robotically 3D printed earth bricks wrap multispecies habitat around olive tree

the pavilion combines computational fabrication with dryland agricultural knowledge to create a porous structure that regulates shade, heat, airflow, and moisture while providing niches for plants, insects, birds, fungi, and other species.

178 3D printed earth bricks form porous habitat around olive tree

BUSTAN, meaning ‘orchard,’ is a full-scale earthen pavilion developed by the Material Topology Research Lab (MTRL) at the Technion – Israel Institute of Technology and Weizmann Tree Lab for The Circle exhibition at Design Museum Holon. Built from 178 robotically 3D printed earth bricks, the structure is organized around a living olive tree, treated as the pavilion’s primary client. The bricks are made mainly from locally sourced soil mixed with bio-based plant fibers and mineral binders. Each brick is digitally designed and robotically printed with a specific geometry and surface texture, giving it an ecological function related to shade, thermal mass, airflow, moisture, or habitat.

The pavilion forms a porous wall that creates a microclimate around the tree’s canopy and root zone. Certain bricks shade the roots and reduce solar exposure, while thick earthen walls absorb heat during the day and release it at night. Openings near the top promote passive stack ventilation, and the layered soil profile in the planting zone retains moisture through capillary action.

Bespoke brick geometries also create niches for plants, insects, birds, small mammals, fungi, and biocrusts. As the earthen structure weathers and becomes inhabited, the project proposes architecture as part of an evolving living system rather than a fixed object.

Ancient agricultural practices meet robotic earth fabrication

BUSTAN draws on agricultural practices from the drylands of the Eastern Mediterranean and Middle East, where shade, soil, water, shelter, and local materials were used to create microclimates for cultivation. The project translates this environmental logic through computational design and robotic fabrication.

The earth is developed into an extrudable paste and deposited layer by layer by a robotic arm through a custom nozzle. Each brick type follows its own toolpath, producing differentiated forms and surfaces according to its ecological role. The process included local soil collection, material testing, binder development, robotic programming, and fabrication at the Technion Advanced Construction Center (TACC).

As part of MTRL’s research into material ecology, robotic fabrication, and landscape, BUSTAN brings these ideas together as a full-scale prototype that tests how computational tools and local materials can support tree cultivation and multispecies habitat.
