An expandable container house is a factory-built modular dwelling that folds flat for international shipping and expands on-site to full living width — typically doubling or tripling the usable floor area in under two hours, without cranes or specialist construction crews.
Unlike basic shipping container conversions, a quality expandable container home arrives from the factory 80–90% complete — with structural frame, insulated wall panels, double-glazed windows, pre-wired electrical system, and pre-plumbed bathroom already integrated. On-site work is limited to foundation preparation and final utility connections by licensed local tradespeople.

Leading Expandable Container House Manufacturer: Factory-Direct Foldable Prefab Homes
As an innovative brand dedicated to the field of prefabricated architecture, UVO specializes in the R&D and manufacturing of prefabricated container homes. UVO ensures a reliable supply chain with 400+ units monthly capacity, delivery time is 20-30 days, exported to 50+ countries and tailored OEM/ODM solutions for global projects. Our expandable prefabricated homes are widely used in granny flats, AUDs, residences, vacation homes, offices, and commercial spaces.We comply with regulatory requirements across multiple regions and countries, having obtained the following certifications; we meet AU/NZ (SAA/WaterMark) 、US/Canada (UL/CE) and NATA asbestos-free certification standards. (We also offer NCC building permits and OC residence permits for the Australian market.)
Professional-grade expandable prefabricated house structural system
Reinforced Galvanized Structural System
We use full-size 210×150×160mm galvanized corner fittings and high-grade Q235 structural steel for all main beams and columns, with a yield strength exceeding 235MPa. This heavy-duty framework ensures no deformation even after repeated lifting and long-term use, while the hot-dip galvanized finish provides excellent corrosion resistance, preventing rust and extending the service life.
Professional Surface Treatment
Unlike ordinary paint, we adopt powder coating + baking process for all structural parts, with strict temperature and time control during production. The eco-friendly powder coating is recyclable, offers a 3+ year lifespan without fading, and creates a uniform, scratch-resistant surface that outperforms traditional paint in durability and environmental performance.
A1-grade fire-resistant and thermally insulated wall panels
All models come standard with a 50/75/100/120mm high-density rock wool insulation layer, meeting the A1 fire-resistant standard. With a thermal conductivity as low as 0.038W/(m·K), they utilize a composite wall system of "rock wool + moisture-proof membrane + metal panel," and can be upgraded to polyurethane, with a thermal conductivity as low as 0.024W/(m·K).
Superior Waterproof & Sealing System
Every expandable container undergoes 100% water tightness testing before delivery. The wall panels and roof are designed with adouble waterproofing system using structuralsealant and butyl tape, and have passed a 100%waterproofing test to ensure long-term leak-freeoperation.
Corrosion-Resistant & Low-Maintenance Design
From galvanized steel frames to powder-coated surfaces, every detail is designed for low maintenance. The rust-resistant materials eliminate the need for frequent repainting or repairs, making our expandable container houses ideal for remote areas, construction sites, or long-term residential use.

Prefabricated folding house factory Installation Guide
The product is 90% prefabricated before leaving the factory, with all water and electricity systems, interior trim, and accessories already tested and installed. On-site installation requires only 2-3 people using simple specialized equipment:
The first step is to unlock the fixing devices; the second step is to activate the extension mechanism. The house can be fully deployed within 10 minutes. Subsequent steps involve simple pipe connections and corner securing, allowing for full delivery and use within 1-2 days. No complex foundation is required; the trailer version can be directly installed and used, while the standard version adapts to various terrains, truly achieving "rapid deployment and immediate use."
Expandable Modular House Transportation
Designed based on standard container dimensions, UVO expandable container houses enable convenient global transportation. When folded up, the product fully complies with international sea and land transportation standards. A 40HQ container can carry two 20ft container houses or one 40-foot container house.
