a natural machine
The new headquarters of the Ministry of Defense on the Balard site is designed as a natural machine that is energy self-sufficient 80% of the time. It is characterized by a facade alternating transparency and opacity, buildings on stilts distributed around patios, a vast tilted roof in metal sections, and energy performance far beyond the most recent regulations. The Balard project brings together in one place the staffs – EMA, EMAT, EMM, EMAA – currently spread over three separate sites.
a discreet fortification
It is a composite building, regal and monumental, but also discreet and stealthy. Its exterior facade forms a long white enclosure arranged in layers. They convey complexity and serenity, the core of a thought that works to preserve the balance of the world.
Like a cliff, white materials alternate in horizontal layers: from more or less transparent screen-printed glass to more or less opaque, shiny and matte glass-ceramic. This monumental facade is alive, vibrates with light, protects the ministry and secures its interior.
On the ring road, this facade disappears because the building has gradually tilted, and can only show its roof.
This roof is a large unusual topography in the Parisian landscape, a stealthy architecture composed of metal sections assembled as in an origami and three chimneys symbolizing the three army corps joined together. The whole forms a dynamic geometry that wraps around a heart, the Hexagon, place of high authorities and the operational hub.
