Integrating algae along its timber facade, this urban structure enhances air quality and promotes sustainability while serving as a refuge for residents in a densely populated environment.
5 key facts about this project
01
Algae on the facade actively filters air, improving indoor air quality.
02
Timber serves as a carbon capture tool, enhancing sustainability.
03
Design includes trees that can be sustainably harvested at the end of their life.
04
Vertical farms and composting areas create a functional circular ecosystem.
05
Building adapts to provide refuge during environmental crises like smog.

Algaescape is located in Delhi, India, and aims to address the serious air quality issues the city faces. The building is designed as a self-sufficient structure, focusing on sustainability and resilience. Its overall concept is to improve living conditions while also benefiting the surrounding environment through natural processes.

Air Purification System

The design features an innovative air purification system using algae placed along the building’s facade. These algae act as a natural filter, absorbing carbon dioxide and releasing oxygen through photosynthesis. This interaction between the building and the algae enhances indoor air quality and supports a healthier urban ecosystem.



Material Integration

Material choice plays an important role in the project, with timber being a key element for both its functional and visual aspects. Timber captures carbon, aligning with the goals of sustainability. Additionally, trees incorporated into the design sequester carbon throughout their growth, and these can be sustainably harvested at the end of their lifespan. This process promotes a closed-loop system, helping to reduce waste.



Ecosystem Features

The building also includes vertical farms, biorefineries, and composting areas. These features create a circular ecosystem dedicated to food production and efficient waste management. They not only enhance the building's functionality but also encourage residents to engage with their environment in a more meaningful way.



Adaptable Refuge

Algaescape is designed to adapt to various needs, providing a safe space during environmental crises such as severe smog or smoke. Different areas within the building can be repurposed quickly for shelter, ensuring that occupants remain safe. This approach fosters self-sufficiency, allowing residents to access clean air, food, water, and energy.


The facade is characterized by a distinctive arrangement of the algae panels, creating a textured appearance that contributes to the building's environmental mission while establishing a unique presence in the urban landscape.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
