Architectural description

As an existing building, the architectural concept has endeavored to conserve as much as possible all the elements that can be reused and reused to maintain a virtuous carbon footprint. In this continuity of idea, the project is conceived with a real adaptability on the medium and long term with much flexibility in its daily use but also a great resilience on the challenges to come.

The intervention focused on the use value of construction dedicated to an office assignment. Thus, the facades have been preserved largely in their structure and in the dimensioning of the wide open bays; The façades have been endowed with innovative elements such as a white external exterior cladding (external thermal insulation), pivoting frames on a vertical axis for reinforced domestic use, terraces cleared of any technical equipment allowing a real use, ... The light / day coefficient has been considerably increased in the low levels thanks to the brightness of the new white material, the working areas have been positioned only in direct lighting, allowing at the same time to offer horizontal and vertical Natural light. The large staircase shares with the 3 lifts an open common landing, naturally lighted which offers so many places of conviviality. The level on the first basement is also naturally illuminated either by glass floors for meeting rooms and restaurants, or by openings on the street side, or by the creation of a garden for the conference room .

The project gives pride of place to the contribution of natural light in the project which constitutes in all points of view to inscribe the project in a true environmental approach of common sense.
