Three new buildings totally over 25,000m² will be constructed. These include a 5-level Courts and Judiciary building with 14 new court rooms, a 3-storey administrative support building with space for registries and support agencies and a single level security arrivals building.

The new courts building is designed for optimal spatial efficiency through vertically stacked courtrooms and centralised circulation zones and services. Court rooms are standardised and used for either criminal or civil cases. The ceremonial Banco Court is able to be converted into a major conference facility.

The building structure is overlaid with screens that add depth and colour to the facades with the feature screen to the ceremonial court constructed from woven concrete structure emblematic of Papua New Guinean billum bags symbolic of the interweaving of the diverse PNG cultures.
