The CNP-NPM headquarters are built on an exceptional site bordering a vast protected forest close to the N5 road Charleroi-Philippeville.

The building is oriented so as to face the cardinal points. Besides the company’s executive offices, the building contains several reception areas and conference rooms, as it serves as a meeting place for all the companies of the CNP group.

All functions are structured around a vast inner courtyard facing south. The courtyard, two levels high, occasionally serves as a concert hall. Above it are dining and reception rooms with related facilities.

The northern part of the headquarters contains, on the ground level, large meeting rooms and a library, and on the second floor, the president’s offices. The third floor is an executive apartment.

The ground and second levels of the east and west wings are reserved for management offices.

The overall composition is simple and classical, and sits on a park landscaped to relate to the four cardinal points. Inside the building, the demand for calm and serenity, the wish to integrate large works of art and to provide an environment of physiological comfort (natural lighting and ventilation, odour and acoustic control) command very high ceilings.

The simplicity of the interior design (white walls, wooden floors) is echoed by the facade with both clear and white crystal glass. Horizontal glass roofs separate the four main building parts (the courtyard, the president’s offices and the two other office areas) in order to distribute natural lighting to the centre of the building and right into its corridors.
