A major new urban development project in Strassen, led by the developers of “Les Jardins de Luxembourg”.
With two new strategic developments in Strassen, this project marks the return of a major player in a rapidly evolving market.
The development team behind the landmark project LES JARDINS DE LUXEMBOURG in Merl (2006–2024) today announces the launch of a new urban development in the heart of Strassen. United under a single identity, HERITAGE, the two developments KIEM and GAASCHTBIERG open a new chapter for residential and mixed-use real estate in Luxembourg.
Designed as a coherent, responsible and sustainable development, HERITAGE aims to bring significant added value to the western part of the capital.
Located on two strategic sites along the Route d’Arlon, HERITAGE continues the values that made Les Jardins de Luxembourg successful: a qualitative approach, long-term vision, high construction standards, and a constant commitment to sustainability.
The project aims to create two human-scale neighbourhoods combining housing, retail, offices, and large green areas to meet the needs of residents, investors, and local stakeholders.

55–61 Route d’Arlon
KIEM offers a balanced development integrated into an existing and dynamic urban environment.
Designed as a modern living space, KIEM prioritises accessibility, proximity, and the harmonious integration between residential functions and economic activities.
Programme

240–260 Route d’Arlon
With a remarkable surface area of 33,000 m², GAASCHTBIERG represents one of the most significant developments in Strassen.
GAASCHTBIERG stands out for its optimised density, generous greenery, and a subtle balance between residential living, services, and natural spaces.
Programme
Strassen is today one of the most sought-after municipalities in Luxembourg, benefiting from immediate proximity to the capital, a dynamic commercial environment, and modernised infrastructures.
HERITAGE aims to support this evolution by expanding and modernising the supply of housing, offices, and retail spaces while strengthening the attractiveness of the area and the quality of life of its residents.
HERITAGE is based on a clear vision: building reliable and sustainable neighbourhoods supported by experienced actors.
“Les Jardins de Luxembourg” (owned by the investment fund Prime Properties) provides a solid financial structure and a reassuring acquisition model for buyers, allowing investments to follow the real progress of construction works.
Facing the growing difficulties encountered by young households in acquiring housing, HERITAGE will integrate an innovative measure designed to facilitate access to home ownership.
This initiative — a first in Luxembourg — will be revealed at the official launch of the project and aims to establish a new standard of inclusion and social responsibility in real estate development.

Between Route d’Arlon and Rue du Kiem, the first HERITAGE building will serve as a concrete demonstration of the standards upheld by the project. This 1,500 m² “Signature” building will combine high energy performance, optimised layouts, contemporary design, carefully designed shared spaces, and harmonious landscape integration. This first milestone, conceived as a true statement of quality, will set the tone for the entire development and embody the ambitions of the project.
HERITAGE reflects our conviction that it is still possible to build differently in Luxembourg — by combining architectural ambition, social responsibility, and construction excellence. This project marks a new step in our commitment to shaping neighbourhoods that genuinely improve the quality of life for residents.
Through KIEM and GAASCHTBIERG, the team behind Les Jardins de Luxembourg reaffirms its ability to carry out large-scale, human, and sustainable projects.
HERITAGE represents both the legacy of a know-how mastered over two decades and the desire to build differently, with responsibility and vision, the Luxembourg of tomorrow.
Marketing has already begun, with priority given to the sale of serviced plots for the construction of single-family homes, free of any building contract. All information on www.heritagebyjdl.lu
