7-9 Curtin Avenue
Private residential property. View from the public footpath.
Bulgarian-born Iwan Iwanoff arrived in Perth in 1950 and developed an architectural language particularly suited to WA's light and climate. His houses became known for bold geometry, deep shade and extraordinary decorative concrete blockwork - using ordinary masonry not just to build walls, but to create pattern, texture and constantly changing shadows.
Built in 1983, the Gelencser House at 7-9 Curtin Avenue is one of Iwanoff's later works. The long, repeated facade gives the building an almost monumental presence: heavy masonry piers and projecting balconies sit beside large areas of glass, while individual blocks step forward and back to create intricate patterns across the concrete surface.
The Town of Cottesloe's heritage inventory describes the building as an "outstanding example of architecture by one of Perth's most talented architects - Iwanoff". It remains private residential property, so stay on the public footpath, but take a moment to look across the whole facade and then at the individual blocks - the closer you look, the less ordinary they become.
