The municipal administration has a new address

 

A new city hall is being built in Differdingen. Originally planned as a renovation and expansion, the project is evolving into a completely new, more modern, functional, and energy-efficient building due to unforeseen construction defects.

Due to the construction work, the municipal administration has been relocated to two sites (Mandela residence & former hospital) for a period of 3-4 years. After the renovation work, the City of Differdange will have a modern town hall, in which our departments will be able to serve the city’s citizens as best as possible.

The citizens’ office and other departments with a lot of public contact are located in the Nelson Mandela building, which is only a two-minute walk from the town hall.

Departments
· Reception / Citizens’ Office / Registry Office
· Customer Service
· Traffic and Mobility Department (Guichet)

Parking
You can use the Aalt Stadhaus parking garage (rue Saint-Nicolas) or the car park on Place Nelson Mandela. Please note that during the renovation of the town hall, part of the car park will be closed for construction equipment.

In 2026, the project to modernize the town hall took a major turn. Initially planned as a renovation and extension, the project evolved into the construction of an entirely new building that is more modern, more functional, and more energy efficient.

Structural defects that could not be anticipated

During the demolition of the existing building, which dates back to the 1960s, in-depth analyses revealed critical problems: the concrete slabs, which were supposed to be solid and 27 cm thick according to the original plans, are in fact only 6 cm thick. The metal reinforcements are severely corroded, the concrete is of insufficient quality, and the structure no longer meets fire safety standards. The foundations and soil conditions also make it impossible to restore the existing structure.

These discoveries, which were impossible to detect while the building was occupied, make any renovation technically and financially unfeasible.

A city hall for the 21st century

In light of these findings, the municipal council is proposing the construction of a new building, which will offer numerous advantages: 1,000 m² of additional space, 38 additional workstations, 20 integrated parking spaces, municipal archives in optimal conditions, and full accessibility for people with reduced mobility.

In terms of energy, the new building will enable a 48% reduction in energy consumption, thanks in particular to photovoltaic panels and optimal compatibility with the district heating network.


Start of construction: January 2025
End of construction: December 2029
Estimated cost: 43,000,000 €
