Breeze Blocks: The Quintessential Component of Mid-Century Modern Design

Breeze blocks, also known as concrete screen blocks, are a type of brise soleil, which means "sun breaker" in French. They first appeared in the early 1900s as concrete manufacturing improved. The blocks were originally utilitarian - cheap, durable building units used for structural walls, basements, and industrial buildings. In the 1920s and 1930s, new technology led to experimenting with different moulds and patterns, which helped breeze blocks become the decorative features we know today.

These blocks quickly became an iconic, timeless element of mid-century modern design, hitting peak popularity between the 1940s and 70s. People loved how practical they were: letting in air and light. They were a brilliant, simple solution for brutal heat and glaring sun, offering shade and privacy all at once. By allowing air to flow through and casting cool patterns of shadow, breeze blocks help buildings "breathe." This was a turning point for reducing indoor temperatures in places like the American Southwest, California, Latin America, Australia, and parts of Africa and Asia, where airflow is everything. Their clean geometric designs fit perfectly with modernism’s obsession with repetition, modularity, and abstract shapes.

Breeze blocks do more than just keep you cool; they offer privacy without

making you feel boxed in. In desert environments, they’re perfect for blocking out dust and harsh glare while still letting you feel the outdoors. This "best of both worlds" approach draws on old-school desert design, think airy courtyards and filtered sunlight instead of airtight, sealed-off rooms. 

Design-wise, these blocks were the ultimate mid-century flex. Their geometric patterns were clean and modular but left plenty of room for play. Architects used them everywhere—from patios to stairwells—to erase the line between the living room and the backyard.

By the '70s, they hit a bit of a slump. As air conditioning and massive glass walls became the "it" thing, breeze blocks started looking a little dated and suburban. But they’re having a massive comeback right now. Today’s designers are rediscovering exactly why they worked in the first place: they’re tough, they look great, and they’re a genius way to cool a building naturally.

The Palm Springs area, the global capital of mid-century modern architecture, hosts a trio of amazing and committed groups focused on the past, present and future of breeze blocks: Ron & Barbara Marshall, Tesselle, LLC and the Palm Springs Preservation Foundation.

Ron and Barbara Marshall are award winning authors who wrote Concrete Sun Block – The Power of Pattern, a reference guide and history of breeze blocks.

Tesselle LLC, founded by Karin Jeske, is a leader in the design and manufacturing of breeze blocks and avid supporter of mid-century design and preservation.
