This “residence for a rich collector” was a great success and led to a stream of commissions, not only from public institutions such as the Palais de l’Elysée, the Union central des arts décoratifs and the Metropolitan Museum in New York, but also from private individuals. These rich industrialists and art lovers included the British press magnate Lord Rothermere (owner of the "Daily Mail" and "Daily Mirror"), who wished to furnish and decorate his apartment on the Champs-Élysées.

A decorator and interior designer, Ruhlmann conceived the combined sitting and dining room as a total work of art exemplifying the elegance and modernity of his style, where each detail of the woodwork, sculpture, metalwork, lighting and furniture has its own importance. The play of light from the windows, the bow window and the light fittings sets off the elements of Indian rosewood, whose dark colour is enlivened by the veins and ten metopes sculpted by Louis Pierre Rigal on the upper frieze. From the door handles to the hinge covers of silver- and chrome-plated bronze, the moldings of the cornices and the borders of the door panels, everything contributes to the luxurious harmony of the room.
