Choosing a prefab modular building usually comes down to what the structure must hold, where it will sit, and how much of your budget goes to the shell itself. The four options here take different approaches: a compact mobile office, a wide fabric shelter for vehicles or equipment, an expandable tiny home, and a long steel self-storage building. Their listed prices run from $12,500 to $18,999, so the decision is less about price range and more about matching the building type to the job.
Quick Take
If you want a ready-to-use space, the Chery Industrial 13x7FT mobile office is the prebuilt option in this group. If you need wide-open square footage for vehicles or inventory, the Hills Industrial 50x80x26-foot dual-truss shelter is the largest covered footprint here. For a residential-style expandable layout, the Portable Prefabricated Tiny Home offers a 19x20-foot plan. And for compartmentalized storage, the DURO Steel Mini Self Storage building provides a 100-foot-long footprint.

Product Notes
Chery Industrial 13x7FT Mobile Prefab Office with Bathroom & Bedroom
This mobile office is the only prebuilt building in this group, meaning the structure comes as a complete unit rather than a bundle of parts. Its 13 by 7.2-foot footprint and 8-foot height suit a single workstation, a temporary bedroom, or a site office, and the integrated bathroom with shower and flush toilet makes it fully self-contained. The steel frame and 1-year warranty cover the basics of a portable building. The trade-off is space: 13 feet in length leaves little room for a full living layout, so this is best for one person or a compact live-work setup.
Hills Industrial Prefab Building Shelter Dual Truss PVC 50x80x26 ft
This 50x80-foot shelter with a 26-foot peak height offers a broad open area for equipment, vehicles, or inventory. The dual-truss frame is heavy-duty and the PVC cover makes it a practical choice for fleet parking, contractor yards, or agricultural cover. It comes new in crate and is still packaged, so you are buying an unassembled structure. That means you are responsible for transportation and assembly. The listed specification of 0 bathrooms reinforces that this is a working shelter, not a living space.
Portable Prefabricated Tiny Home 19Ft X 20Ft, Mobile Expandable Prefab House
This expandable tiny home is the only residential-oriented option in the group, with a 19x20-foot plan and an 8-foot ceiling height. It comes from the United States and includes Smart Living and Universal Design features, plus a 10-year warranty. The unit requires assembly, so you are not getting a prebuilt shell; the color is BROWN, which may limit exterior customization. It also carries the highest listed price in this set, reflecting a livable layout rather than a basic utility shell. If you want a portable dwelling that can be expanded on site, this is the direct match.
DURO Steel Mini Self Storage 20x100x8.5 Metal Building Prefab Structure
This steel structure is built for compartmentalized storage, with a 20x100-foot footprint and 8.5-foot walls plus 9x7-foot roll-up door openings. IBC-compliant engineering and a full set of erection drawings are included, which makes it a strong candidate for a planned self-storage facility. The roll-up doors themselves are not included, so those need to be sourced separately. With a snow load of 30 PSF and wind load of 115 MPH, it is rated for a defined set of site conditions. The 100-foot length is the longest in this comparison, and the 20-foot width gives a mix of long rows with individual compartments.
Final Recommendation by Use Case
If you need a ready-to-use live-work space, the Chery Industrial 13x7FT Mobile Prefab Office is the compact unit that includes a bathroom and bedroom. For large open covered storage, the Hills Industrial Dual Truss PVC shelter provides the largest listed covered footprint and can handle vehicles or equipment once you arrange assembly. For a portable home you can expand, the Portable Prefabricated Tiny Home brings a US-made layout with Smart Living features. For dedicated storage rows, the DURO Steel Mini Self Storage building gives you a long engineered steel structure with multiple door openings, and you supply the roll-up doors.
