Dutch engineers are transforming ordinary buildings into vibrant, living green ecosystems. According to recent reports from the Netherlands, researchers have developed innovative “living bricks” that support the growth of natural algae, turning walls into stunning vertical gardens that help combat urban pollution and climate change.
Bricks that absorb carbon dioxide
These algae-covered bricks act as natural air filters, absorbing carbon dioxide and other airborne pollutants, thereby purifying the surrounding air. Since algae retain moisture and thrive in humid environments, they also help cool buildings by reducing heat absorption. In turn, this makes cities cooler during increasingly frequent and intense heatwaves.

The living bricks were engineered to be self-sustaining, requiring no fertilizers, irrigation systems, or intensive care. They rely solely on natural rainwater and ambient humidity to support their growth. Their low-maintenance nature makes them particularly well-suited for urban environments, according to One Green Planet.
Algae brick production projects
Pilot projects using algae bricks are currently underway in schools and residential complexes across the Netherlands. If these living façades are implemented on a large scale, they could help cities reduce emissions, improve air quality, and make urban spaces more livable—while also enhancing their visual appeal.
Climate solutions don’t have to be costly
This type of bio-based innovation demonstrates that climate solutions don’t have to be high-tech or expensive—they can be as simple and effective as harnessing the power of nature.
If we want greener cities and cleaner air, we must rethink our construction methods and support natural solutions such as living bricks.
The next phase of construction in the UK
In the United Kingdom, Brenda Parker from University College London and her colleague, architect and professor of innovative environments Marcus Cruz, state that the next stage is “engineered living materials.” These are materials in which biological components remain alive after installation and respond to their surroundings, or are simply designed to attract living organisms, according to The Guardian.
Straw houses in Australia
In Australia, straw—a traditional building material in other continents—is slowly finding a market. Seventy homes have been built using straw bales, and another forty-one with straw panels. These prefabricated panels come with various finishing options, including plaster or plywood. The coated panels have undergone fire-resistance testing by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and are approved for construction in areas classified as highly prone to bushfires.
