Innovative urban planning, where heritage and modernity combine for the well-being of residents and nature alike. IKO designs the Next Places!

Urban redevelopment

IKO is proud to bring back to life a site formerly used for steelmaking. Rout Lëns is becoming an emblematic district of the Esch revival. We are boldly rehabilitating a remarkable heritage site to make it the vibrant heart of a brand new, innovative district.

Covering an area of 10.5 hectares, Rout Lëns aims to be an innovative, sustainable and exemplary neighbourhood. We’re creating an urban space where it’s good to live together. A neighbourhood where nature has its rightful place. A neighbourhood with many facets and facilities.


Heritage is transformed into living spaces

IKO has decided to organise the “Lentille Terres-Rouges” site around the alleyway of industrial culture and its heritage buildings: the TT shop, the Turbine Hall, the Möllerei Portico, the Blower Hall and the Switching Station. In keeping with our societal values, these buildings will be converted into meeting places, local shops, cultural centres and sports facilities.


Spaces dedicated to living together

The 1st WELL COMMUNITY pre-certified district in Europe, Rout Lëns is designed around living together. Co-working spaces, multi-purpose rooms, leisure and sports areas, a neighbourhood concierge service and a shared mobility service are all designed to promote harmonious community living.
In some residential projects, the ‘Lënslounge’ will offer additional living spaces on the corridor, to be shared.
Rooftops will also house vegetable gardens, greenhouses and relaxation areas with a breathtaking view over the neighbourhood.

Carbon neutrality

Thanks to the work carried out with Energie Environnement, we are aiming for Carbon Footprint Neutrality certification for the entire district by 2035.

Geothermal energy and responsible consumption

A geothermal system is planned in the district to provide a sustainable solution in terms of energy production for the entire district, for both heating and cooling. The SMART BUIDLING approach will be applied throughout the district to encourage responsible consumption (energy, waste, thermal comfort, etc.).

Grey water heat recovery

A project to recover grey water (water from showers and sinks) is also being studied to supply the heating network for the buildings.


  • Green terraces
    Outdoor spaces are promoted with a community approach to encourage people to live together in the neighbourhood
  • 6,000 sq to cultivate
    6,000 sq will be dedicated to urban farming, to offer fruit and vegetables to part of the population.
  • 700 trees planted
    700 trees will be planted throughout the district to restore nature to this former industrial site.
  • Rainwater harvesting
    Thanks to 50% green roofs, rainwater will be recovered to water the green spaces.

A focus on soft mobility

Rout Lëns will be easily accessible thanks to the recent national trail dedicated to environmentally-friendly travel, known as “Vëloexpresswee”.

The new urban development of Rout Lëns actively promotes and encourages the use of environmentally-friendly means of transport.

Although the car is not a priority in this district, it is nevertheless an integral part of the overall mobility offer. With this in mind, a single car park will be made available to the public, accessible to visitors and located in the centre of the district.

Environmentally-friendly modes of individual transport

Charging points for electric vehicles and car sharing are planned to encourage environmentally-friendly modes of individual travel.

Fast tram

Luxembourg’s future high-speed tram network will include a link through Esch-sur-Alzette, providing a strategic connection between the city, the Cloche d’Or and the centre of Luxembourg. This extension enhances accessibility and connectivity, providing an efficient and sustainable transport solution in the heart of the country.

A neighbourhood for pedestrians

This is a pedestrian-friendly neighbourhood, featuring an alley dedicated to industrial culture that traces the fascinating history of the red earth. To encourage soft mobility, no surface parking spaces are planned, offering a congestion-free environment dedicated to a more sustainable urban experience.

Showcasing Rout Lëns through tools such as the immersive model, the IKO AR application and events for the general public such as the Summer Rout Lëns is part of my daily routine at IKO and enables me to help as many people as possible understand what the future will be like.

Rehabilitating a brownfield site such as Rout Lëns is a challenge that covers both the compatibility of the soil by cleaning up the site and the development of infrastructure in line with the sustainable approach of the district.

Urban Farming

A short circuit approach

The aim is to create a fertile ecosystem that will enable a farmer to feed a neighbourhood as part of a short supply chain approach. This plot of land, with around 6,000 m2 to cultivate, will be developed to offer fruit and vegetables to part of the population. The urban farm will also have an educational role, organising workshops and training courses.

Rout Lëns is a dream come true, with its mixed programming, its cultural offering often overlooked in the development of new districts and its ecological DNA in all its forms.

Discover Rout Lëns bookazine

Every year, IKO publishes the bookazine, a retrospective of the past year which highlights the progress of the project.

Each edition also provides an opportunity to meet those involved in the project and to highlight the collective work that has gone into bringing this new district to life.

Integrating the new district as closely as possible with the existing buildings

Rout Lëns new flats, offices and shops in Esch-sur-Alzette

Rout Lëns is being developed in partnership with the people of Esch and the public authorities. They are all keen to ensure that the new district fits in as well as possible with the existing buildings. As the population of Esch and the country grows, so does the need for infrastructure. Rout Lëns is responding by creating a dynamic new area where life is good.
– 13,770 sq are planned for schools and community services,
– 9,810 sq for private shops and services,
– 8,000 sq will be used as workplaces.

A large number of buildings of all sizes will provide different types of accommodation. Seniors, students, families, couples and singles, whatever their age or social situation, will be able to find a suitable place to live.
Rout Lëns is designed to make everyday life easier for everyone. Soft mobility is encouraged. A cultural and sports centre, a school, a residence for senior citizens, a concierge service and much more, everything is planned. The local and circular economy will also be encouraged.
