5 Striking Designs That Use Perforated Cement Breeze-Blocks in Interesting Ways

Architecture 30-8-2017 DWell 1670

Breeze-blocks, perforated concrete blocks, cinder blocks, cobogó, or even decorative terra-cotta bricks: call them what you will, but these patterned hollow blocks have an unforgettable visual impact and a far-reaching ability to provide shade, sunlight, structural support, and privacy.

Natural light floods the space from both sides

Patterned concrete block may have originally been introduced in the late-1920s in Brazil, but today, it can be found in warm-weather areas across the world. Indeed, when it was first invented by a team of Brazilian engineers (who called it cobogó: a combination of their own initials), it was seen as an appropriate local building material that allowed light and air to pass through while still providing some shade and privacy. 

By the 1950s and 1960s, the use of patterned, hollow concrete block had spread to other warm-weather areas around the globe that could benefit from its dappled light and wide variety of patterns, sizes, colors, and eventually materials. Today, breeze blocks are being reintroduced in a variety of projects not only for their aesthetic properties, but also for their contributions to sustainable architecture and their ability to permit cross-ventilation and the possibility of using recycled materials. Here, we take a look at some intriguing examples of architectural screen blocks around the world.

Poolside Perforated Brick in Brazil by Figueroa Arq

Located in São Paulo, Brazil, this serene outdoor space is part of the Aigai Spa, which was designed by figueroa.arq, but it could just as easily be someone’s home. The elongated pool runs the length of the patio and at one end hangs a multicolored swinging chair.

The use of the two types of concrete continues throughout the project, both on the interior and the exterior spaces.

A pool is still the focal point of the courtyard, but its modernized, streamlined design makes a dramatic statement.

At what was formerly a run-down motel from the 1970s in Mexico City's central Cuauhtémoc neighborhood, JSa Arquitectura gave the 36-room hotel a fresh face. The interior courtyard, with a revamped, glass-edged pool, is framed by rectangular, hollow concrete bricks.

Today, as in the 1970s, the central courtyard is an oasis within the city. Along with a pool, the area is also home to a market-centric restaurant.

Block It OutSeeking an inexpensive way to create a screen effect between the bathroom and bedroom, Novak-Zemplinski and Nix hit on the idea of stacked open-cell concrete blocks, more typically used in parking areas. They discovered blocks with a more-interesting-than-average pattern in Chyżne, a town near Kraków. Better still, they cost just two dollars each. “When we saw how good these parking blocks looked in the bedroom, we thought they’d be a good way to hide clutter in the kitchen, too,” says Novak-Zemplinski.

Ornate concrete blocks screen a storage area in the kitchen while letting light through. The effect is “romantic—romantyczny,” says Nix.

The hollow concrete blocks screen a storage area in the kitchen, but permit the passage of light. The unusual pattern was found at a town near Kraków at a cost of just two dollars each. The blocks add a strong visual and textural component to the space, as well as the functional element of privacy.
