建物の外側では、各フロアの異なる配置が、各階に外部のプラットフォームを形成しています。これらのプラットフォームは、鮮やかな赤い階段でつながれており、その階段は建物を巻き上がるように伸びて、屋上へのルートを際立たせています。このルートは一般に無料で開放されており、建物は港を見渡す展望塔としての役割も果たしています。

「Portlantisは目を引く存在であり、灯台のようでもありますが、それと同時に一種の見張り塔でもあります」MVRDVの共同設立者であるウィニー・マースは言います。「ロッテルダムに住んでいると、港は地平線の向こうにあって、『あっちの方にあるもの』という感覚で、多くの人はそこで何が行われているのか実はよく知らないのです。Portlantisは、人々に港で何が変化しているのか、それが都市とどう関係しているのか、そして自分たちの都市での暮らしにどのような影響を与えているのかを探る手がかりを提供します。それは極めて効率的に行われます。まるで物語を伝える機械のように」

この建物の素材はシンプルかつ工業的であり、サーキュラーエコノミーの原則に従うことで持続可能性を追求しています。この構造体は解体可能で、その部材は容易に再利用できるようになっています。また、外装パネルは製造元との取り決めに基づき、パネルの寿命が尽きた時点で返却されることになっています。建物の基礎部分でさえ、コンクリート杭を使用しない設計となっており、痕跡を残さないようになっています。Portlantisの持続可能な素材に加えて、運用においてもエネルギー中立を上回る性能を備えています。高効率な断熱とヒートポンプの導入により、この建物のエネルギー需要は比較的低く抑えられています。専用の敷地内風力発電機のおかげで、このプロジェクトは使用するエネルギーよりも30％多くのエネルギーを現地で発電しています。

本日の盛大な開館式に続き、Portlantisは2025年3月22日に一般公開されます。

A machine for storytelling: MVRDV’s Portlantis offers visitors a new perspective on the Port of Rotterdam

For centuries, the city of Rotterdam and its port have grown together in a symbiotic relationship. In the 21st century, the Port is embarking on one of the most significant changes in its history, as it transitions to sustainable, low-energy operations. How can this change be experienced by the public, making sense of the complexity of the port? Opening today, the MVRDV-designed Portlantis is a visitor and exhibition centre for the Port of Rotterdam located at the port’s western-most point. Comprising a stack of five rotated exhibition spaces, the building stands out from its surroundings with its crimson-red public route from the dunes to its rooftop, while offering spectacular views in all directions of the North Sea, the coastline, and the port.

Occupying a prominent location on the beach of the port’s Maasvlakte 2 artificial land extension, Portlantis creates a beacon that is visible from afar. It takes a practical, no-nonsense approach to its educational task, channelling the spirit of the port with its simple functionality, dramatic presence, and industrial materials. The shape of the building is a direct response to the activities taking place inside and out: each floor is square in plan and has a large panorama window that frames a different view of the surroundings. The orientation of each floor, and the direction its main window faces, corresponds to its function: on the ground floor cafe, this window faces westward and provides an intimate view of the dunes, while diners in the fourth-floor restaurant can enjoy views of both sunsets over the North Sea and the illuminated skyline of the port at night.

The permanent exhibition, designed by Kossmanndejong, is spread over the three levels in between as objects in this industrial environment. In the exhibition, each level addresses a different theme, and the panorama windows are focused on elements within the port that enhance the content of the exhibition. At the centre of the building is a 22-metre-tall atrium that functions as an exhibition space in its own right. A kinetic sculpture hangs in its centre, with a model of the Port of Rotterdam greeting visitors on the ground floor. This dramatic space is emphasised by the mirrored ceiling, which doubles its apparent height, and by the entrance from the ground floor, in which a rotating door conceals the exhibition until visitors enter the voluminous heart of the building.

On the outside of the building, the different orientations of each level create platforms on each level. These are connected by bright red staircases that twist their way up the stack, highlighting the route to the roof. This route is accessible to the public for free, allowing the building to act as a viewing tower over the port.

“Portlantis is a beacon, it’s eye-catching, but it’s also a kind of watchtower”, says MVRDV founding partner Winy Maas. “When you live in Rotterdam, the port sits on the horizon – it’s ‘over there’ and many people don’t really know what goes on there. Portlantis gives people a way to investigate, to see how things are changing in the port, how that relates to the city, and how it affects the life they live in the city. It does this extremely efficiently – like a machine for storytelling.”

The building’s materials are simple and industrial, seeking to be sustainable by following circular economy principles. The structure is demountable so that its parts can easily be reused, and the facade panels will be returned at the end of their lifespan under an agreement made with the manufacturer. Even the building’s foundation, which avoids the use of concrete piles, is designed to leave no trace. In addition to the sustainable materials of Portlantis, it is also a better than energy-neutral in operation. Efficient insulation and a heat pump mean that the building’s energy requirements are relatively low. Thanks in large part to a dedicated on-site windmill, the project locally generates 30 percent more energy than it uses.

Following today’s grand opening ceremony, Portlantis will open to the public on March 22nd, 2025.
