Foundation Engineering for Every Boxabl

Backyard and infill dwellings in Casita and Familia styles — the highest-volume category in the catalog.

  600 sf · 2 bed / 1 bath
• Familia 800$111/sf · ~$88,800
  800 sf · 3 bed / 1.5 bath

Foundation angle: Simple perimeter foundations; ADU zoning is usually the gating item, not the structure.

Full-size primary homes — attached or detached — assembled from multiple boxes.

• Single Family 2000 — ATT$108/sf · ~$216,000
  2,000 sf · 3 bed / 2.5 bath
• Single Family 2000 — DET$108/sf · ~$216,000
  2,000 sf · 3 bed / 2.5 bath
• Single Family 2400$103/sf · ~$247,200
  2,400 sf · 4 bed / 3.5 bath

Foundation angle: Large continuous footprints where module-connection layout and settlement control drive the design.

Single-story spread plans — more boxes side by side, no stacking.

• Ranch 1200$104/sf · ~$124,800
  1,200 sf · 2 bed / 2.5 bath
• Ranch 1400$105/sf · ~$147,000
  1,400 sf · 3 bed / 2.5 bath

Foundation angle: Long-run footings; slab or crawlspace selected by frost depth and soil.

Attached multi-story units built from stacked boxes.

• Townhome 1200$113/sf · ~$135,600
  1,200 sf · 3 bed / 1.5 bath
• Townhome 1600 — v2$120/sf · ~$162,600
  1,355 sf · 3 bed / 1.5 bath
• Townhome 1600 — v3$124/sf · ~$168,020
  1,355 sf · 3 bed / 2.5 bath

Foundation angle: Stacked gravity loads and shared load paths — closer to conventional multifamily engineering than to a Casita slab.

Stackable apartment units for multifamily buildings up to three stories.

• Garden Apartment — Studio$124/sf · ~$49,600
  400 sf · Studio / 1 bath
• Garden Apartment — 1 BD$115/sf · ~$69,000
  600 sf · 1 bed / 1 bath
• Garden Apartment — 2 BD$100/sf · ~$80,000
  800 sf · 2 bed / 1 bath

Foundation angle: Cumulative multi-story loads require true multifamily-grade foundation systems.

HUD-code manufactured homes at set unit prices — the most financing-friendly entry point.

• HUD — Studio$66,900 set price
  240 sf · Studio / 1 bath
• HUD — 1 BD$76,200 set price
  370 sf · 1 bed / 1 bath
• HUD — 2 BD$77,200 set price
  480 sf · 2 bed / 1 bath

Foundation angle: HUD homes use the manufactured-home foundation pathway — including the HUD-compliant PE certification letters we already provide.

High-density crew housing — the most beds per square foot in the catalog.

• Workforce 600$132/sf · ~$79,200
  600 sf · 3 bed / 1 bath
• Workforce 800$116/sf · ~$92,800
  800 sf · 4 bed / 1.5 bath

Foundation angle: Repeatable per-pad foundation packages across many units — where volume engineering pays off.

Park model and towable RV-code units, including the Baby Box.

• Park Model RV — Studio Casita$124/sf · ~$49,600
  400 sf · Studio / 1 bath
• RV Travel Trailer — Baby BoxOn request
  Towable · NFPA 1192

Foundation angle: No foundation by default — pad, leveling, and engineered tie-downs; convertible to real property.

Large luxury configurations — headlined by the 7,400 sf "White House."

• White HouseOn request
  7,400 sf · custom

Foundation angle: Complex footprints often mix foundation systems — engineered as one integrated structure.

Boxabl's round concept unit — the most unconventional style in the catalog.

Foundation angle: A circular footprint means a fully custom foundation — exactly the kind of one-off we quote directly.
