Stealth House

Stealth House: drape is an experimental 3D printed house exploring a new relationship between softness, primitive space, and digital construction technology.
The project utilizes layered mortar printing to create a flowing architectural skin resembling draped fabric. These undulating surfaces simultaneously contain structural elements, equipment, and openings, integrating function and form into a continuous spatial envelope. The rough layered texture and organic geometry embrace the unique uncertainties of large-scale additive manufacturing while generating a soft and human-centered architectural expression.
The cave-like interior dissolves conventional rectilinear housing composition and creates a primitive spatial experience shaped by light, shadow, and curved surfaces. Skylight illumination spreads across the layered mortar walls, producing changing atmospheres throughout the day.
The project also proposes a new architectural production system by integrating parametric design, high-precision rendering, robotic construction, autonomous layout technology, and 3D scanning. Stealth House demonstrates how advanced construction technologies can create emotionally resonant and socially adaptive architecture beyond conventional industrialized housing.
Stealth House also represents Japan’s first two-story concrete 3D printed housing project, demonstrating the practical and architectural potential of large-scale additive manufacturing in residential construction.
