Businessman J. Simonis built this building for the Koninckx brothers during the 1910’s. In the beginning, it was an apartment building with separated leasing of commercial units on the ground floor and apartments on the floors above. It boasts an impressive size and symmetrical composition, with a façade that combines elements of different styles. The triangular pediments on the dormer windows and the cornice with indentations are classical patterns. However, many details have been taken from the decorative repertoire of Art Nouveau: metal guard rails in the shape of insects, stones in organic shapes on the balcony above the entrance, with sculpted leaves at the base of the frame and symbolistic faces at the tops of the pilasters (a genuine fashion form the era that we will often come across on this circuit). The chassis were replaced with identical elements in 2010.
