W700 is the most container-efficient model in our expandable house lineup. The 20FT version packs 6 units into a single 40HQ container — maximizing every cubic meter of shipping space and minimizing your per-unit freight cost. For bulk orders of 50+ units, the freight savings alone are substantial. The 5,900mm folded length is precision-optimized for 40HQ container dimensions, while 75mm insulated wall panels provide above-standard thermal performance.
