Didier Van Den Eynde

Agora, the territorial agency in charge of reconverting Belval, one of the former Arcelor steel industry brownfields of Luxembourg, has undertaken a call for tenders for developing part of the new ‘Square Mile’ district. BPI and Unibra real estate developers, in collaboration with the architectural firm ArtBuild Architects, have been selected as the winning team of the competition for lot 41 of the masterplan developed by KCAP town planners. The deed of sale for this plot of land will be signed no later than 30th June 2021.

The project on lot 41, branded ‘The Roots’ consists of four buildings with a total surface area of almost 20,000 m2; one of 7,000 m² of office space, the other three for a mix of 2,000 m² of retail at ground floor level, and 10,600 m² of housing (94 accommodation units). The buildings will be built above an underground 260-space car park. Work is set to begin in the second half of 2022 for the project to be completed in 2024.


The circular economy and an environmentally friendly approach are the main drivers behind the project. All buildings will be constructed in wood, with the expertise of both ArtBuild Architects and Wood shapers. The developers of ‘The Roots aims the project to be triple certified Breeam, Well and BBCA (Low Carbon Building). ArtBuild has a wealth of experience in timber construction projects and Wood Shapers – a subsidiary of CFE – is currently collaborating with developers BPI Real Estate and IKO Real estate for the building ( for insurance company La Bâloise), the first large all wood office building in Luxembourg (9.600 m2).

Following the Glesener 21 project in Luxembourg and Gravity in Differdange, BPI Real Estate and Unibra Real Estate are reinforcing their collaboration through this project and positioning themselves as leading developers in environmentally friendly projects and as key players in Luxembourg.
