Hierarchy Group were the Lead Designers for the expansion of Christchurch Airport's retail and hospitality offerings in International Departures, which included the creation of a new Aelia Duty Free Store spanning 2,000m². The design of the Aelia Store drew inspiration from iconic features of Christchurch and the South Island to create a strong sense of place within the store. For example, an angular timber mountain-scape ceiling was designed to represent the Southern Alps and connect different zones together. A graffiti wall featuring South Island flora and fauna served as the backdrop for the NZ Gifts area. A bespoke floral wallpaper highlighted the fragrance area and referenced Christchurch's reputation as the "Garden City," while other tourist attractions such as the Christchurch Tram, New Regent Street, and the Antigua Boat Sheds were also represented. To ensure passengers flowed naturally through the space, a neutral palette of timeless and elegant materials was used as a background to the more themed elements. The project was delivered over a seven-month build period that was split into three stages. One of the challenges was to ensure the existing Duty Free store could operate throughout the build, with minimal noise disruption to passengers and airport staff. The success of the project was due to thorough planning during the early design stages and clear and open communication with all parties involved throughout the project.
