There being a number of Presbyterians living in Wahroonga they pressed for the establishment of their own parish rather than the planned Home Mission station.

[1] The foundation stone of the new church was laid by the then Governor of NSW, Sir Dudley de Chair in 1929 and the first service held therein on 26 April 1930.

The main entrance to the church complex retains its original light fitting set in the tops of these piers.

An octagonal stair turret, with copper spire, on the north west corner, leads up to the organ gallery above the entry.

At the southern end of the church an arcaded brick porch links two vestries, which are located either side of the chancel.

The church contains a very fine collection of high quality paired lancet stained glass windows, 11 of which are the work of Norman Carter (see images and a detailed description in the book St John's Wahroonga - the first 100 Years 1898-1998 Ed.

[1] The interior of the church is face brickwork with a panelled timber dado running around the walls below sill height.

The ceiling is timber boarded with exposed rafters and is supported by hammerbeam trusses of an unusual and elaborate design.

A deep carved timber cornice, featuring vine leaves, runs around the top of the walls above two rows of corbelled brickwork.

[1] The timber floor slopes from the entry down toward the chancel, which is on raised platform, containing the Pulpit, Lectern and Communion table with chairs for the officers of the Church.

The nave of the church is filled with benched pews (original) arranged with a central and side aisles.

The church is lit with large amber glazed lanterns (original), recently modified for halogen lights.

The western wall facing Coonanbarra Road repeats themes from the church building in its detailing.

The northern and southern walls are buttressed, and where the arcading that links this building to the church meets the Little Hall, there is a stone capped gabled parapet.
