Gustave Strauven (Schaerbeek, 1878 - Haute Savoie, 1919) was a Belgian architect.His work of Maison Saint-Cyr is well known..It is his most important building built between 1901 and 1903 in a baroque-flamboyant style. It was built to be Georges de Saint-Cyr's private residence. It is four metres long and it has a good deal of wrought iron in the façade, which is adorned with geometric motifs and each balcony has a balustrade. The wrought iron mimics vegetation and the decorative elements occupy all the space available. Due to its extravagance, the building has been called Art Nouveau baroque. It is in a poor state of repair, and negotiations are taking place to secure the funding needed for its renovation.
