The Luxembourg pavilion for the Expo 2025

The Doki-Doki Lux – The Luxembourg Multiverse project from STDM and jangled nerves won the architecture contest for the Luxembourgish pavilion of the world exposition of OSAKA 2025, following the tender process launched in February 2022.

In Japan, “doki-doki” represents a beating heart and is used to express enthusiasm and excitement. The Luxembourgish pavilion of the world exposition of Osaka 2025 is welcoming and intriguing at the same time. It encourages discovery and suggests an unexpected path through the many facets of Luxembourg. It illustrates the 3 themes chosen by Luxembourg in echo to the themes of the exposition.

DESIGNING FUTURE SOCIETY > Unicity: A unique project under a common sky that radiates and communicates beyond its boundaries.

CONNECTING LIVES > Diversity: A landscape made of its different volumes of which diverse origins are gathered in one multicultural community rich of its differences: The Family of Man 2.0

CONNECTIVITY > Terroir / Territory: With its permeable boundaries open to the world and at the same time close to its territory and its unique traditions, Luxembourg encourages discovery and admiration.

SCENOGRAPHY: The Luxembourg Multiverse is global. All the facets of the Luxembourg Multiverse are created and powered by three sources: its creativity, its inhabitants and its territory, corresponding to the 3 sequences of the scenography:

The World Lab / The Family of Man / The Common Home

Luxembourg is where everything takes place: visions become reality in the comfort of a fascinating and charming habitat with a high quality of life – an appeal to protect our common home and create together a sustainable future for all the inhabitants on the planet.

ARCHITECTURE: the pavilion also expresses the 3 themes Unicity-Diversity-Territory. The whole design of the pavilion is focused on the visitors’ and users’ human experience.

A unique and animated roof: the great stretched canvas fulfilling its structural and sealing functions is also a way of communicating with the public. It comes to life in line with the events and the effervescence of the pavilion and following the schedule of the Luxembourgish life. It is a daily meeting with visitors coming to see this performance.

An artificial landscape: composed of various volumes sized following the sequences of the scenography. The placement of the volumes creates outdoors circulation spaces integrating the line in the scenography as well as a forecourt at the end of the visit.

A path of discovery: Visitors’ wellness and quality of experience is the center of the pavilion’s design. As the typical landscapes of the Luxembourgish territory, the path through the pavilion is made of discoveries. Vegetation comes in unexpected forms as on the variable-geometry forecourt, where the mobile trees welcome the visitors or close the pavilion at the end of the day.

CIRCULAR ECONOMY: the design objective goes through a maximum optimization of the used resources. The structure is the most efficient and the lightest possible. The conception preserves the components integrity without transforming them to enable their reuse of equal value. The volumes composing the pavilion are sized on the framework of the Japanese standard tatami and thus match the future needs of any Japanese standard structure.

The pavilion can be fully disassembled. The connecting elements are designed to match the aesthetic of the nation branding logo, making Luxembourg a connector in detail.

The technical concepts combining common sense, tradition and innovation, and based on user experience are numerous: bioclimatism, humidity control, consumption reduction, decentralized ventilation, climate zoning, water harvesting, reduction of water requirements, optimization of technical layouts, long-term investments in renewable energies, reusable standard components.


The Luxembourgish pavilion of the world exposition of OSAKA 2025 will be a modern manifest, coherent and pragmatic of the range of possibilities reachable as part of the application of circular economy principles serving the quality of life and the human experience.
