It is part of the prestigious development which occurred in this period due to the wealth which Mount Morgan Gold brought to Rockhampton.

[1] Morgan's house was originally a four-roomed structure (two upstairs and two downstairs) with an open encircling verandah and a central hall containing a cedar staircase.

[1] In 1947 the property was purchased by William James Hinton who had a carrying business and used a portion of the ground floor as a warehouse.

[1] In 1962 the mercantile company John Headrick & Co purchased Avonleigh for the purpose of using the vacant land at the rear as a parking space.

The City Council required the company to construct two sets of stairs at the back of the building so each upstairs unit had a fire escape.

The verandah has cast iron columns, brackets, valance and balustrade, with pedestals and frieze to the ground floor.

The southern return has been enclosed at ground floor level with a dowelled timber gate and vertically jointed boarding.

[1] The building has two rendered masonry chimney stacks, and the rear of the structure has a first floor verandah which has been enclosed with fibrous cement sheeting and casement and glass louvre windows.

The ground floor has a lean-to addition at the northern end with fibrous cement wall sheeting and a corrugated iron skillion roof.

The ground floor northern professional suite has decorative plaster ceilings and cornices, with central panels depicting cherubs located in the principal rooms.

The skylight has been sheeted over externally, and the arch has moulded imposts and a central shield depicting an arm holding a sword.

A large room is located adjacent to the reception, with French doors with arched fanlight and sidelights of coloured glass.

The entrance has coloured glass fanlight and sidelights, and an arch with Corinthian order imposts divides the space.

This area originally housed a cedar staircase, the location of which is evidenced by infill to the boarded timber ceiling.

[1] The first floor northern flat has decorative plaster ceilings and cornices, with central panels depicting cherubs located in the principal rooms.

The southern flat has two large rooms either side of a central entrance hallway accessed via a timber panelled door, with enclosed verandahs at the rear and to the south.

Avonleigh forms part of the historic Quay Street precinct which is distinguished by its substantial 19th century buildings.

Avonleigh, through its form, scale and materials, makes a strong aesthetic and architectural contribution to the Quay Street streetscape and Rockhampton townscape.
