He died in 1877 and management of his estate passed to his eldest son, William Stephens, a politician, businessman and first mayor of South Brisbane.

This second Cumbooquepa was built on a higher part of the site, a short distance from the original which was demolished in 1890 to make way for the south coast and southern suburbs railway line.

[1] An L-shaped two-storeyed educational block was built in 1920 to a design by architects Chambers and Powell with an extension containing a gymnasium and chemistry and biology laboratories completed in 1926.

[1] A two-roomed library building designed by Thomas Brenan Femister Gargett as a memorial to CE Harker was opened in 1935 and extended to include an art studio in 1939–40.

[1] Somerville House comprises structures and landscaping elements, including paths, walls and cuttings on the large triangular block bounded on the north side by Vulture Street and on the west by the railway line.

[1] Cumbooquepa, a single-storeyed masonry and timber house with terracotta tiled and corrugated iron hip roofs, is located on the highest part of the site overlooking the Brisbane River to the north.

Originally E-shaped in plan, the long northern facade connects central, eastern and western wings arranged around two verandahed courtyards.

This front facade is embellished with arches, pediments, quoins, cornices, parapets, balustrades and pilasters with Ionic capitals that are rendered to contrast with the brickwork.

Stained glass in two fanlights and tall arched niches in its four corners depict Shakespearian characters: Touchstone (As You Like It), Jaques (As You Like It), Portia (The Merchant of Venice), Beatrice (Much Ado About Nothing), Viola (Twelfth Night) and Rosalind (As You Like It).

[1] The dining room, accessed from a breezeway at the rear of the entrance hall, has rendered walls with timber wainscoting and an ornate coved and panelled ceiling that is lined with diagonal tongue and groove boards.

The former library is a one-storeyed buttressed brick structure with contrasting rendered details including castellated parapets, window frames, arches and base and has steeply pitched terracotta tiled roofs.

Cumbooquepa is an uncommon example of a large late 19th century residence, which is exceptional for its architectural quality, lavish interiors, and prominence as a landmark.

Cumbooquepa has a special association with the Stephens Family, CE Harker, MK Jarrett and the US Army and Brisbane architects, GHM Addison, and TBF Gargett and artisan William Bustard, and are important examples of their work.
