De Ultieme Hallucinatie

A. de Ville de Goyet ©

This neoclassical town house, built in 1841, was completely transformed in 1904 by architect Paul Hamesse in the geometric Art Nouveau style. In consultation with his clients, the Cohn-Donnay family, he filled the house with handsome furniture that perfectly matched the decor. The Vienna Secession and Greek Revival styles are very much in evidence in the front drawing room, with its impressive marble fireplace and its frieze depicting dancing women, while the influence of Scottish architect Charles Rennie Mackintosh is visible in the stylised floral motifs and white-painted woodwork of the small central sitting room.Also noteworthy are the chess game room and its stained-glass skylight, the large hallway with its mosaic floor and walls painted with insects, the billiard room and the stylised trees adorning its walls, and the stained-glass door separating the billiard room from the dining room, where the elegant peacock motif seen on the door is echoed on the ceiling, along with flowered umbels. On the façade, the original balcony has been incorporated into a projecting wooden oriel in the Art Nouveau style. Today, this oriel is inscribed with the name of the bar/restaurant that took over the building in late 1981: De Ultieme Hallucinatie. (Listed 08/08/1988)

The EDEN 2.023 photography exhibition, produced by photographer Violaine Alghisi, lends unique expression to both the architectural dimension of bodies and the organic corporeality of Art Nouveau architecture.
