In October 2024, a real estate investment company in California, USA launched a temporary workers’ dormitory project in the suburbs of Las Vegas. Due to the long approval period of local building permits, slow construction period and high labor cost of traditional houses, the company finally chose to purchase a batch of expandable modular house from China YG, which is used to quickly set up a habitable, dismantleable and relocatable camp housing system. After 40 days of on-site use, the customer gave good feedback and indicated that they would continue to purchase additional units.

Actual Demand for Expandable Modular House in the U.S. Market
In recent years, there has been a gradual rise in demand for expandable modular houses in multiple states in the U.S. when faced with scenarios such as emergency relocation, site camps, and remote construction.
On the one hand, because of the general increase in housing costs, the temporary building solutions can ease the pressure of living;
On the other hand, in California, Texas, and other climate change or mountainous remote areas, the traditional building construction cycle is long, less flexible, and difficult to meet the rapid delivery requirements.
The client’s project manager mentioned, “We have considered buying wood frame houses or converting container houses, but the cost is high, customization is complicated, and transportation takes up a lot of space. In contrast, this expandable container house is compressed for transportation, quick to unfold on site, and can be installed by 2 people in 1 hour, which is perfect for our camp scenario.”

3 Advantages of Expandable Modular House
- Rapid deployment, saving labor and construction cost
The folded structure allows for compact transportation. Upon arrival at the site, there’s no need for a professional construction team—only one forklift and two workers can complete the installation. Our team pre-installs all electrical wiring and plumbing before shipping each house, so it can be installed and used immediately. This approach greatly shortens the construction cycle. - Solid structure, adaptable to a variety of climatic environments
It adopts a reinforced steel structure + anticorrosion treatment, with good wind and seismic performance, suitable for the southern United States hurricane areas or western high-temperature and arid areas. We provide anchor points on the roof to facilitate the fixing of wind-resistant ropes, and reserve holes for ground bolts at the bottom to enhance the stability of the whole site. - Upgradable Configurations to Enhance Comfort and Functionality
You can retrofit the container house with air conditioning, solar power generation systems, as well as bathroom and kitchen facilities. It is ideal for long-term residence, remote offices, on-site management, and more. You can freely partition the indoor space to accommodate 1 to 6 people. Some customers also use it as a display room, meeting room, or mobile kiosk.
Client Testimonials and Application Scenarios
In this project in the U.S., the client mainly uses the units to accommodate construction workers. Each unit includes two bedrooms, an ensuite bathroom, and a common area. The team installed double beds, lockers, small tables and chairs, air-conditioning, and lighting equipment in every room, which has significantly improved the site conditions.
The project manager gave positive feedback: “We are very satisfied with the quality and efficiency of these expandable prefab houses.” The installation process went smoothly, and staff reported that they are more insulated and comfortable than in the previous cubicles and that maintenance is simple at a later stage.”
At the end of the project, some of the modules were also recycled and transferred to another state for further use, demonstrating their good relocatability and reuse value.
