Rout Lëns stands out as the first large-scale neighbourhood to be both heated and cooled using geothermal energy.

This renewable energy source ensures outstanding energy efficiency while significantly reducing the carbon footprint, positioning the district at the forefront of environmental innovation.

With 1,428 housing units, Rout Lëns offers a diverse range of living spaces, combining private and public housing, a student residence, and a senior residence.

This variety promotes social and generational diversity, creating a dynamic and inclusive community.

Rout Lëns is precertified WELL Community, a global benchmark for health and well being at the neighbourhood scale.

The project is also precertified Carbon Footprint Neutral, confirming a 20% reduction in carbon emissions compared to the Luxembourg average, both in its operations and construction methods.

Rout Lëns’s central location ensures optimal access to the city centre of Esch sur Alzette, whether by train, on foot, by bike, by car or through soft mobility solutions, with a design that is both simple and sustainable.

A 6,000 m² urban farm, combined with green rooftops, creates a genuine connection to nature in the heart of the city.

Built in 1902, the Magasin TT served as a supply hub for the steelworks and its workers, while also housing a brewery.

Its industrial architecture, featuring three levels, pilastered facades and a metal framework, gives it significant historical and heritage value.

As the first restored building in Rout Lëns, it is regaining its spirit of conviviality with a 550 m² brewery and a 200 m² south facing terrace, blending authenticity with modernity.

Starting in June 2026, the Magasin TT will become a landmark where heritage and gastronomy come together at the heart of the district.

Built in 1901, the Turbine Hall generated the electricity required for the steel industry. This large rectangular building, with varying heights, a striking structure and remarkable facades, holds significant architectural and heritage value.

Following its transformation, it will house the Sports Exhibition and Convention Center, combining a museum, exhibitions and events dedicated to sporting history and the community.

Carefully restored, the Turbine Hall will blend authenticity and innovation to become a landmark of culture and sharing, with its opening scheduled for 2029.

This building, reminiscent of a giant centipede, was once used to fill wagons with molten iron.

In the new project, its elevated hall will be rebuilt. The space between its metal legs will remain open, allowing passers by to admire the structure, enhanced with climbing green curtains such as hops, which will supply the nearby microbrewery.

Once restored, the portal will also house retail, offices and a coworking space, becoming a lively meeting point where heritage and urban life come together, directly adjacent to the high service level corridor.

A blower is a key component of a blast furnace, supplying the combustion air required for its operation.

The distinctive architecture of the Blower Hall, built in the 20th century, makes it a powerful symbol of the site. Its central height reaches 20 metres.

The real estate project plans to preserve it in its current form with minimal alterations.

Its very thin walls and large glass bays make it impossible to heat, which makes it the ideal place for sports and leisure activities, reinforcing its role as a vibrant and lively space at the heart of the district.

Much more modest in size, the Signal Tower also dates back to the 20th century. It once directed the trains serving the site.

Its unique mushroom-like shape has earned it several nicknames, such as the “U-boot,” meaning submarine, or simply “the mushroom.”

It will be converted into a unique place to stay for travellers seeking out original and offbeat experiences.
