Regolith House leverages 3D printing technology and innovative materials to construct spaces that support individuals and families while fostering community. Our design explores the formal potential of 3D-printed architecture by redefining the fundamental unit of architecture: the line. Through the concept of Living Lines, we propose new wall types conceived as linetypes to expand on 3D printing standards. These walls introduce variation for added uses and privacy, eliminating interior doors and partitions for greater efficiency.

Our proposed wall types include: (A) a super-thin textured wall for dimension and vine growth, (B) a thin corrugated interior wall using shape for structure, and (C) a deep wave cavity wall for nooks and programmatic features. Each print can include up to four living units, approximately 450 square feet each, designed to combine uniquely and adapt to various neighborhood contexts—ranging from accessory dwelling units (ADUs) to small-scale developments.

To achieve affordability, our design incorporates simple building systems and prefabricated assemblies that integrate with the 3D-printed lines. The basic unit plan centers around a prefabricated kitchen insert with shared plumbing walls. Rotating the insert transforms two units into a three-bedroom home. Curtains and 3D-printed geometries replace doors and partitions, creating open, light-filled interiors with floor-to-ceiling windows and skylights. Exterior paths wind through landscaped courtyards, enhancing connectivity and privacy. The roof, composed of modular components, doubles for four housing units, while prefabricated foundation formworks nest for efficient transport. These design efficiencies minimize waste and costs, aligning with the goal of a $99,000 house.

At its core, Regolith House demonstrates that affordable housing can embody the ambition, beauty, and sustainability of our most iconic buildings, enhancing quality of life and fostering community through thoughtful design.
