Architecture meets robotics to shape a sustainable future.

prinTerra is an innovative architectural initiative that fuses advanced 3D printing technology with environmental sustainability to create a self-sufficient, low-carbon desert village. Developed by a multidisciplinary team at Iran University of Science and Technology, this project envisions a future where construction is both automated and ecologically integrated.

At the heart of prinTerra lies a mobile Cartesian 3D printer, engineered to operate on challenging terrains using local soil as its primary construction material. This robot autonomously prints modular housing units—layer by layer—dramatically reducing human labor, material waste, and carbon emissions. The process is optimized to run during cooler hours of the day to prevent premature material drying.

Beyond robotics, the project is deeply rooted in passive design strategies. The architectural forms draw inspiration from cacti, adapting to harsh climatic conditions with minimal energy consumption. Domes, shading elements, and semi-open spaces are strategically designed based on climatic simulations to ensure thermal comfort throughout the year.

Complementing the built environment is a landscape plan featuring native plant species that serve as natural windbreaks and cooling systems. The integration of solar panels, vertical farming, and smart home technologies further enhances the sustainability and livability of the complex.

prinTerra is more than a construction project—it is a visionary experiment in autonomous, climate-responsive, and community-oriented architecture. By merging computational design, robotic fabrication, and ecological thinking, it sets a precedent for future developments in arid and remote regions across the globe.

Landscape Design

The landscape design of prinTerra integrates ecological resilience with spatial functionality. It enhances outdoor comfort through native vegetation, topographical manipulation, and environmentally responsive zoning.

Contextual Response

Located in the central desert of Iran, the site is exposed to intense solar radiation and seasonal winds. Natural hills to the north and west serve as protective barriers, while artificial elements shield the remaining edges.

Native Plant Strategy

Uses two indigenous species:

  • Tamarix Aphylla (10-15m windbreaker trees)
  • Seidlitzia Rosmarinus (2m shrubs)

Planted along southern/eastern edges as natural shields requiring minimal water.

Windbreak & Shading

Plant rows and built walls reduce wind intensity and create shaded pockets. Modular units arranged to cast mutual shadows during hottest hours.

Microclimate Engineering

Strategic excavation reduces ground radiation from 2500 to 1500 kWh/m². Sunken areas provide cooler gathering zones and improve thermal comfort.

Semi-Domes

Expand shaded areas and create transitional zones between indoors/outdoors. Reduce direct radiation on main domes while providing comfortable gathering spaces.
