Product Q&A

Q:How is the house shipped? Does it come fully assembled?

To save on freight costs, the house is shipped in its folded state. One unit fits perfectly into a standard 40HQ container. It is 90% pre-assembled; you only need to expand the two wings after it arrives.

Q:How long is the delivery time?

Production typically takes 20-25 days. Shipping time depends on your location (e.g., 25-35 days to the USA/Europe).

Q:Is it difficult to install? Do I need a crane?

Installation is very simple. It takes 4-5 people about 2 hours to expand. You will need a crane or a heavy-duty forklift to lift the unit from the shipping container and place it on your foundation.

Q:Do I need a concrete foundation?

Not necessarily. You can place it on concrete piers, a gravel bed, or even a level solid ground. However, we recommend concrete piers for long-term stability and better drainage.

Q:Does the electrical and plumbing meet my country's standards?

Yes! We customize the electrical (UL/CE/AS/NZS) and plumbing (UPC/Watermark) based on your destination. Please let us know your country before ordering.
