Engineering Excellence for Rapid Overseas Deployment
The Flip Classic B is PackPrefab’s flagship 2-bedroom expandable living platform, built for international housing developers, contractors, resort operators, and municipal housing programs.
Engineered inside our 500,000 sq ft manufacturing hub, the Flip Classic B combines heavy-duty structural steel framing with high-pressure polyurethane (PU) thermal insulation. Each unit folds down to container dimensions for low-cost ocean freight and unfolds on site within hours into a complete 2-bedroom home featuring a pre-installed wet-room bathroom, pre-wired utility channels, and premium bamboo-fiber interior finishes.
Core Procurement Advantages
- Pre-Installed Bath & Plumbing: Factory-integrated toilet, shower, vanity, and drainage channels eliminate on-site wet trades.
- High Ocean Freight Density: Fit up to 2 fully equipped expandable homes in one 40ft High-Cube container to slash logistics costs.
- Extreme Climate Performance: Rated for 156 mph wind resistance, seismic Category E/F, and fire resistance up to 1 hour.
- Rapid Commissioning: Standard 2-worker installation completed in approximately 8 working hours with basic rigging tools.

Engineered to International Structural Codes
Global procurement projects require guaranteed structural reliability. The Flip Classic B platform is tested and calculated against rigorous wind, snow, seismic, and fire safety ratings so local permit approvals run smoothly.
- Wind Load Rating: Engineered to withstand wind speeds up to 156 mph (Category 4 Hurricane strength).
- Roof Snow Load: Tested for roof snow loading up to 31.3 psf (1.5 kN/m²).
- Floor Load Capacity: Heavy-duty floor framing rated for live loads of 41.8 psf (2.0 kN/m²).
- Seismic Resistance: Category E/F compliant for active seismic environments.
- Fire & Acoustic Rating: 1-hour structural fire endurance; sound insulation coefficient of 45 dB+.

Buyer Guidance & Logistics FAQ
Because the Flip Classic B folds down into an ultra-compact transport geometry, exactly two (2) fully outfitted units fit into a single 40ft High-Cube (40’ HC) ocean shipping container. This cuts overseas freight costs by up to 50% compared to non-folding modular units.
You will need a standard mobile crane or a 5-ton forklift to lift the unit off the flatbed trailer onto your prepared foundation pads. Once placed, a crew of 2 workers using standard hand tools and the included winching jacks can pull out the side wings and secure the roof and floor locking pins in about 8 hours.
Yes. Wiring runs, light fixtures, distribution boxes, and plumbing conduits are integrated into the walls during factory assembly. The bathroom wet-room arrives fully fitted with toilet, shower enclosure, and sink. You simply connect your external power main, water inlet, and waste drainage line at the designated exterior utility access panel.
Absolutely. For wholesale purchases and project orders (5+ units), we support custom exterior carved metal cladding colors, modified window/door placements, regional electrical standards (110V US / 230V EU/AU), and off-grid solar roof prep kits.
