From the 1840s, an itinerant Presbyterian minister was present on the Darling Downs, however, it was not until Reverend Thomas Kingsford arrived in Warwick in 1851 that the church had a permanent presence in the district.

It may be that the land was unsuitable in some way as that same year the church purchased an alternate site on the corner of Fitzroy and Guy Streets for the sum of £36.

[1] Deposits of continental sandstone in the district surrounding Warwick provided a ready source of good quality building stone for the town.

It is difficult to assess the full extent of McCulloch's work in Warwick due to inadequate records from his yard; however, he is known to be responsible for a number of churches and commercial buildings, as well as the Court House, Town Hall, Sisters of Mercy Convent and the Railways Good Shed.

The local newspaper, the Warwick Examiner and Times reported on 26 November 1870 that the material was not only cheaper than timber but well suited to the Queensland climate as it was "cool, clean and almost noiseless when walked over" and commented that the building was "one of the best ornaments the town possesses".

During the time that Reverend Robert Fraser was Minister (1882–87) he made an interest-free loan of £300 to the Committee of Management which was used to strengthen the roof and erect pinnacles on top of the buttresses.

This work is attributed to local builders, architects and surveyors, Wallace and Gibson, however, it is not clear whether they designed the porch as well as constructing it.

It appears that the entry porch was re-modelled in 1950 through a financial gift of Charles and Esther Counsell and it is likely that the main roof was tiled and the pinnacles atop the buttresses were removed at this time.

[1] The Warwick Uniting Church is a simple sandstone structure, rectilinear in form, with a stone entry porch on the front eastern facade of the building.

The vestry and choir room is a small rendered masonry structure with a pitched roof added to the western end of the building.

[1] The interior of the church has an open roof structure consisting of arched brace trusses with the ceiling lined in painted, diagonal timber boarding and acoustic tiles.

[1] A window has been removed on the southern elevation and has been replaced with a recent door opening to a covered walkway that links the church to the new hall.

Lawn comprise the eastern and northern parts of the site, with a wide concrete path leading to the entry door of the porch flanked by mature trees including two large Silky Oaks and some smaller conifers.

The building makes a significant contribution to the streetscape, located on a prominent intersection of the town that includes Warwick Courthouse and Leslie Park.
