Mobile Expandable Prefab House 16½ft × 20ft
Discover flexible space with our
Mobile Expandable Prefab House.
Designed with a steel structural frame,
insulated wall panels, durable flooring,
and an expandable building configuration,
this portable structure provides a
practical solution for customers
looking for additional space.
The expandable design makes this unit
suitable for a variety of potential
applications, including temporary
storage, construction-site facilities,
portable offices, and other
approved uses.
A Flexible Expandable Prefab Building
The Mobile Expandable Prefab House
16½ft × 20ft combines
portable construction with an
expandable structural design.
Its steel frame supports a building
system intended to simplify
transportation and on-site deployment.
Unlike conventional construction
projects that require extensive
on-site building work, this
prefabricated unit is designed
to be transported in a compact
configuration and expanded at
an appropriately prepared location.
The structure uses flame-retardant
foam wallboard, insulated roofing
materials, glass-magnesium flooring,
and double-layer tempered-glass
windows according to the
supplied specifications.
It can be considered for temporary
warehousing, portable workspaces,
construction support, or other
applications where the building’s
specifications and local regulations
are appropriate.
Residential use, permanent placement,
and occupancy may require additional
fit-out, permits, inspections,
and local approvals.
