Helsinki Airport’s strengths include short transfer times, friendly staff and innovative world-class services. We want to maintain these strengths even as passenger numbers grow.

Helsinki Airport expansion in a nutshell

  • The terminal will be expanded by a total of 103,000 square metres. It corresponds to an area the size of the Linnanmäki amusement park in Helsinki.
  • The total area of the terminal in the early 2020s will be more than 250,000 square metres. Then, the terminal could accommodate 10 Finnish Parliament Houses.
  • The number of bridge gates for wide-body aircraft will be doubled from 8 to 16.
  • Baggage handling capacity will increase by 50 per cent.
  • The apron, or the aircraft parking areas and taxiways, will be renovated over an area of 450,000 square metres. The size of the construction site is equal to 90 football pitches.

Development programme extends until the early 2020s

The airport and its services will be expanded in a number of areas. The most significant development projects include:

  1. The expansion of the terminal section serving long-haul traffic, or non-Schengen traffic, and the expansion of the apron. This expansion consists of three new sections: South Pier, West Pier and Plaza. Furthermore, several new parking stands for wide-body and narrow-body aircraft will be constructed, as well as taxiways and other infrastructure serving air traffic.
  2. The development of the Schengen area at the airport (Terminal 1). The extension will be built on the far end of Terminal 1.
  3. Expansion of Terminal 2 (T2). This expansion consists of a completely new entrance with arrivals and departure halls, arrangements for public transport, and an extended area serving traffic to and from Europe, or the Schengen area traffic.

This is how the development programme will proceed

We are expanding the airport under a concept known as “one roof”. This means the new services can be accommodated in a single building, under one roof. Distances will remain short, services easily accessible and passengers will find it easy to attend to their business.

When all operations are under a single roof, transfer travelling will also benefit in the best possible way. Moving from one gate to another will be easy and swift as there is no need to change terminals. Digital services are central to outlining the concept of the new services.

The planning of passenger areas takes account of Finnish materials and decor solutions. Various light and sound landscapes lend the lounges the quality of a genuine experience.


Finavia’s development programme began with the launching of overall planning in 2013. In 2014 and 2015, we carried out preparatory work, such as the demolition and expansion of old buildings. We extended the security control and check-in area in Terminal 2.


The expansion work of the terminal began with the construction of the South Pier in early 2016. More passenger facilities were added to the terminal already in June 2016, as a new lounge featuring a maritime and archipelago theme was opened. These expansions increased the terminal’s floor area by 3,000 square metres. Twelve new departure gates serve passengers waiting for bus transfers to connect them with a non-Schengen-area flight.

In August 2016, we opened an expansion to indoor car park P5. We added two new stories and an expansion to the original building. These expansions added 3,000 new parking spaces to the facility.

A further project to deliver new air traffic infrastructure was completed in October 2016 including a modern engine test site, taxiway AM-AH and maintenance hub.


The first significant milestone of the development programme was reached in July 2017 with the opening of the South Pier furnished with Finnish classics for passenger traffic.

The South Pier, built as an extension to the current gate 53 (formerly gate 38), includes 7,850 square metres of new space for passengers in two stores, one for arrivals, the other for departures. In connection to this, we put into service Finland’s first moving walkway and three brand new passenger boarding bridges for wide-body aircraft, built in a form known as double bridges. This will speed up boarding and add to passenger comfort.

The area of the renovated apron covers a total of 157,000 square metres. We opened two new bridge gates and two outdoor parking spaces for wide-body aircraft.

The first section of a solar power plant to be built on the roof of the extension was also made operational in July 2017.


A large central square, the Plaza, to be built between the South and West Piers will become the heart of the extension. The Plaza is expected to become an impressive space in terms of architecture. Decorated with Finnish wood, its rugged wall and ceiling structures will set an imposing stage for many kinds of events and phenomena.

Various facilities, such as modern security control, shops, restaurants and new services providing passengers with a true experience will be located around the Plaza. The Plaza will add 25,000 square metres of new passenger and baggage facilities to the airport. The Plaza will be opened in early 2019.

The extension of Terminal 1 will be opened in June 2019. The added passenger area amounts to 3,350 square metres. The new facilities will be located on two floors.

The West Pier will be built between the current gates 34–36 of the non-Schengen area. It will be completed during 2020. Read more on the Plaza and the West Pier. The entire expansion of the long-haul area was designed by the architects’ office PES-Architects. The terminal construction project is the responsibility of Lemminkäinen, while the apron will be renovated by Destia.

During 2020, a new, stunning entrance to Helsinki Airport will be opened, and the current terminal T2 will be expanded to cover the area currently used for parking and public transport.

This will make significantly more of the terminal’s facilities available for check-in, security control and baggage drop services, and enhance current arrangements for parking and public transport. It will also make it possible to develop enhanced connections between the airport and other modes of transport. Already by today, Helsinki Airport has established itself as an important European air traffic hub, and is also one of the largest bus and train interchanges in Finland. Helsinki Airport also offers road and sea links to Russia, Tallinn and the Nordic and Baltic countries.

The current arrivals and departure halls will be renewed and, following this renovation, they will be made part or the gate area reserved for flights to and from Europe. The expansion of Terminal 2 will begin after summer 2018 at the earliest. According to the preliminary plan, the entire project will be completed during 2022.

The new entrance to the airport was designed by the architects office ALA Architects. The working group also included HKP Architects and Ramboll Finland. SRV was also selected to participate in the alliance project of the alteration work.

We also intend to introduce improvements to our narrow-body aircraft operations. This work will mainly concentrate on the far end of the current Terminal 1.

The building and inauguration of the new spaces, the launching of new services and the improvement of travel as a whole will take place in stages. The development programme will be split into smaller phases in order to enable flexible reaction to changes in the market situation. The content, cost and schedules will be made more accurate as the planning progresses.
