In 2008, Kayrouz returned to Paris to open his own design house at 38, Boulevard Raspail. The location was previously "Le Petit Theatre de Babylone" where Beckett's play Waiting for Godot was performed for the first time . Since 2009, Kayrouz has been a guest designer for the Chambre Syndicale de la Haute Couture, with his seasonal collections included in the bi-annual Parishaute-couture fashion shows. In 2011, Kayrouz was selected by the prominent French ELLE Magazine as one of the "Emerging New Talents". In 2012 he abandoned the appellation "couture" to focus on ready-to-wear. In the same year, he created a capsule collection for La Redoute (French mail order brand).
