Explore.Brussels can arrange guided tours for your group of one or more of five Art Nouveau buildings that are not usually open to the public. These buildings are the Max Hallet House, the Solvay House, the Van Eetvelde House and the Autrique House (all by Victor Horta) and the house which architect Paul Cauchie designed for himself. These guided tours will allow your group to go right to the heart of this architectural style that started at the end of the 19th century, so they can judge for themselves whether or not Brussels deserves the title of Capital of Art Nouveau. Guided tours are also available of other Art Nouveau and Art Deco buildings in Brussels on request. For the five buildings mentioned above, the prices and maximum group sizes for a one-hour guided tour are: Max Hallet House, €500, 25 people maximum; Solvay House, €825, 22 people maximum; Van Eetvelde House, €300, 15 people maximum; Autrique House, €250, 25 people maximum; Cauchie House, €225, 15 people maximum.
