Amsterdam Schiphol airport released design plans for its terminal expansion project, set to increase capacity by 14 million travelers.

The expansion is scheduled to open in 2023, joining the existing Departure and Arrival Hall 1, and retaining the airport’s single terminal layout. The layout is praised for its simplicity.

Dutch firm KAAN Architecten designed the new building, the first permanent expansion since 1993 when current Departure Halls 3 and 4 and Arrival Halls 3 and 4 were built.

“The most inspiring architectural and planning DNA at Schiphol for our design team is that of the 1967 Departures Hall. DNA which is characterized by abundant daylight, simplicity of space and a substantial spatiality,” said the design firm. “It is particularly striking that materials and construction are so minimally conspicuous. The repetitions that defines the space — the row of columns, the information panels, the ticket kiosks, the façade ribs, the ceiling lamps — all contribute to a calming rhythm.

“This is the true essence of Schiphol’s DNA: functionality is a priority — an exacting rather than bare functionality — it is exacting in how the functionality embeds comfort, daily ease of use and a suitability of purpose. This leads to a natural simplicity.”

Jos Nijhuis, CEO, Schiphol, said the design “contributes to excellent processing, provides optimal support to passengers, contributes to our sustainability ambitions and is future-proof.”
