Antoine Varlet was, with Michel Polak and Sta Jasinski [fr], one of the pioneers of apartment building construction in Brussels.

His name appeared for the first time in the Brussels landscape in 1923 for an industrial complex at 42, rue de la Gare/Stationstraat in Etterbeek,[3] in collaboration with his brother, the architect Walthère Varlet.

[6] Varlet was a follower, like his colleague Pierre De Groef [fr], of the Beaux-Arts style in the middle of the Art Deco era.

His specialty was makings buildings at street corners which give a wider perspective, a practice which has served as a precedent for many architects in Brussels since then.

[7] Starting in 1929, his style became influenced by the then dominant Art Deco style, while still keeping many Beaux-Arts elements in his works: red or orange brick facades, bordered with white stones, forged iron doors, decorative low and high reliefs, which help mitigate a coldness that is sometimes found in Art Deco buildings.
