If interior designers invariably use their home as a workshop for their ideas, having two interior designers under one roof only amplifies that. After five years, Orsini Daventure’s Clement Daventure and Clemence Orsini had exhausted the possibilities of their Haussmann-style apartment in Montmartre and were ready for a new challenge. Fortuitously, Daventure stumbled across the listing for a two-bedroom space in a 1970s-era building not far from where they were living.Clement Daventure (left) and Clemence Orsini in their Paris apartment “It hadn’t been touched in 55 years,” Orsini recalls. But the layout was ideal, the light was beautiful, and the view over the building’s private park was serene. Having sold almost everything in their old home to its new owners, they would be starting from scratch in rooms that were devoid of the architectural details that had distinguished their old space. “So there was nothing to hold us back from expressing ourselves,” Orsini shares.The couple, who met during their last year at École Camondo, Paris’s prestigious school of product design and interior architecture, had taken very different career paths before deciding to join forces five years ago. Daventure’s classic sensibilities were honed while working for Franz Potisek, where the idea of traditional extended to eschewing computer-generated schematics in favor of hand-drawn plans. In contrast, Orsini was steeped in minimalism and clean lines through her work with Studio KO. Their divergent paths intersect over a love of Italy, exquisite decorative details, rich materials, and the color green.In the entryway, Manuel Canovas’s Nura fabric tops a baseboard created from ribbed travertine and floors of stained oak from Carrésol. Curtains created from Casa Lopez’s Coup de Chance textile showcase a terra-cotta bust of Agrippa, purchased from Vermot & Associés auction house, which tops a plinth created from wood swathed in green suede with an aragonite top, designed by Orsini Daventure. The 1980s-era wood chair, designed by Christian Gratia, was found at Maison Pline auction house.
