Breeze Blocks are a concrete decorative architectural feature popularized in the mid century used to block direct sunlight but allow airflow especially when air conditioning was less prevalant in southern climates. Their interesting patterns are featured in commerical applications on the front of a building or to enclosure a stairwell. In residential applications they are employed as a car port or built between homes as a screen to allow light but still define space and privacy as well as provided decoration. I fear they are fast disappearing here in South Florida. Below is an office building that removed its breeze block facade this past year. Shame.
