Constructed with thermochromic water goblets and drop-stitch construction, the vertical algae cultivation system demonstrates an efficient approach to sustainable biomass production.
5 key facts about this project
01
Constructed with thermochromic surface coating to regulate temperature and enhance energy efficiency.
02
Incorporates eight water goblets designed for effective rainwater collection and algae cultivation.
03
Utilizes drop-stitch construction for lightweight structural integrity and flexibility.
04
Features a nutrient supply system for optimal absorption of essential salts and CO2.
05
Designed specifically for vertical cultivation, maximizing sunlight exposure and space utilization.

The project focuses on vertical algae cultivation, designed to promote sustainability and efficiency in biomass production. Located in an environment favorable for algae growth, the design makes use of natural resources, including sunlight and rainwater. The concept blends modern agricultural techniques with responsible architecture, providing a practical approach to energy generation.

Vertical Cultivation System

At the core of the structure is a vertical cultivation system that optimizes space and maximizes sunlight access, which is essential for photosynthesis. This design allows for significant biomass production, supporting the harvesting of alternative energy sources. The layout emphasizes efficiency and streamlining the processes involved in growing and collecting algae.

Water Goblets

The project features eight water goblets specifically designed for rainwater collection, accumulating a total of 29,780,000 m³. These elements are important for reducing reliance on external water supplies, contributing to a self-sustaining cultivation environment. Their careful placement within the overall design enhances not only functionality but also aligns with the project's ecological goals.

Nutrient Supply System

A comprehensive nutrient supply system is integrated into the architecture, allowing for the absorption of essential nutrient salts and carbon dioxide, crucial for optimal algae growth. This approach ensures the healthy development of algae, supporting efficient production cycles. These integrated systems demonstrate an understanding of the complexities of cultivating marine biomass.

Advanced Materials

Advanced materials are employed to improve the ecological performance of the design. The thermochromic surface coating adjusts to temperature changes, enhancing energy efficiency. Drop-stitch construction techniques are used, providing strength and reducing weight in the structural components. Kevlar rope adds durability with its high strength and tear resistance, while aerogel serves an important role in insulation, reducing energy loss.

The design effectively creates a setting where algae cultivation thrives. It blends functional elements with advancements in material technology, all while emphasizing ecological responsibility and efficiency in production.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
