Architectural design competition

As part of the project to transform and repurpose the site of the Old Slaughterhouse in Hollerich – also known as the "Schluechthaus" – the City of Luxembourg hosted an open day at the site in September 2019. On that occasion, the City collected a number of proposals put forward by local residents. In 2021, following on from that event, the City drew up an urban and architectural planning programme for the 2.5-hectare site. To preserve the site's strong architectural identity and urban artwork, whilst also creating a space dedicated to cultural creation and urban sports, the City launched a European architecture competition in August 2022.

To select the architectural project(s) most suited to the requirements set out in the project specifications, the competition will be run in two phases. Further to the call for applications (the first phase of the competition), six teams were recently selected to take part in the European architecture competition (the second phase of the competition).

Purpose of the competition

Through this project, the City wishes to reaffirm its commitment to revitalising the Schluechthaus site, which boasts an excellent location in the southern part of Luxembourg City, near major thoroughfares, several schools and the future "Porte de Hollerich" eco-district. Accordingly, for the site in question, the City wishes to:

  • provide an intergenerational and inclusive gathering place;
  • develop cultural happenings and activities hosted by associations;
  • maintain and develop the range of indoor urban sports activities on offer at the site, to complement the outdoor facilities in the Pétrusse Valley;
  • promote and perpetuate street art;
  • enhance the existing and protected built heritage;
  • connect the surrounding districts – both existing and future ones – by creating a genuine urban space (hybrid park);
  • serve as a model of eco-friendly development through the choices made for this project.

In the City of Luxembourg's search for a pioneering, iconic project that reflects the urban planning specifications and regulations, while at the same time meeting the expectations and challenges that have been identified, the City of Luxembourg is also looking for a partner who will be able to leverage its vision and network to develop and grow the project, in order to realise its full potential by bringing the Schluechthaus site to life.

Members of the panel of judges

The panel of judges will consist of representatives from the City of Luxembourg, the consultancy firm, the National Centre of Industrial Culture (CNCI), the National Institute for Cultural Heritage (INPA), the Order of Architects and Consulting Engineers (OAI) and three international experts.
