Spherical Form Constructed with Compressed Earth and Recycled Steel for Sustainable Living

Project in-detail

Constructed using a combination of compressed earth blocks and recycled steel, the building’s spherical form maximizes natural light and ventilation while providing a sustainable living space.
5 key facts about this project
01
Constructed with a modular system for easy assembly and disassembly.
02
Integrates rainwater harvesting systems within the structure for resource efficiency.
03
Utilizes compressed earth blocks for thermal mass and sustainability.
04
Includes bio-digester systems to convert organic waste into biogas.
05
Designed with a spherical geometry to enhance natural light and airflow.
The architectural project "Terrae – The Worth of Our Soil" represents a conscientious approach to sustainable design. Situated in a context that emphasizes ecological harmony, the project integrates advanced building techniques with the natural landscape, promoting a symbiotic relationship between the built environment and the surrounding ecosystem. The primary function of the design is to provide adaptive living spaces while minimizing environmental impact.

The structure utilizes a spherical geometric framework composed of polygonal elements, resembling the form of a dodecahedron. This geometry not only enhances aesthetic appeal but also maximizes structural efficiency. The use of recycled steel for the skeleton minimizes the carbon footprint, while the application of compressed earth blocks as the main envelope reinforces thermal insulation, leveraging the earth's natural mass.

The use of wood for interior finishes provides a warm atmosphere, contrasting with the robust nature of the metallic and earthen materials. Translucent polycarbonate panels allow natural light to permeate the interior, thus reducing reliance on artificial lighting. Additionally, the incorporation of bio-digester systems illustrates a commitment to waste reduction, using organic matter to produce biogas, which furthers the project's sustainability goals.

Unique design approaches distinguish this project from traditional architecture. The construction system is modular, allowing for flexibility and adaptability to various climates and site conditions. This modularity ensures ease of assembly and disassembly, beneficial for potential relocations or extensions. Moreover, the innovative integration of rainwater harvesting systems demonstrates a practical approach to resource management, enhancing the building's sustainability credentials.

The project's emphasis on educational aspects is also noteworthy. It serves as a model for sustainable living, providing a space for learning and interaction about environmental stewardship. By incorporating technical cores that house plumbing and electrical systems within the structure, the design prioritizes ease of maintenance while maintaining aesthetic integrity.

For further insights into this project, including architectural plans and sections, potential visitors are encouraged to explore detailed presentations that elucidate the various architectural designs and ideas that contribute to the overall concept of "Terrae." This analysis highlights the project's potential as a template for future developments focused on sustainability and ecological integration in architecture.

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.
