Built in 1907 by the architects Constant Bosmans and Henri Vandeveld for Émile Waxweiler (1867-1916), director of the Solvay Institute of Sociology, the house was decorated the following year, both the facade and the interior, in a geometric Art Nouveau style by the architect Léon Sneyers. Its purified design, its furnishings and modest decor, reminiscent of the Vienna Secession, all contribute to making it a unique work of art that has been magnificently preserved and restored.
