Rainwater Harvesting Residence Built with Rice Straw and Local Stone

Project in-detail

Utilizing rice straw for insulation and stone for durability, this residence incorporates a rainwater harvesting system and flexible design to create an efficient living space in just 25m².
5 key facts about this project
01
Rainwater harvesting system integrated into the roof design for efficient water management.
02
Walls constructed with rice straw for improved insulation and sustainability.
03
Local stone used for the foundation to enhance stability and environmental adaptation.
04
Flexible interior layout allows for adaptable living spaces in a compact footprint.
05
Slatted wooden walls facilitate natural ventilation while maintaining privacy.
The architectural project under review is a compact 25m² dwelling designed with sustainability and bioclimatic principles at its core. It is a small-scale residential structure that integrates efficient design and eco-friendly materials to create a functional living space. The overall concept embraces minimalism while ensuring comfort and resourcefulness.

The house serves as a prototype for sustainable living, showcasing an efficient layout that maximizes the use of natural light and ventilation. It addresses the need for affordable housing solutions in urban settings by utilizing innovative design approaches that can be replicated in various contexts.

Sustainable Materiality and Structural Design

This project distinguishes itself through its careful selection of materials and structural integrity. The primary materials used include wood, stone, rice straw, and clay, each chosen for their environmental benefits and local availability. Wood serves as the main structural component, providing support while contributing to the overall warmth of the space. Stone is utilized in the foundation to enhance durability and moisture resistance. The incorporation of rice straw in the walls improves insulation, while clay helps with thermal regulation, creating a comfortable indoor climate.

A significant design feature is the uniquely shaped roof, which promotes rainwater harvesting. This approach highlights the architectural focus on resource management, allowing the structure to capture and store water efficiently. The integration of transparent tarps for climate control is another unique aspect, as it supports natural light flow and facilitates ventilation while maintaining temperature stability.

Innovative Climate Adaptation Strategies

This project utilizes specific climate adaptation strategies that set it apart from similar architectural designs. The open-plan layout of the interior fosters flexibility and adaptability, enabling occupants to modify the space according to their needs. Furthermore, the incorporation of slatted wooden walls allows for effective cross-ventilation, ensuring fresh air circulation while providing a level of privacy.

Additionally, the implementation of renewable energy systems, such as flexible solar panels on the roof, enhances the sustainability of the design. These features contribute to a lower carbon footprint, demonstrating a commitment to ecological responsibility within the architectural framework.

Overall, this architectural project exemplifies a forward-thinking design approach that effectively combines sustainability with functionality. The use of local materials, innovative strategies for resource management, and an adaptable living space highlights the potential for small-scale architecture to address pressing environmental concerns.
