Original Brewery Building
Originally a four-storey tower, with symmetrical two-storey wings running to the east and west.
The tower was roofed with galvanised iron with a central ventilating lantern running north-south with four accompanying ventilation dormers.
Each floor had two windows on the northern face, with two on the east and west faces on the fourth floor.
A verandah ran across the front of the tower, part of which was enclosed to form an office in 1878.
The wings to the east and west terminated in brick gables that projected above the roof line.

In around 1880 the tower was enlarged and large openings created for vehicle access.
Additional dormer windows and ventilation lantern was added.
In 1911 the west wing was altered to allow the creation of a Gyle Room with three gyle tanks to be added to the first floor.
In 1912 the east wing was altered internally by raising the ground floor to match the later additions and a parapet was added to the northern wall.
Two more Gyle tanks in the western wing required supportive alterations.
In c.1920 the dormers and ventilation lantern was removed from the roof of the tower.
Pitt and Merewether, designed extensive internal modifications to convert the buildings into a storage distribution depot in 1938, including drastic alterations to the northern ground floor to allow for new awnings and a loading dock.

Wood Street Brewery Building
A two-story building, with lofts, constructed in two stages between 1878–1885.
The ground floor was concrete with a timber first floor, clad in brick with a galvanised iron roof.
The Wood Street facade features two projecting gables and the roof profile creates an "M" shape, with central box gutter and fascia gutters.
The 1878 section was built by George Yeomans as a malting room with overhead storage.
In 1897 the ground floor was converted to refrigeration storage through the addition of cork insulation and loading access was created from the Hunter Street courtyard.
Major internal alterations were undertaken in 1911, designed by E.G. Castleden, as a response to innovations in brewing technology.
New skimming rooms were created on a raised floor in the centre of the 1878 building and an office and laboratory were created on the first floor.
Prior to 1938 a cart dock was created on the eastern wall to load from the ground floor cellars.
In 1938, when the new garage was built, the openings in the eastern wall were bricked up.

A 1911 illustration by E.G. Castleden indicates a room was attached to the south-east corner, also a shed, a Boiler Room, Chimney Stack and Engine Room to the south.
These were demolished in 1938, along with workshops, harness room, bottle washing shed and earth closets along what was the eastern boundary.

Condenser Tower
No documentary evidence exists regarding the construction of the Condenser Tower, which first appears on a Department of Lands Map in 1896, although it is believed to have been constructed in 1878.
Castleden's drawing of 1911 describes the structure's purpose as bottle washing, however, it has a shape traditionally associated with malting houses.
The brick tower is square and topped with a pyramidal timber roof and ventilation lantern.
Between 1911 and 1938 Castleden converted the tower from a malting house into a condenser tower.
The pyramidal roof was removed and the masonry extended to three storeys.
A refrigeration plant was located on the ground floor, with brine tanks on the first and second floors, supported by concreted and steel-framed barrel-vaults.

Bottle Store and Office
A two-storey construction, originally housing bottling equipment, with a single story section on Hunter Street for the office and reception area.
The single storey section has a triangular pediment over an entry portico, with rendered pilasters to add continuity to the Hunter Street facade.
The two storey section echoes the office, with the addition of a curved gable and a bullseye window common to the Federation style of the early 20th century.

The eastern facade was modified in around 1914, with the addition of a bottling ho
