Hamburg, Germany, is pioneering the world’s first algae-powered building, a revolutionary step toward sustainable urban living. This innovative structure will rely entirely on renewable energy microalgae to provide hot water, lighting, heating, and power. According to the architects behind the project, future buildings should not just be constructed—they should be "born" with biological traits, capable of responding to their environment and interacting with residents like living organisms.
While this vision is impressive, London-based design studio Loop pH believes there's more to explore. They argue that future architects must not only understand science but also art. Inspired by the molecular bonds in biological structures, Loop pH designed the “SOL Dome,†a unique lighting art museum that blends architecture, science, and aesthetics.
The SOL Dome is a lightweight, solar-powered structure made from composite fibers that change brightness and color based on carbon dioxide levels. Its most remarkable feature is its extreme lightness—each 8-meter-long, 4-meter-wide panel weighs just 40 kg, making it the lightest house in the world. To assemble the structure, these fibers are woven into circular rings and connected to form a honeycomb-like home.
At the “Fall In Art and Sol†solar festival in Fall, USA, the Loop pH team and volunteers built the entire house in just three days. The dome is equipped with LED fiber optic rings that act like batteries at night, glowing with dynamic colors. Each ring responds to environmental changes, creating an ever-evolving visual experience.
The artistic concept of the SOL Dome is “taking it natural and sensing nature.†By integrating LED elements and CO2 sensors, the structure reacts to the surrounding air quality, shifting colors and rhythms in real time. As sunlight and CO2 levels fluctuate, the dome transforms, mimicking the breath of a living being. At night, as CO2 concentrations rise, the colors deepen, giving the illusion that the building is breathing.
Loop pH sees the SOL Dome as a foundation for future architecture. They envision homes that adapt to their surroundings like organisms, blending cutting-edge biology and public energy research. Their goal is to bring such art into city parks, allowing people to engage with scientific progress and connect more deeply with nature.
Garne Ulm, who leads the development of algae-powered buildings, shares this vision. With the global population expected to reach 9 billion by 2050, and 75% living in cities, the need for sustainable solutions is urgent. Future buildings will integrate green spaces, water recycling systems, and intelligent networks to manage urban environments effectively.
Since 2003, Loop pH has worked on projects that merge science, design, and community needs, from neighborhood revitalization to palace renovations. Their mission is to create living spaces that protect people while inspiring reflection on nature and the cosmos.
As humans seek to transcend limitations, just as birds fly, we too aim to return to nature and find sustainable development. Future architecture won’t just mimic nature—it will learn from it, creating smarter, more responsive, and truly living buildings.
