1st Stone Laid for New PwC Campus in Cloche d’Or

On Friday 25 April 2025, Cloche d’Or Development, together with Atenor as developer and PwC Luxembourg as future tenant, announced the ceremonial laying of the first stone for a new “state-of-the-art” building in the heart of Cloche d’Or.

The ceremony took place in the presence of Lydie Polfer, Mayor of the City of Luxembourg, Stéphan Sonneville, CEO of Atenor, Stefano Moreno, Founder of Moreno, Sebastian Moreno, Founder of A2M, and François Mousel, Managing Partner of PwC Luxembourg.

According to PwC, this first stone ceremony marked not only the beginning of an exciting new chapter for PwC Luxembourg but also a reaffirmation of its pioneering spirit that first took root in the district more than a quarter of a century ago.

PwC Luxembourg established a presence in Cloche d’Or as early as 1999, at a time when the area was still under development. In 2014, the company relocated to Crystal Park, one of the first new-generation office buildings on the Ban de Gasperich, contributing to the early development of what is now the Cloche d’Or business district.

Following the recent ceremony for the laying of the first stone, the new PwC Campus is said to mark a continuation of the firm's development in Cloche d’Or. The project is being developed by real estate firm Atenor, bringing expertise in sustainable and human-centred urban development.

The new building has been designed with a focus on future-oriented architecture, energy efficiency and the well-being of its occupants. It will include centralised client reception areas across two dedicated floors, with the top floor featuring a terrace intended to offer an enhanced visitor experience. The design will integrate access to green spaces, open-air areas and wellness-oriented features, reflecting evolving approaches to workplace environments. The building aims to support new ways of working and interaction while aligning with broader sustainability goals.

Cloche d'Or Development entrusted the construction project to a temporary joint venture composed of CBL, CLE and Galère Lux. Construction is set to be completed by April 2027, with 34,500 m2 of offices and offers a variety of features designed for collaboration, sustainability and technological integration.

PwC added that the project integrates advanced sustainability standards from the ground up:
- BREEAM outstanding and Well platinum certification targeted, ensuring environmental excellence and occupant well-being;
- four buildings, 4,000 m2 of green roofs and terraces to enhance biodiversity and reduce heat island effect, fostering openness to the outside and a closer connection to nature;
- intelligent energy systems to lower carbon footprint and maximise energy efficiency;
- high-performance insulation, smart lighting and solar panels on all roofs reducing consumption up to 70% in comparison to Crystal Park;
- multimodal accessibility, close to public transportation, with bicycle facilities and electric vehicle charging stations to promote soft mobility.

The building has been designed not just as a place of work, but as a responsible and inclusive space in harmony with the values of the City of Luxembourg — supporting both the economic vitality and environmental goals of the Cloche d’Or district, according to the PwC statement.

François Mousel, Managing Partner at PwC Luxembourg, said: “Back in 1999, when Cloche d’Or was still undeveloped, we saw opportunity where others saw uncertainty. Despite the challenges, we chose to stay, invest and grow with the neighbourhood—long before it became the vibrant district it is currently. Today, we build on that vision. This new building embodies our ambition to create not only a workplace but a long-lasting presence in the heart of a forward-thinking district. […] In short, it represents who we project to be as a team for our clients and stakeholders.”

“We are deeply proud to continue our journey in Cloche d’Or — a district where vision, urban planning and sustainability converge. Our roots are here. This new building represents our investment in a greener, more connected future, and we are honoured to do so hand-in-hand with the City of Luxembourg, whose leadership has made such progress possible,” stated Dominique Laurent, Managing Director, Head of Administration and Logistics at PwC Luxembourg.

Stéphan Sonneville, CEO of Atenor, commented: “Campus reaffirms Atenor’s dedication to Luxembourg's sustainable real estate landscape, delivering exceptional value while enhancing the urban fabric of vibrant districts like Cloche d'Or. This flagship development perfectly embodies the group's commitment to placing people and the environment at the heart of its urban development strategy. An approach that has guided our 25-year presence in Luxembourg, confirming the operational expertise and technical know-how of the local team in delivering future-ready urban solutions.”
