By 2035, Rout Lëns will comprise approximately 1,450 homes and is expected to welcome around 3,000 residents, in the heart of Esch-sur-Alzette.

2026–2027: The First Residential Block

The first residential block will include 185 homes, distributed as follows:

• 47 apartments in Liicht – scheduled for completion in the fourth quarter of 2026
• 95 apartments in D’Haus – scheduled for completion between late 2026 and early 2027
• 43 apartments in a residence developed for the City of Esch-sur-Alzette – to be delivered alongside D’Haus

From early 2027, Rout Lëns will welcome its first 400 residents.

2028–2029: The Second Residential Block

The second residential block will offer a diverse and inclusive mix of housing, including:

• 90 apartments in Häerz – scheduled for completion between 2028 and 2029
• 145 student accommodation units
• 110 homes in a residence for active seniors

By early 2029, Rout Lëns is expected to be home to more than 900 residents.

Additional Affordable Housing

A separate development acquired by the City of Esch-sur-Alzette will provide 42 affordable homes, complementing the first two residential blocks.

🚶 On foot

Everything you need is within easy walking distance. Schools, shops, cultural venues and public spaces are all just a few minutes away.

The Industrial Heritage Promenade, the neighbourhood’s main pedestrian boulevard, connects the historic buildings while providing a safe, landscaped route through the district.

🚲 By bike

A secure bicycle storage area is located outside the Häerz residence, encouraging active and sustainable mobility.

The neighbourhood is also connected to Esch-sur-Alzette’s cycling network.

🚌 By public transport

A bus stop is located just a short walk from the Häerz residence.

In the near future, Rout Lëns will be served by the High-Level Service Bus Corridor (CHNS), providing fast and efficient connections to:

• Esch-sur-Alzette railway station
• Belval and the University of Luxembourg
• Other major employment and activity hubs across southern Luxembourg

🚗 By car

A public underground car park is integrated beneath the Häerz residence, with direct access for both residents and visitors.

✅ Good to know: Rout Lëns is located 15 minutes on foot from Esch-sur-Alzette railway station, 5 minutes by train from Belval, and approximately 25 minutes by car or train from Luxembourg City.

Yes. At Rout Lëns, the geothermal system has been designed at the district scale through an anergy network (energy loop) connecting all buildings and supplying collective heat pumps. This system provides heating, domestic hot water, and cooling during summer.

Why is it sufficient (and reliable)?

• One network for the entire district: A bidirectional energy loop powered by geothermal boreholes distributes energy to every building through a heat transfer fluid, while heat pumps installed in each building deliver heating and cooling.
• Geothermal energy combined with photovoltaics: Rooftop photovoltaic panels generate electricity for self-consumption, helping the district operate without fossil fuels and significantly reducing operational carbon emissions.
• Scalable capacity: The network is being developed in phases, with geothermal boreholes already completed and additional ones planned (e.g. 82 boreholes reaching a depth of 200 metres beneath Block 14, followed by 100 additional boreholes beneath Lot 2).

What about neighbouring buildings?

The system has been designed to be scalable. The anergy network deployed at Rout Lëns is intended to be extendable as far as the City of Esch-sur-Alzette, creating opportunities for future connections beyond the district itself.

Yes. By the time your residence is delivered, the infrastructure required to access your building, move around on foot, and reach the parking facilities is planned to be fully operational for your development phase or plot.

What will be ready when you move in?

• Roads and pedestrian walkways: Kerbs, road-to-pavement connections, stormwater drains, utility access points, and a temporary asphalt surface will be in place to ensure safe and convenient access.
• Essential utility networks: Drinking water, wastewater and stormwater systems, electricity, fibre-optic internet, district heating/energy infrastructure, and public lighting will already be installed—or in the final stages of completion, depending on the phase—to ensure the neighbourhood is fully operational.
• Final landscaping before residents arrive: Approximately six months before residents move in, finishing works are carried out to complete the surrounding public realm, including pavements, lighting, street furniture, and waste sorting collection points. This process is repeated for each development phase.

What if construction is still ongoing nearby?

Your comfort and safety are a priority. Dedicated access routes will be provided to ensure residents can reach their homes without coming into direct contact with active construction sites, particularly via Rue d’Audun.

Parking access

Parking access has been designed to be located at the entrance to the district, helping to minimise vehicle traffic within the heart of Rout Lëns.

For the first development phase, the initial parking facility is scheduled to be operational by the end of 2026, serving the residences within the first block, including D’Haus, Liicht, and the affordable housing developments.

Shared Parking at Rout Lëns: A Convenient Solution for Residents and Visitors

At Rout Lëns, parking has been designed to be simple, intuitive, and suited to a vibrant mixed-use district combining residential buildings, shops, offices, and services. The district’s development plan includes five underground shared parking facilities, allowing parking spaces to be shared across multiple development plots.

Yes. At Rout Lëns, IKO relies on internationally recognised standards and certifications to ensure high environmental performance (particularly in terms of carbon reduction) and occupant well-being.

1) WELL Community™ (district-wide)

The Rout Lëns district is targeting WELL Community™ Certification, which sets performance criteria designed to promote the health and well-being of people across the entire community.

2) WELL Building™ + Carbon Footprint Neutral (selected buildings)

To support the district-wide certification strategy, certain buildings are also individually certified. At the entrance to Rout Lëns, the future school is planned to achieve both WELL Building™ Certification and Carbon Footprint Neutral Certification. At the building level, the project aims to reduce its carbon footprint by at least 30%, notably through the use of low-carbon concrete and bio-based construction materials.

3) Carbon Footprint Certification (progressive low-carbon approach)

IKO also follows the Carbon Footprint Certification, a structured local certification framework with three levels: Checked, Optimised, and Neutral. This certification supports IKO’s ambition of developing a carbon-neutral district.

4) Residential example: Häerz

The Häerz residential development showcases IKO’s commitment to sustainable construction through a high-performance design featuring a low-carbon concrete exoskeleton, a timber structural system, and an A+ / A+ / A+ Energy Performance Certificate (EPC).
