Chery 13x7 Prefab Office vs DuroSPAN 20x40 Steel Building Kit: Which Fits Your Space?

A compact prebuilt office with bathroom and bedroom at $12,500 or a large 20x40 steel building kit at $9,995? See which prefab modular building fits your planned use.

Last updated Aug 17, 2026

Deciding between these two prefab modular buildings is really a choice between a finished, compact space and a large, open shell you plan to build out.

Quick verdict

If your situation calls for a compact, prebuilt live-work space, the Chery Industrial mobile office is the more complete package. If your situation calls for a large steel building kit to use as a garage, workshop, or storage building, the DuroSPAN option gives you far more square footage for a lower listed price.

Where each product wins

  • The Chery Industrial mobile office wins for convenience. It is an all-in-one layout with a bathroom and bedroom already included, so you are not starting from an empty shell. Its compact size makes it a better match for a small office, temporary living space, or remote workstation.
  • The DuroSPAN steel building kit wins for raw space. The listed footprint is much larger than the Chery unit's, and the title notes end walls are included. That makes it the stronger choice for a garage, shop, or large storage area.

Product notes

Chery Industrial 13x7FT Mobile Prefab Office with Bathroom & Bedroom

Chery Industrial 13x7FT Mobile Prefab Office with Bathroom&Bedroom

This is the one to pick when you need a prebuilt, compact building that already includes the rooms you would otherwise have to add. The listing describes a self-contained live-work unit with a bathroom featuring a shower, flush toilet, vanity basin, and an anti-slip floor, plus a bedroom in a 13 ft by 7.2 ft footprint with an 8 ft ceiling. The listed price is USD 12,500.00, and the structure is built from Q235 steel. The trade-off is space: at 13 ft long and 7.2 ft wide, it will feel tight if you plan to hold large meetings, store equipment, or use it as a workshop. The 8 ft height suits a small office or sleeping quarters more than tall shelving or vehicle storage.

If you are planning a garage, shop, or large storage building, the DuroSPAN kit provides a significantly larger interior for the listed price of USD 9,995.00. The title confirms that end walls are included, so that part of the building is part of the package. The listing also describes the G-SERIES ends as customizable, making the structure adaptable for office, retail, warehousing, workshop, or cottage use. The main limitation is that this is a building kit, not a prebuilt office: you are getting the steel structure and end walls rather than a small structure with rooms arranged for you. With a 40 ft length, 20 ft width, and 16 ft height, it also demands a much larger site than the Chery unit.

Final choice by use case

Choose the Chery Industrial mobile office if your prefab modular building needs to work as a small office, temporary living space, or remote workstation, all in a compact footprint. Choose the DuroSPAN steel building kit if your priority is a large open area for vehicles, tools, or equipment, and you are ready to work with a kit structure rather than a prebuilt interior. Both are legitimate options; the right one depends on whether you need a small finished space or a big empty shell.
