An Architecture of Resonance
The new equestrian performance hall is situated within the Cour du Puits, one of the two
historic courtyards of the National Stud (Haras National). Rising seventeen meters high,
the edifice boldly redefines the site’s skyline. Its lofty silhouette soars above the
Napoleonic stables, echoing the vast slate roofs of these secular longères. In this history-
steeped, almost sacred context, we eschewed the anachronistic contemporary gesture.
«We summoned a classical vernacular to resonate with the soul of the place.»
Temporal Dialogue and Circassian Lexicon
The building’s skin engages in a temporal dialogue through delicately nuanced materiality.
The roof planes are clad in rectangular slates—vestiges of Napoleonic architecture—
interleaved with rounded slates of a more contemporary design. The molding of the slopes
becomes an architectural reinterpretation of the Circassian graphic lexicon. Through this
play of triangulation, the roof sheds its rigidity to evoke a sense of fantasy.
Perpetuating the Architecture of the Ephemeral
Inside, the timber frame unfolds into a spectacular vault, creating an interior landscape
whose structural power evokes the majesty of the Questembert hall. The project’s
archetype draws strength from the duality of early circus buildings: it borrows the stable
form of 19th- century sedentary circuses while inheriting the constructive intelligence of
«semi-stable» structures. The latter, designed for itinerancy, prioritized prefabrication and
rapid assembly. The constructive system is developed on a modular basis of three
templates duplicated fourfold: precision-machined structural elements, assembled on-site,
ensuring a fluid execution and a controlled construction footprint.
Scenography of Shadow and Light
The enchantment of the site extends beyond its exterior silhouette into the intimacy of the
interior volume. Our guiding principle was to design a structure that is discreet on the
facade but «mirifique» (wondrous) beneath the vault. Under the dimmed lights of the
scenography, the arched timber frame plunges the audience into a festive, fairground
atmosphere. To magnify this wooden «skeleton,» all secondary works and technical
systems adopt a dark, matte tone. This chiaroscuro treatment allows the envelope to
recede, highlighting the staged structure, whose light-streaked curves provide the intimate
ambiance required for artistic encounters.
Envelope of Timber and Light : Between Utility and Permanence
The facades encircling the Cour du Puits deploy a timber cladding with a rigorous grid,
offering the interior the image of a warm, protective heart. The cladding, composed of
horizontally crenelated wood panels, establishes a graphic dialogue with the lightness of
the louvers that close the roof tiers.
