Rammed Earth Walls and Photovoltaic Solutions in Sustainable Community Housing

Project in-detail

With rammed earth walls that enhance thermal mass and integrated photovoltaic systems, the design provides a sustainable housing solution for a transient population in the heart of Veracruz’s coffee plantations.
5 key facts about this project
01
Rammed earth walls enhance thermal mass and energy efficiency.
02
Integrated photovoltaic systems support off-grid living.
03
Large windows optimize natural ventilation and daylighting.
04
Community spaces encourage social interaction among residents.
05
Rainwater harvesting tanks are incorporated for effective water management.
The project involves a sustainable housing initiative located on coffee plantations in Veracruz, Mexico, designed to provide affordable living solutions for a migrant population. Central to its development, the project emphasizes the integration of sustainable practices with local craftsmanship while addressing the region's demand for environmentally responsible housing. The architecture reflects a bioclimatic approach that engages with the natural environment, optimizing energy efficiency and minimizing carbon footprint.

Sustainable Material Use
The architectural design utilizes a range of materials that enhance both functionality and sustainability. These include rammed earth and timber, which are sourced locally, reinforcing the project's commitment to ecological sensitivity. The building employs prefabricated QuadCore A WP LEC wall panels and QuadCore KS1000RW LEC roof panels, which provide structural stability while ensuring high thermal performance. Photovoltaic cells are incorporated to harness solar energy, furthering the objective of self-sufficiency. The design also integrates acoustic tiles (Trodilekt x-line Tway 10) to improve internal comfort through sound insulation, while rainwater harvesting tanks are implemented to manage water resources effectively. The use of thermal mass walls plays a key role in moderating indoor temperatures, reducing reliance on mechanical heating and cooling systems.

Community-Centric Design
The spatial organization of the housing units prioritizes communal living while providing private spaces for individuals and families. Communal areas, such as living and dining spaces, are designed to foster interaction among residents, facilitating a sense of community. The project features a stepped entry that enhances accessibility and creates outdoor gathering areas, allowing residents to connect with their environment. This thoughtful distribution of spaces reflects a design philosophy that values social equity and the well-being of occupants.

Bioclimatic Architecture Approach
The project's design actively responds to local climatic conditions, employing strategies that promote passive ventilation and natural light. Large windows are strategically placed to enhance cross-ventilation and daylighting, reducing energy consumption. The sloped roof is designed for efficient rainwater runoff while providing opportunities for the installation of photovoltaic systems. This bioclimatic architecture not only minimizes environmental impact but also addresses the need for comfortable living conditions in the humid tropical climate of Veracruz.

For a more in-depth understanding of the architectural plans, architectural sections, and overall design strategies employed in this project, readers are encouraged to explore the detailed project presentation. Engaging with these elements will provide valuable insights into the innovative architectural ideas that underpin this sustainable housing initiative.

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.
