Reluctantly being put on sale, the owners have been lovingly restored over the years this unique duplex apartment to bring out its historical value and also selected, with minute attention to detail, various beautiful items (precious chandeliers, lamps, furniture and other decorative masterpieces in wood, glass and bronze) from this short-loved period. Constituting a landmark in Parisian architecture, the building itself, projected and built by the famous architect Jules Lavirotte in 1907, epitomises the continuity of an international style, successfully embodied in magnificent urban examples, from Paris to Brussels, from Prague to Barcelona, from London to Vienna. With volumes of up to 6 m, surrounded by superb bookcases, the extraordinary living-room with its enormous dramatic window open on the trees of the elegant Avenue de Messine commands your attention and leads to a world of another era. Comfortably and cosily furnished despite the palatial volumes of the main room, the property benefits from a beautiful small dining room in the form of an Art Nouveau 'cabinet', giving a true feeling of intimacy and other worldliness. On the same level, a kitchen, a guest toilet, one exquisite bedroom and its bathroom, both decorated in the coherent and beautiful style of the apartment and a rear balcony allowing to explore the inner courtyard of the historical building. A sweeping marble staircase in the entrance hall, sided by walls elegantly painted with frescoes, leads to the upper floor, where a dramatic and unusual balcony area, reminiscent of a theater scene, dominates the downstairs salon. The master bedroom, with its adjoining curved bathroom, his and her showers as well as a freestanding bath and dressing rooms, is independent from the lower level and constitutes a sort of large intimate alcove. Not to be forgotten is the grand circular entrance of the building, which leads to a beautiful staircase featuring exceptional metalwork from the period on the doorways and elevator. A large cellar completes this unique and unrepeatable Parisian property.
