Formerly a heavily forested cocoa plantation, the acquired site is isolated from utility infrastructure as a nearly self-sufficient compound. Prime power generation, rainwater collection, wastewater irrigation and other energy recovery methods will support the eight new buildings including a new office building, Deputy Chief of Mission residence, Chief of Mission residence, six staff residences, and a recreation facility. Materials of the residential compound draw from a contemporary design of stucco, limestone cladding, and hardwood rain screens.

The perimeter security improvement plan, a design concept approved by the National Capital Planning Commission (NCPC) and the Commission of Fine Arts, will secure the Harry S Truman Building on the 11.8-acre site, protect employees and visitors, and improve the aesthetics of the streetscape. Five new security pavilions with green roofs will serve as screening facilities to enter the building. A landscaped protective perimeter, consisting of attractive fences and garden walls, will enhance general security. C Street will be redesigned as a boulevard with restricted vehicular access, and shaded tree-lined sidewalks.

Located in the Harbour City development complex, the vision for the compound emphasizes compatibility with the local climate and also echoes a marine theme to reflect the coastal region of Papua New Guinea's maritime culture. The site is designed with two distinct zones; a representational front lawn and entry plaza and a rear recreation area that provides an aesthetic balance between diplomacy and community. Aimed to become Papua New Guinea's first LEED® Certified building, the project serves as a focal point for Harbour City encouraging renewable energy technologies while incorporating indigenous design aesthetics into a prototype of U.S. embassy designs.

Located on a site adjacent to the King's Palace, this new embassy compound is bordered by a Serbian military compound to the west, and diplomatic complexes and high-end residential to the north and east. Due to the historic nature of the neighborhood, the design requires approval from the Serbian Institute for the Protection of Cultural Heritage. Designed with contemporary façades that respond to the progressive, forward-looking ideology of Serbia, the embassy will utilize curtain wall systems, aluminum composite wall panels, and granite stone cladding to give the buildings a sleek, modern appearance.

Constructed in the 1920s, designed by George Oakley Totten, the building served as the Ambassadorial Residence for the Embassy of Spain until 2004. The Embassy of Spain asked KCCT to transform the former residence into a cultural center— Spain/U.S. House. The ground level space will be designed to support exhibitions, lectures, live productions, a café, and kitchen. Upper levels will now accommodate support offices and media resource center. The former Chancery on site will become a black box theater for live performances, concerts, and special exhibitions.

Partially funded by the American Recovery and Reinvestment Act of 2009, the Foreign Affairs Security Training Center will consolidate 19 scattered facilities and the training functions of the Diplomatic Security Service program. KCCT is developing the program of requirements for the facility and creating a master plan for the selected site. After preparing cost estimates for implementing the master plan, KCCT will develop conceptual level (35%) design/build bridging documents. The entire project will surround a sustainable agenda.

This sustainably conscious compound employs design concepts to respond to the arid climatic conditions of the region while managing the annual heavy rains that have caused damage to nearby areas. On site, storm water retention ponds and underground retention systems integrated with the landscape capture and manage storm water run-off while reduced on-site paving contributes to the overall run-off. The exterior design of the New Office Building incorporates local stone cladding and uses rain screen systems consisting of metal panels and porcelain tiles. The design-build construction schedule is 36 months.
