The homestead includes a Georgian farmhouse understood to date from c.1830, a kitchen-garage wing on the north eastern side, probably dating from the same time and a cottage wing on the north western side dating from c.1836.
Both wings are now joined to the original house to form a courtyard entrance area facing O'Connell Road.

The original farmhouse has a verandah which originally surrounded the house entirely and is believed to be one of earliest examples of a wrap-around verandah built in Australia.
The verandah has been enclosed on two northern corners to form rooms that now connect the farmhouse to the cottage and the kitchen-garage wing.
An "outdoor" room has also been added c.1980 near the southwest corner of the farmhouse.
The verandah has a separated roof with a lower pitch than the main roof, a solution favoured aesthectially from the mid-1830s.
The walls of the farmhouse are rendered brickwork.
A partition wall within the kitchen wing is constructed of pise.
The original windows on the farmhouse are timber-framed, double-hung with six lights per pane, fine glazing bars and mostly original glass.
The original entrance (facing south towards the river) has a formal symmetrical facade with a central door and half round fan-light with 8 panels.
The original shingles for the roof, manufactured locally, are believed to be still in place beneath the corrugated iron roof.
The most intact part of the original farmhouse is its hallway.

John West had several male convicts listed under his household during the period the three sections of the homestead were constructed, so it is believed to be convict built.

The homestead was originally designed with the front entrance facing the original road to the south.
The construction of a new road to the north c.1860 (O'Connell Road) necessitated a changed orientation for the house to the north, utilising what was originally the rear facade and courtyard, which now acts as the entrance to the homestead.
