For the apartment of the artist Camille Henrot and composer Mauro Hertig, designed by Husband Wife, CHH was brought in for interventions within the living room and bedroom of the couple's two sons. Working with the artist Elissa Medina, the fireplace mantel and shelving were clad with custom grotto tiles inspired by the fireplace Robert Winthrop Chanler designed for Gertrude Vanderbilt Whitney in 1917. In the sons' room, the wooden door frame is an homage to the lightless, soundless cave of Hypnos, the Greek god of sleep. Soporific plants, like poppies, mandrake, and valerian frame the verdant entrance to the cave, from which the River Lethe runs. Spanning the headboards is a passage from a well known Swiss German lullaby selected by Mauro - when translated, it reads, "... and from it comes a rainbow, and all that hurts has vanished."
