In spring 2026, daa completed the final stage of a multi-million euro lounge programme at Dublin Airport, reopening the 51st and Green lounge in Terminal 2 and the Phoenix Lounge in Terminal 1 completing daa’s lounge renovation programme, which also delivered the refurbished Martello and Liffey lounges in 2025. Belfast International Airport is executing a five-year £100 million (approximately €116 million) interior investment, with a new coffee bar open since December 2025 and a 300-cover premium bar and kitchen under development. Both programmes share one driver: the pre-flight interior is measurable in revenue per square metre, dwell time, and passenger spend.

Aviation interior fit out is a specialist discipline within the broader fit out industry, and the brief that airport clients bring to the design and build process is governed by criteria standard commercial interior design does not routinely address. Passenger flow efficiency, revenue per square metre of concession space, wayfinding integration, and brand differentiation within a constrained airside environment all shape the interior architecture decisions that define a successful airport fitout.

The investment programmes at Dublin and Belfast reflect a global pattern. Future Travel Experience, tracking aviation interior innovation, records sustained lounge and gate investment across European airports in 2025 and 2026, with operators citing the pre-flight environment as a driver of premium passenger choice. The ACI World Airport Passenger Experience Report identifies lounge and food and beverage environments among the highest-weighted factors in passenger satisfaction, directly influencing commercial performance. For fit out contractors, this is a hospitality-grade interior design brief within the constraints of a live aviation environment.

Airport food and beverage environments are typically commissioned through travel food operators such as SSP Group, which holds the concession agreement and manages the design and build process on behalf of the airport authority. SSP is the operator behind the Belfast International programme. Fit out companies seeking to serve airport F&B environments should build relationships with travel food operators and their design consultancies, not airport authorities through standard commercial fit out channels.

The specification requirements of aviation interior fit out align with the certification frameworks fit out companies already operate within. BREEAM Refurbishment and Fit Out, adopted on major airport fitout programmes, rewards acoustic performance, indoor environment quality, and responsible sourcing. Dublin Airport’s 51st and Green lounge doubled seating capacity while delivering a hospitality-grade workspace interiors environment, demonstrating that aviation lounge design draws directly on the interior architecture skills the fit out industry applies across premium commercial interiors and hospitality briefs.

Three actions position Irish fit out contractors to access this market. First, map aviation procurement routes, such as travel food operators, retail concessionaires, and lounge management companies commission fitout, differently from corporate interior fit out clients. Second, build a portfolio in high-throughput public environments like hospitality, retail, and transport interiors, demonstrating phased delivery and commercial interior design in live settings. Third, pursue BREEAM Refurbishment and Fit Out accreditation at practice level, as airport operators increasingly require sustainability credentials alongside hospitality specification capability.

The lounge and terminal fitout programmes at Dublin and Belfast confirm that Ireland’s aviation sector is investing in the interior environment as a commercial asset. The fit out industry has the design intelligence, construction capability, and certification literacy to serve this market. Fit out companies that understand aviation procurement routes and the revenue-driven brief will find a high-specification pipeline entirely outside the commercial office market.
