The Narrative

The Scoria House is a rejection of the fragile "glass box." Situated in the high desert's volatile climate, the design concept utilizes the site's natural 5-foot basalt outcropping not as an obstacle, but as a formal datum. We partially carved the private quarters into the scoria rock to anchor the home, while allowing the social volumes to cantilever over the ledge.

This move creates a "protected transparency"—deep-set, high-performance apertures that frame the horizon while shielding the interior from the harsh summer sun and mountain wind. The result is a refined sanctuary that honors the tension between the volatility of the landscape and the precision of human craft.

The Strategy

  • The Gear Library: Far more than a garage, this conditioned, museum-grade transition zone treats alpine equipment as art. It serves as the spiritual engine of the home, designed for the "4:00 AM start" ritual, featuring drainage for snowmelt and visibility from the main hallway.
  • WUI-Compliant Shell: To meet strict fire codes without sacrificing warmth, the exterior is clad in Shou Sugi Ban (charred timber) and fiber-cement panels, creating a fire-hardened "bark" that mimics the site's charred history.
  • The Basalt Float: The architecture navigates the topography by "floating" the public program over the existing lava flow, minimizing site disturbance while maximizing the psychological experience of the terrain
