Nearly four decades ago, in the mid-80s, I embarked on an ambitious journey with my former manager and a Swiss client of peasant background to design an earth-covered house in the Canton of Lucerne.
I recall that the spherical segment had a diameter of over 20 meters and a height of two stories, fully integrated into the landscape and covered with earth. Conceived 37 years ago, this project aimed to harness the inherent sustainability of the earth itself. However, it remained unrealized beyond the planning stage (building permit). Unfortunately, the project was not realized, but a double dome as a car dealership and auto garage workshop in Schaan, Liechtenstein was realized by our office at the same time.
Today, amidst a global resurgence of eco-friendly design, I reflect on this concept with renewed interest and recognize its potential to meet current environmental demands.
Historical Background
Earth-covered houses are not a novelty. They are a testament to our ancestral sophistication, with roots stretching back to prehistoric earth lodges and Neolithic settlements. These structures embody humanity's earliest attempts to live climate-resilient lives. Now, as we face urgent climatic challenges, these ancient strategies are re-emerging, redefined by modern needs for energy efficiency and sustainability.
Had the Lucerne project come to fruition, it would have become a prime example of architectural harmony with nature. This visualization represents the dreamed synthesis, a home enveloped by the earth, promising both minimal environmental impact and a deep connection with the surrounding landscape.
Binishell Technique:
The Binishell technique https://binishells.com/, a child of the 1960s, now reintroduced, demonstrates the versatility of reinforcement and concrete applied on an inflatable neoprene balloon. This innovation offers a durable, cost-effective approach to construction that can revolutionize social housing by reducing both economic and ecological footprints.
Monolithic Domes
Monolithic Domes symbolize the adaptability of modern construction. Their process, a union of air form, foam insulation, and concrete, results in structures that withstand the extremes of nature while saving energy. The application of this method in various climates and terrains underscores its universal potential.
Modern Interpretation
The current apex of earth-covered architecture, as depicted here, combines state-of-the-art materials with time-tested principles. These structures are living examples of sustainability, blending into their environments while offering unprecedented efficiency and comfort.
Conclusion
The revival of systems for earth-covered houses is not just a nod to our past but a step towards a sustainable architectural future. Their integration into contemporary practice reflects our commitment not only to environmental protection but also to creating spaces that enhance living conditions and aesthetic values.
