Luxembourg's Ministry of Mobility and Public Works is planning to build an innovative, sustainable office complex in the European Quarter on the Kirchberg plateau. The European Stability Mechanism (ESM) has been chosen as the main user of the offices, which it will share with the administrative units of the Luxembourg State.
The project corresponds to the objectives for the future of the Quartier Européen Sud: improving the quality of life by (re)introducing the human scale, encouraging soft mobility, developing the cycling network, improving the parking system and making better, greener and more sustainable use of the currently unused areas along the main boulevards.
Together with UNStudio, we planned three main buildings: ESM HQ, a building for the Luxembourg government and the "Luxembourg" building. They were carefully positioned on the site to ensure sufficient setbacks from the site boundaries.
The site features several open, accessible and green public spaces. Three squares and two large courtyards are linked to each other, both visually and physically by stairs and ramps.
Water features and public benches are planned for the first square - "Place de l'eau" - to the southwest. It becomes the security entry point for the ESM headquarters and the "Luxembourg" building.
On the other side, in the north-east area of the site, the "Food Plaza" offers gastronomic experiences with food trucks, food stalls and a restaurant with terrace, set in a micro-forest home to numerous species of flora and fauna. The ESM entrance courtyard, which is partially used as an urban greenhouse, is visible from here and creates an access for employees.
A gently sloping path under the trees leads to the third square - the "Place du Sud" located in the central area of the plot. Its main role is to attract passers-by, employees and visitors to the Kirchberg Valley. This square is directly linked to the inner courtyard, with green spaces and areas for outdoor sports. From here, it's possible to access the Luxembourg government building, as well as the fitness center and restaurant.
All these carefully designed and programmed open park areas have a positive influence on the site's environment. The wealth of facilities and the variety of outdoor uses and activities form an excellent basis for the desired public regeneration of the Kirchberg plateau.
The "Kirchberg Valley" is a state-of-the-art office campus that aims to create a lively environment not only for employees, but also for the public: visitors, neighbors and commuters who come to work at Kirchberg every day. It's a human-centred workplace that meets current and future needs, and connects the Rue Alcide de Gasperi with the Rue Antoine de Saint-Exupéry thanks to its increased permeability and multiple integrated pedestrian walkways.
All three buildings follow the same design principles, accommodating the same program and layouts, whether cellular or open-plan offices, or a mix of both. The spaces can adapt to changes in working style, reorganization and change of function, thanks to a flexible and resilient design.
The cradle-to-cradle approach translates into standardized construction elements of the same height for partitions in all three buildings. Identical components can be reassembled and reused to suit different office and meeting room configurations, without the need for complex modifications to the heating, cooling or ventilation systems. Components are organized according to their cycles of use.
The workplace concept is based on modularity and standardization, with a high degree of flexibility. Our aim is to create an open, creative atmosphere with a variety of working and social spaces, to encourage interaction, communication and exchange between different teams or departments.
The roofs of the buildings will be green and accessible to employees. Lower roofs will connect office interiors to outdoor green spaces and communal food gardens.
