赫尔辛基机场扩建部分的完工为航空之旅又增添了一丝冒险与浪漫的色彩。从50年代起，扩建工程就分阶段多次实施，逐步改进了机场的功能。2016年，机场运营商Finavia发起了2号航站楼改造与扩建的设计竞赛，内容包括将出发和到达大厅搬迁至新楼，以便将现有2号航站楼的出发大厅改造为申根专用。

The newly opened expansion of Helsinki Airport brings adventure and romance back to air travel. It also improves the functionality of the airport, built in multiple phases starting from the 50s. In 2016, the airport operator Finavia launched a design competition for  the expansion and modification of terminal 2. The competition task included relocating the departures and arrivals halls to a new building so that the existing departures hall of terminal 2 could be turned into Schengen gate areas.

新落成的航站楼占地43, 000平方米，包含出发和到达大厅两个不同体量，分别由木制天花板与蓝色空间为标志。除出发与到达大厅外，两个体量中还分别植入了一个多式联运旅行中心和一个集安全设施、海关和行李提取为一体的控制中心。由于扩建的新建筑与旧建筑直接相连，功能流线依旧延续了将出发和到达按照不同层进行分流的设计。

The 43,000 SqM departures and arrivals building comprises two distinct volumes; the first defined by its wooden ceiling, the second by its blue color. In addition to the departures and arrivals halls, the first volume contains a multimodal travel center, and the second the areas for security control,  customs and baggage reclaim. As the new building connects directly to the old one, it follows the traditional logic of separating the flows of departing and arriving passengers onto different levels.

多年以来，建筑师们都不断追寻着更轻盈、更灵动的屋顶与天花板设计，在赫尔辛基机场也是如此，旧建筑的天花板已展示出既轻巧又严密的构造，新出发大厅的设计更以轻盈姿态化解了极端重量。

For years, architects have aimed at creating illusions of flying and of overall lightness with their designs for terminal roofs and ceilings. This is true also at Helsinki Airport – the ceilings of the older construction phases are seemingly lightweight and tectonic. Even the ceiling of the new departures hall plays with the concept of lightness but combines it with extreme weight.

无柱的出发大厅和巨大的入口雨棚都得益于钢结构的运用，钢骨架隐藏在预制木材单元制成的天花板内，仅从值机区中央天窗的深凹处可以看出它的厚度。从整体看上去，可塑性极强的结构仿佛漂浮在空中。云杉板的排布模拟了等高线的形式，形成倒置的三维地图，将乘客的思绪引向跑道上方的天空。

The use of steel structures has enabled the construction of both the column-free departures hall and the massive entrance canopy. These structures are hidden inside the ceiling made of prefabricated timber units. Its thickness is noticeable when looking at the deep recess of the skylight in the center of the check-in area. The plasticity of the overall form however makes the ceiling seem as if it was floating in the air. The flowing shapes of the spruce boards resemblig contour lines turn it into an upside-down version of a three-dimensional map that leads the passengers’ thoughts towards the sky above the runway.

新出发大厅和旧航站楼之间的低层蓝色安全控制体量在远处也清晰可见。颜色从外延伸至建筑内部，使进入出发大厅的旅客第一时间注意到值机区后面的蓝色区域。除提高可识别性的作用外，蓝色也能够在安全控制的紧张时刻起到安抚与镇定的作用。

The low-rise blue security control volume between the new departures hall and the old terminal is recognizable  already  from  further  away.  The color continues from the exterior cladding to inside the building. When entering the departures hall, the departing passengers will immediately notice the blue area behind the check-in kiosks. In addition to improving recognizability, the blue color also has a calming effect in the sometimes- stressful security control situation.

在较低的楼层，到达的乘客在通过海关后将首先看到名为“Luoto”的自然立体模型。“Luoto”将芬兰自然特征与日本园林艺术相结合，通过大型花盆中的树木、灌木和石头搭建起微型景观。站在上方出发层的旅客可以通过值机区中间的菱形开口望见“Luoto”，而站在楼下向上望，起伏的木制天花板和透过天窗的蓝天将映入人们眼中。

On the lower level, the first thing the arriving passengers see after having passed through customs, is the ‘Luoto’ nature diorama, a freeform installation with living trees, shrubs and stones in a large cor-ten planter. ‘Luoto’ combines the characteristics of Finnish nature with Japanese garden art. It is visible also from the upper departures level through the diamond shaped opening in the middle of the check-in area. Whereas when looking up through the opening, the arriving passengers will see both the wooden ceiling and the blue sky visible through the skylight above.

扩建项目依据BREEAM优秀标准建造，是芬兰首批入选该联盟的项目之一。扩建后的机场已于2021年12月1日与公众见面，并将在2022年夏季前全面投入使用。随着翻新工程的完成，新的主入口和到达大厅将能够服务于全部乘客，在一个航站楼的屋檐下实现全部功能。

The expansion was built according to the BREEAM Excellent standards as one of the first alliance projects in Finland. It opened to the public on December 1st, 2021 and will be fully functional by summer 2022. Once also the ongoing renovation  works have been completed, the new main entrance and the new departures and arrivals halls will be able to serve all passengers: the airport will then have all its functions under one roof, practically in one terminal.
