Product Overview

The Trailer-mounted Double-wing Extension House is a highly mobile expandable container house integrated onto a rugged trailer chassis. Designed for rapid deployment and maximum flexibility, this towable modular building combines the durability of a steel structure with the convenience of a mobile home that can be relocated effortlessly.

Transported as a compact flat-pack unit, it unfolds mechanically or manually on-site to double or triple its usable area, creating a spacious living or working environment in minutes. With complete electrical and plumbing systems pre-installed, this portable cabin is truly plug-and-play — ready for immediate occupancy upon arrival.

This versatile prefab house is ideal for temporary and semi-permanent housing across construction, mining, oil & gas, emergency relief, military operations, and remote site management.
