Rainwater Harvesting Homes Constructed with Recycled Blocks and Galvanized Steel

Project in-detail

Constructed with recycled blocks and galvanized steel, these elevated homes are designed to withstand flooding while harnessing rainwater and solar energy, providing sustainable housing solutions for local communities.
5 key facts about this project
01
The housing units are elevated on stilts to prevent flooding and manage stormwater effectively.
02
Construction utilizes readily available local materials, empowering residents to engage in self-building processes.
03
The design features a modular grid system, allowing for easy configuration changes to meet individual family needs.
04
Solar panels are integrated into the roofs to promote energy efficiency and sustainability.
05
Communal spaces are incorporated for community gardening, fostering collaboration and social interaction among residents.
The project "Buy-Build-Adapt" provides a thoughtful architectural response to the pressing need for affordable housing within vulnerable communities. In an era where rapid urbanization and escalating housing costs create significant barriers for many, this initiative challenges conventional building practices by establishing a model that emphasizes accessibility, sustainability, and user empowerment.

At its core, the architecture of "Buy-Build-Adapt" represents a fundamental shift in the way housing can be approached. The design is not solely about creating physical structures; it is about fostering community resilience and enabling individuals to have a hand in the construction of their own homes. This self-built housing model empowers prospective residents, allowing them to become active participants in shaping their living environments.

The functional aspect of the project is defined by its modular design that accommodates various configurations and adaptations based on individual and communal needs. The framework employs a flexible grid system, which enables families to adjust the layout as their circumstances evolve over time. This adaptability makes each unit not just a static structure but a dynamic space capable of growing alongside its inhabitants.

A key architectural feature is the elevation of the homes on stilts, which provides protection against flooding while also facilitating efficient water management systems. This design choice underscores a commitment to environmental responsiveness, particularly in areas prone to climate-related challenges. The infallible incorporation of large windows enhances natural ventilation and daylighting, creating inviting indoor spaces while reducing reliance on artificial lighting and mechanical cooling systems.

Materiality plays an essential role in this project, with careful attention paid to sustainability and local availability. The use of materials such as recycled wood, galvanized steel, and eco-friendly concrete demonstrates a commitment to reducing the environmental impact of construction. Furthermore, the selection of materials that can be easily sourced from local hardware stores reinforces the project's focus on accessibility. Residents are encouraged to use their creativity and resourcefulness in sourcing the materials needed for construction, promoting a sense of ownership and pride in their new homes.

The design also thoughtfully integrates renewable energy solutions, notably through solar panels that not only power the homes but also align with contemporary sustainability practices. Coupled with systems for rainwater harvesting, these features showcase an architectural approach that prioritizes environmental stewardship while providing practical benefits for the occupants.

Unique to the "Buy-Build-Adapt" project is its emphasis on community interaction and social cohesion, with spaces designed for communal gardening and shared facilities that foster cooperation among residents. This social dimension highlights the important role of architecture in cultivating relationships and encouraging collective sustainability efforts.

In a world where housing crises are increasingly prevalent, the architectural ideas employed in the "Buy-Build-Adapt" project represent a practical and innovative strategy to overcome these challenges. By merging functionality with adaptability and sustainability, the project stands out as a viable solution for addressing the complex issues related to affordable housing.

For those interested in a deeper exploration of the architectural plans, sections, and designs that illustrate this project, a closer look at the presentation material will provide valuable insights into the practicalities and ideologies that underpin this forward-thinking initiative. The architecture of "Buy-Build-Adapt" invites an ongoing dialogue about the future of housing and community living, exemplifying a design approach that prioritizes human experiences alongside built environments.

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.
