A portable expandable home is a foldable container house that expands from a compact shipping size to a full living space. This portable container house folds down to one-third of its expanded size for low-cost transport. Two or three workers can unfold it in minutes when you need it. For construction site camps, disaster relief, remote offices, or affordable housing, this expandable prefab house is a smart solution.
YG Machinery offers 20ft, 30ft, and 40ft foldable container homes. Each model is made of Q235 steel with insulated sandwich panels. Different room layouts and exterior options are available. Whether you need a single unit for a backyard office or 50 units for a worker camp, YG has a portable expandable home for you.

How This Expandable Container House Saves You Money
Let us do a simple calculation.
Assume you have a construction project. You need to house 20 workers. You need 5 portable expandable homes (4 people per unit).
With traditional construction (modular office):
- On-site assembly is required: foundation + walls + electrical + plumbing
- Installation time: about 15 days
- Need 4 workers
- Assume each worker earns $80 per day
- Labor cost: 4 workers × 80×15days=∗∗80×15days=∗∗4,800**
- Material transport: 2 trucks needed
With portable expandable homes:
- Units are factory prefabricated and unfold on site
- Installation time: 1 day (2-3 workers)
- Assume each worker earns $80 per day
- Labor cost: 3 workers × 80×1day=∗∗80×1day=∗∗240**
- Folded size is 65% smaller, so 1 truck can carry 5 units
Your savings:
- Labor cost saved: 4,800−4,800−240 = $4,560
- Time saved: 14 days
- Transport cost saved: 1 truck of shipping
Assume one 20ft portable expandable home costs 8,000.Fiveunitscost8,000.Fiveunitscost40,000.
Your payback period:
Based on labor savings alone, 40,000÷40,000÷4,560 = about 8.8 projects
After that, every project saves you money. Your actual savings depend on your local labor rates and project volume. Use your own numbers to calculate.
Folded Size Saves Transport Cost
A portable container house folds down to a very compact size. This is one of the biggest advantages of this product.
| Model | Expanded size | Folded size | Volume reduction |
| 20FT | 6320x5900x2480mm | 2200x5900x2480mm | 65% smaller |
| 40FT | 6240x11800x2480mm | 2200x11800x2480mm | 65% smaller |
| Small model | 4820x5900x2480mm | 700x5900x2480mm | 85% smaller |
What this means for your business:
Lower shipping cost – One standard 40ft shipping container can hold multiple folded units. You pay for one container instead of five.

Customer Cases
Case – USA: Construction Company in Texas
A construction company in Houston, Texas, needed temporary housing for 40 workers on a highway expansion project. The project would last 18 months. Building traditional worker housing was too expensive and too slow.
They bought 10 units of YG 20ft portable expandable homes. Each unit houses 4 workers with bunk beds, a small kitchen, and a bathroom.
The units arrived folded on two flatbed trucks. Four workers installed all 10 units in one day. The workers moved in the next morning.
Results:
- Installation time: 3 day (compared to 3 weeks for traditional housing)
- Labor cost for installation: 960(4workers×960(4workers×60 × 4 hours)
- Traditional housing would have cost $15,000 in labor and materials
- Savings on this project alone: over $14,000
The project manager said: “The foldable container houses saved us time and money. We set up camp in one day. The workers are comfortable. When the project ends, we will fold them up and move them to the next site.”
