This two-bedroom Paris apartment is located in Neuilly-sur-Seine, a tranquil residential area just outside the city. Its owner, a native Parisian, didn’t seek out its quietude just as a retreat from the city noise – he also knew it would be ideal for enjoying music, his personal passion. “His love for vinyl records, sculptural furniture and raw materials was a key part of his brief to us,” says Esther Katz, who runs Paris-based Katz Studio with her sister Leah. The duo is known for its intimate, timelessly elegant spaces, and transformed this residence in a late-20th-century building into the tailor-made sanctuary you see here.
