Alpine Pair 480

Alpine Pair 480

Twin module — stacked or side-by-side

Two repeatable room modules designed to lock together on site for duplex, ADU pair, or small multi-unit pod. Shared marriage wall minimizes exterior surface; stair / corridor cores can be site-built or shipped as add-on.

  • Paired units reduce perimeter heat loss
  • Stacking pattern for 2–3 stories
