The living room features an Equation sofa and Bi-Pod stool, both from Roche Bobois, atop a 1970s Siberian wolf carpet. Through online sleuthing, Roche found the red Boris Tabacoff chair at an Austrian gallery. The chandelier is vintage. Roche’s most-recent acquisitions include the traditional African masks, which he likes for their “aesthetic purity, the beauty of their forms.”
