playful quality.

The Narrandera Showground Industrial Hall is a small, single-storey, octagonal, weatherboard building with a bell-curved, domed corrugated iron roof.
The building measures 11m to the top of the dome that was formerly surmounted by a metal, louvred ventilator that was topped with a mini dome and a flagpole (the ventilator, dome and flagpole are now missing).
The eaves are supported with curved timber brackets which are set above an external timber cornice.

The building's octagon is not equal sided, but is more in the nature of a square with splayed corners.

The fifteen-pane windows are mounted in the four shorter sides of the octagon, with sill heights 2.4 m from ground level to provide a larger area of uninterrupted internal wall space for display.
The windows have lintels 4.7 m high and multi-coloured glass in the upper window panes.

There are two doors, in the east and west longer walls.
The eastern door, which appears to be original, is solid timber and comprises two units that slide open on an overhead track.
The western door is a newer roller door.

The internal walls are of vertical weatherboards to approximately one metre and then horizontal boards to the wall plate, which is about 4.8 metres above the floor.
A series of primary and secondary curved laminated timber ribs support the roof and ceiling, which again is composed of horizontal purlins and vertical tongue and grooved boards.
The primary ribs meet at a decayed octagonal timber ring beam, which supported the former vent.
There is a spoke of steel cross-ties at top plate level.

A painted timber and glass display cabinet fitted to the eastern wall of the building is the surviving remnant of the cabinets constructed in 1956 that originally lined the walls with a freestanding central cabinet.
The missing cabinets were probably removed after 1996 due to white ant infestation.

The wooden planks on steel supports along the western wall of the Industrial Hall are not specific to this building but move between it and the Pioneer Hall on the showground.

Internally, the high walls, large high-set windows and the exposed ceiling structure of the domed roof create a remarkable, spacious and well-lit interior.

An information board within the building states: "Building constructed about 1902 - cost 367 pounds - built by Charles Bundock - the only building of this design still in service in Australia.
 Note there was another building of this design built in Innisfail Queensland which was burnt down some forty years ago.
Building is listed by the Heritage Council".

The building was painted in 1993.
Previously the roof was unpainted corrugated galvanised iron and the lead ridges were more pronounced.

Prior to the 1970s the building was undermined by rabbits and started to sink.
During the 1970s, extensive renovations were carried out.
The building was restumped and rests on cement bricks in the centre and pipes embedded in concrete around the sides.
It now stands about 20 cm above ground level, with wire mesh around the bottom.
Guttering and down pipes have been renewed.
Cross-braced ties have been placed externally on the four main sides.
