First Earth Rammed House in Poland to Begin Construction in 2027

The first residential building in Poland constructed using earth ramming technology is set to begin construction in spring 2027. The project, developed by eKodama Studio, will feature a total area of 70 square meters and a usable area of 85.08 square meters. The house will consist of four rooms, a living room, and two bathrooms across two floors, with the ground floor designated for family space and the upper floor for bedrooms. This innovative design aims to combine modern energy-efficient architecture with traditional earth ramming techniques, which were historically used in regions such as Greater Poland, Kuyavia, and Silesia.

The idea to utilize this traditional method originated from the investors themselves, who sought a healthy living environment. According to architect Magdalena Górska, the investors were determined to use this technology after extensive research and participation in workshops abroad. The construction cost is expected to be 20-40% higher than that of a similar house built using frame technology due to the weight of the walls and the labor-intensive process of ramming the earth.

The house will utilize natural materials to create a stable microclimate. The walls made of rammed earth consist of a natural, unburned mineral mixture of gravel, sand, and clay, which does not emit harmful volatile compounds. The high thermal mass of the walls protects the house from overheating in summer and gradually releases stored heat in winter. Additionally, the hygroscopic properties of clay help regulate humidity, reducing conditions favorable for mold growth. Typically, the humidity in a rammed earth house ranges from 40 to 60%, which is optimal for human health.

Moreover, the walls constructed in this manner can also dampen high-frequency electromagnetic waves, contributing positively to health. The rammed earth will not only serve as a structural material but will also be part of the interior architecture, eliminating the need for plaster and paint due to the natural horizontal layering of the earth. Górska emphasized that for the investors, this represents the healthiest living environment possible.

The earth used for construction can potentially come from the site itself, provided it is clayey and meets the necessary parameters. Testing the soil in a laboratory is essential to ensure its suitability for ramming.

This project represents a significant step forward in sustainable building practices in Poland, showcasing the potential of traditional methods in modern architecture.
