Why modular
Factory-built quality. Field-built feels.
Traditional construction takes 12–18 months and exposes materials to weather, theft, and on-site labor variability. Modular factory-builds happen in a controlled environment — precision, speed, and quality you can't get on a job site.
120-day timeline
Permit-to-keys in 4 months. Factory precision cuts traditional build time in half.
Connectable system
Connectable, stackable, expandable BioBox modules. Single-unit homes, multi-unit configurations, multifamily — all from the same system.
Ships worldwide
Wall panels, coatings, steel, and all materials shipped directly to your site, ready for assembly. Worldwide delivery available.
50% lower energy
Continuous Rockwool + Polyiso insulation eliminates thermal bridging. Hot-roof design prevents attic condensation.
Hurricane-rated 200+ MPH
Steel-frame system with FEMA-certified fiberglass sheathing. Same disaster-grade spec as our luxury builds.
Toxin-free interiors
VOC-free finishes, MgO board (zero formaldehyde), inorganic materials throughout. Passes California IAQ.
Three principles
Connectable. Stackable. Expandable.
One modular system. Infinite layouts. Start with a single 400 sq ft unit; expand to 2,400+ sq ft as your needs grow. Connect units side-by-side or stack vertically for multi-story builds.
Connect
Modules link side-by-side via integrated connection points. Add a kitchen, an office, a guest suite — without touching the main structure.
Stack
Steel-frame structure supports multi-story stacking. Two-story homes, multifamily duplexes, or commercial mid-rise — same system.
Expand
Start small. Add modules later. Your home grows with your family — no demolition, no chaos, no re-permitting from scratch.
Configurations
Sized to your life.

Frequently asked
Modular questions.
What's the difference between modular and mobile homes? +
Both are factory-built. Modular homes are built to local building code (IBC/IRC) and placed on permanent foundations — they're treated like site-built homes for financing, taxes, and resale. Mobile/manufactured homes are built to federal HUD code and can be placed in mobile-home parks. BioBox offers both.
How does the 120-day timeline work? +
Day 0: contract signed. Days 1–30: design + engineering + permit submission. Days 30–90: factory build (parallel with site prep). Days 90–110: delivery + on-site assembly. Days 110–120: utilities, finishes, certificate of occupancy. Faster than any traditional construction timeline.
Can I expand my BioBox home later? +
Yes — that's the point of the modular system. Connect additional modules side-by-side or stack vertically without demolishing existing structure. New modules ship from the factory and assemble in days.
How is energy efficiency 50% better? +
Continuous exterior insulation (Rockwool + Polyiso) eliminates thermal bridging — the biggest source of heat loss in conventional construction. Hot-roof design eliminates attic condensation. Combined with high-R walls and tight factory-controlled assembly, energy use drops ~50% vs. code-minimum homes.
Where do you ship? +
Modular units ship anywhere in the continental US, plus international with appropriate logistics. Florida and Southeast US ship times are 60–90 days; further-out destinations may add 1–4 weeks for sea freight or trucking.
