The Public Trust Office was established by the government in 1873 to provide estate, will and trustee administrative services. By the early 1890s New Plymouth was served by a local agent, and got its own district public trustee in 1919 during a period of decentralisation from the head office in Wellington to the regions. Decentralisation required ‘new and more commodious buildings’ and the New Plymouth office was one of many built throughout the country in the 1920s. Thomas Bates, the town’s leading commercial architect, designed the stripped beaux-arts classical style reinforced concrete building in early 1920 and construction was complete by October 1921. A 1925 addition enhanced and extended the symmetry of the existing building along the Queen Street elevation and doubled the building’s floor area.
The King Street front elevation has a centrally located entrance flanked by two segmented semi-circular windows. Compared to other Public Trust buildings of similar age (such as the Public Trust Building in Napier, List No.1167) the New Plymouth office is modest in size and appearance, with the only exterior decorative elements being the keystones adorning the tops of the windows, a moulded cornice line, and parapets with blank rectangular escutcheons. Michael Fowler described its architecture as evoking confidence and comfort to its clients through its ‘no-nonsense frontage and ... inspired and confident lettering’, which proclaimed the building’s name and function on the front facade. It is one of five Bates buildings in a one block radius.
In 1983 the interior of the building was altered to accommodate commercial offices. Ten years later it was threatened by a proposed K-Mart development; this did not eventuate and the building was sold by the Public Trust in 1995. Demolition loomed again from 2003-2005 when the owner proposed building a three storey apartment on the site. These plans did not gain traction with the public and it was resolved to retain the historic façade and convert the building for residential use. In 2007 it was sold as a gutted shell and converted the following year into a residence with two self-contained units rented as boutique accommodation.
