The Cubex kitchen system, introduced in 1930, emerged as a modular, standardised solution that gained widespread adoption among the Belgian bourgeoisie. Developed by Louis Herman De Koninck, this functional innovation reflected his broader approach to design, which synthesised modern spatial concepts with a deep understanding of local architectural traditions observed along the Belgian coastline.
Early Career and Modernist Foundations
Active during the 1920s, De Koninck established his reputation through a series of residential projects that challenged contemporary conventions. His own house, completed in 1924, preceded his participation in the 1929 Congrès International d'Architecture Moderne (CIAM). The Lenglet House, finished in 1926, demonstrated a distinct departure from doctrinaire functionalism. Unlike the prevailing European trends of the period, his work avoided rigid adherence to the De Stijl movement, instead utilizing light and volume to create original spatial expressions.

Throughout the 1930s, De Koninck continued to produce significant residential structures across Brussels and beyond. He designed the Philippe Dotremont House in 1932 for a private art collector, a project that remains preserved in its initial state. Subsequent works included the 1934 Villa Nisot and various commissions such as the 1936 Villa Berteaux, which showcased advanced frontage compositions. His practice extended to institutional and multi-unit projects, including a group of flats and houses at Coghen Square, as well as the later 1968 apartment building located on Avenue Louise.
Archival Legacy and Historical Recognition
Upon his death in 1984 in Uccle, De Koninck left a comprehensive archive to the Archives d'Architecture Moderne in Brussels. This collection, containing blueprints, sketches, and professional correspondence, enabled detailed retrospective studies of his career. His work has since been positioned alongside contemporaries such as Rudolf Schindler. Critical examinations, including those by Dennis Sharp, have highlighted the divergence between his approach and the rigid functionalist models favored by other architects of the era.
