Vertical Structure of Concrete and Bamboo Enhancing Urban Wetlands with Natural Filtration

Project in-detail

A vertical framework of concrete and bamboo integrates natural filtration systems to transform urban wetlands into functional community spaces dedicated to wastewater management and ecological education.
5 key facts about this project
01
Vertical design maximizes space in dense urban settings while enhancing ecological functions.
02
Utilizes bamboo structurally to promote sustainable material use and reduce carbon footprint.
03
Incorporates native vegetation in filtration beds for efficient water purification and biodiversity support.
04
Features cascading filtration systems that mimic natural wetland processes for effective wastewater management.
05
Includes community spaces that serve educational purposes, fostering local engagement with environmental issues.
The Vertical Wetlands project in Nakivubo, Kampala, represents a thoughtful exploration of urban ecological architecture. This initiative merges the essential functions of wastewater treatment with community engagement through innovative design. By elevating the use of wetlands within the urban fabric, the project addresses environmental concerns while providing functional public space.

The structure consists of twin towers that employ a vertical design to optimize land use in a densely populated area. The key function of the project is to treat wastewater naturally through a series of filtration beds integrated vertically into the architectural framework. This approach not only maximizes space but also enhances the aesthetic appeal of the site, transforming a utilitarian function into a community asset.

The architectural design incorporates various elements that reflect a deep commitment to sustainability, making this project distinct. The use of concrete as the primary structural material ensures durability, while bamboo serves as a lightweight alternative in parts of the design, promoting sustainable sourcing. Additionally, the integration of vegetative filtration media underscores the project’s ecological emphasis by utilizing native plants specifically chosen for their ability to purify water naturally. This unique combination of materials and techniques illustrates a comprehensive understanding of natural processes and their application within an urban context.

In contrast to traditional wetland designs, the Vertical Wetlands employs a multi-level cascading system of filtration beds that facilitate both water treatment and biodiversity. This innovative vertical workflow allows for diverse ecological interactions and opportunities for public engagement. The project also includes communal spaces, such as educational facilities and observation decks, encouraging local residents to interact with their environment and learn about the importance of ecological systems.

To gain deeper insights into the architectural execution of the Vertical Wetlands, including architectural plans, architectural sections, and architectural designs, interested readers are encouraged to explore the project presentation. This exploration will provide a comprehensive understanding of the architectural ideas that underpin this significant urban intervention.

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.
