Interior design by OOO - Building architecture by Archipelago | BAEV

ORES headquarters, Gosselies Project

New Way of Working, symbol of the transformation of ORES

ORES is one of the main suppliers of electricity, natural gas and public energy distribution networks in Wallonia.

Change management
Development of the concept and implementation of the future ORES way of working.

Interior design
Macro and micro layout, made-to-measure furniture, mood boards, signage and choice of materials and furniture.

Budget estimation of the interior design & follow-up of interior work in collaboration with Archipelago – BAEV, architect and coordinator of the entire ORES project; GEI for stability and special techniques, MATRIciel for sustainable development and At Osborne for the control of delegated work.

The aim of the project was to bring together 1000 employees from various buildings spread throughout Wallonia into a single headquarters to facilitate exchanges as well as transversal collaboration. Moreover, the project had to implement a new work organization, more flexible and based on activity based working. 

From the start of the project, OOO Change Management team supported, stimulated and challenged ORES through participatory workshops, in order to define their future way of working. This methodology was then translated by the OOO Design team through an interior layout in which this new way of working could come to life. The interior architecture is at the service of the organization, the values, the culture and the strategies of ORES. Throughout the project, the two OOO teams worked hand in hand with the different ORES departments to improve the interior architecture (in collaboration with Archipelago – BAEV, At Osborne, MATRIciel and GEI), while familiarizing ORES teams with those new working methodologies.

The realization is a subtle mix of spaces favoring creativity, transversality, modularity, conviviality and well-being. A design that reflects the soul of ORES; natural and warm materials. The project is built around different areas for different types of activities, a large reception hall, a training center, a restaurant, a boardroom area, a space dedicated to sport and well-being, a platform, collaborative spaces, closed or semi-closed offices with common tables, a library, alcoves, meeting rooms, discussion areas.


Large and very complex project: construction of a new head office bringing together colleagues from all backgrounds and all trades. OOO helped us to understand the needs that were not met by the old premises and to develop an architectural program that best meets them, in collaboration with the BAEV Architecture Office (Archipelago). Adaptability of interior spaces, well-being, attention to people and harmony were the main challenges of this project, while respecting budgetary constraints. Having the right workspace for the execution of a task, its duration and its nature has now become possible and infuses a new dynamic that is more agile, more responsive. This new building is a space for work and convergence, which takes ORES to a new world of work, a more open environment where flexibility, mobility, meetings and exchanges stimulate ORES’s creativity and very activity.
