Constructed from recycled plastic and hybrid roof panels, this compact shelter provides sustainable living solutions in the densely populated environment of Kibera.
5 key facts about this project
01
Constructed primarily from recycled plastic, reducing waste in the environment.
02
Integrates a hybrid roof design that combines multiple materials for enhanced durability.
03
Features a veranda made from repurposed car wheels, promoting sustainable practices.
04
Designed for efficient space utilization within a compact 25-square-meter footprint.
05
Incorporates autonomous waste management systems to improve local sanitation and health.

The design for Kibera focuses on addressing the severe housing needs of its population, which is estimated to be around 1 million people. Located in Nairobi, Kenya, Kibera is known for its high density and informal settlements. The aim is to create living spaces that are both functional and sustainable. The overall concept emphasizes small shelters that maintain a connection to the community while making use of local materials and versatile design strategies.

Design Concept

Kibera Mount Shelter is a key example of this approach, featuring a compact footprint of 25 square meters. Its design draws inspiration from the surrounding mountainous landscape, particularly referencing Mount Kenya. This connection helps ground the structure in its context. The interior layout includes essential spaces such as a living room, bedroom, kitchen, and bathroom, all organized to use space efficiently while supporting everyday activities.

Material Selection

Material choices play a fundamental role in the project. Plastic brick panels form the walls, providing a lightweight structure and good thermal insulation, which is important given the climate. The roof consists of hybrid panels made from a mix of plastic and sand, ensuring durability while minimizing environmental impact. Solar panels are incorporated into the design, providing renewable energy and enhancing the dwelling’s self-reliance.

Emphasis on Recycling

Recycling is a central theme in the design. The project incorporates recycled plastic, which reflects the local reality of plastic waste. Using these materials offers both aesthetic and functional benefits. It highlights a commitment to sustainability while addressing local material availability. The design demonstrates how waste can be transformed into a resource for building.

Autonomous Systems

The integration of autonomous waste management systems is another significant feature that addresses health and sanitation issues encountered in Kibera. The design includes systems for water collection and treatment, thereby enhancing living conditions. This focus on self-sufficiency illustrates a sustainable approach tailored to the needs of the community.

A noteworthy detail is the veranda, accessed by steps made from recycled car wheels. This feature creates an outdoor living space and symbolizes the creative possibilities of using available resources. It adds a layer of practicality while reinforcing the project’s sustainable objectives.

`
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.
