[1] Wickham House, a five-storey masonry building, with basement, was constructed in 1924 to a design by Francis R Hall and built by FJ Corbett.

[1] Wickham Terrace was evolving into an area of boarding houses and homes, schools, clubs and medical rooms.

On 6 January 1923, Hall called for tenders for the construction of "professional flats at the corner of Wickham terrace and Upper Edward street (to cost £25,000)".

The building consists of five floors and basement, that portion facing Wickham Terrace consisting of two shops, one occupied by Mr DJ Clark (Chemist) and the other by Medical and Surgical Requisites Ltd... the main entrance... vestibule... is panelled and floored in marble with swing doors of bevelled glass..."[1] Wickham House was part of the interwar redevelopment of the medical precinct along Wickham Terrace, which included Brisbane Clinic (Lister House), Ballow Chambers, Inchcolm and Craigston.

A fourth doctor, Dr John Rudolph Sergius Lahz was severely traumatised due to the incident.

George Boland, a patient of one of the doctor's in the building, attempted to stub out the bomb only to have it explode and maim his hand.

Following his rampage, Kast locked himself in the office of Dr Lahz, within Ballow Chambers, where he shot himself and ignited another bomb.

The tragedy was reported in the Courier-Mail on Friday, 2 December, as "...a horrible crime ...[that]...sent a shock of horror through the city and all Queensland".

[1][2][3][4] Wickham House continues to accommodate medical specialists, maintaining the purpose for which the building was designed and constructed.

Their construction constituted the second phase, the first being in the 1880s, of the Terrace's growth as a medical precinct, and was indicative of new directions toward specialist medicine in Queensland in the interwar years.

Prominently located at the corner of Wickham Terrace and Upper Edward Street, Wickham House is an accomplished and intact building which is important in demonstrating the principal characteristics of a purpose-built interwar medical office building, including in the restrained design the assertion of medical specialist prestige.
