Algal Systems and Bioplastics Transforming Urban Living Through Sustainable Materials

Project in-detail

Utilizing algal systems and bioplastics, this Berlin residential initiative integrates sustainable materials and community-focused design to create a model for affordable urban living.
5 key facts about this project
01
Utilizes algal systems for water filtration directly integrated into the residential design.
02
Incorporates bioplastics derived from algae as key construction materials.
03
Features elevated living spaces that blend seamlessly with submerged algae cultivation zones.
04
Design includes modular units that allow for flexible community interactions.
05
Community gardens are strategically placed to enhance resident engagement and food production.
The ALGA architectural design project proposes a comprehensive approach to sustainable urban living in Berlin. This project emphasizes the integration of ecological considerations with residential development, addressing the dual challenges of affordable housing and environmental restoration. Central to its concept is the innovative use of algae to purify water and enhance the local ecosystem while providing economic opportunities for residents.

Unique Features in Design and Function

The ALGA project distinguishes itself from conventional housing developments through its incorporation of active community engagement in environmental management. It is designed to foster a sense of ownership among residents, encouraging them to participate in the cultivation of algae for water filtration and prosperity. The project layout includes elevated platforms mixed with submerged areas for algae growth, creating a diverse set of living environments.

The use of sustainable materials such as wood, concrete, and algal bioplastics supports the project's ecological goals. The integration of community gardens and pollution harvesting stations within the residential framework enhances the relationship between inhabitants and their environment. This promotes sustainable practices while allowing residents to cultivate food and participate in eco-friendly living.

Architectural Integration and Spatial Organization

The design emphasizes open spaces that promote social interaction while balancing the built and natural environments. Spaces are arranged to foster communal activities, blurring the boundaries between private and public areas. Observation points are strategically placed to maintain a connection to nature and encourage leisurely pursuits.

Functional zones are clearly delineated, allowing for community gardens to thrive alongside living quarters. Pollution harvesting stations serve a dual purpose—cleaning contaminated water and generating potential revenue from the harvested algae. This strategic layout not only enhances the aesthetic qualities of the project but also maximizes the practical benefits of its ecological initiatives.

The ALGA project serves as a case study in applying innovative architectural solutions to urban challenges. To gain deeper insights into the project’s architectural plans, sections, designs, and ideas, readers are encouraged to explore the detailed project presentation further. There is much to learn from the intricate relationship between design and function established within this thoughtful architectural endeavor.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
