Hotel Haerens, Art Deco residence in Uccle, Belgium.

Hotel Haerens is a Art Deco master's house built by architect Antoine Courtens at 384 avenue Brugmann, on the corner with rue de la Ramée in Uccle. Its pale cream stone facade is broken into stepped volumes: an entrance bay with a rounded porch flanked by two fluted columns and a hammered wrought-iron door, a slightly projecting central section with three rectangular windows per level, and a rotunda that follows the angle of the two avenues, pierced by four windows per level and topped by an extra storey with a copper dome. The Brugmann facade also carries an oriel above the porch; the rue de la Ramée side repeats entrance bays, an oriel, a garage door and a projecting triplet of windows with a loggia.

The building was commissioned in 1928 by engineer Robert Haerens and designed by architect Antoine Courtens, drawing influence from American architectural traditions. The original structure with separate living quarters and distinct entrances was later converted into office spaces and underwent major restoration work in 2009.

The attic frieze above the cornices of the facades and the rotunda carries geometric ornaments resembling those Frank Lloyd Wright used at Unity Temple in Oak Park (1905) and Hollyhock House in East Hollywood (1917). Courtens encountered Wright's work through Victor Horta, in whose studio he trained in 1924, and through the 1925 illustrated issues of the Dutch review Wendingen.

The building is now divided into office spaces and not open to general visitors. The exterior is visible from the street, allowing you to appreciate the Art Deco architecture and details from outside.

The attic frieze above the cornices of the facades and the rotunda carries geometric ornaments modelled on those Frank Lloyd Wright used at Unity Temple in Oak Park (1905) and Hollyhock House (1917). Courtens adopted them from 1928, after Horta's studio introduced him to Wright's work.
