This extraordinary residence in Paris’ 16th arrondissement was built by Henri Deglane, the same architect that designed the Grand Palais. Not renovated since the 80s, designer Bryan O’Sullivan adapted it to 21st century living. He brought back elements that were previously removed, and enlisted many French artisans to restore plasterwork, millwork, and metalwork. Its grandeur and elegance is exquisite and the modern touches like Pierre Paulin sofas and Faye Toogood roly poly chairs create a wonderful juxtaposition to the classic architecture.
