About Boxwell 8x20 Relocatable Self-Storage Units

DRIVE-UP STORAGE, SIMPLIFIED.

Boxwell relocatable storage units give self-storage operators a durable, scalable alternative to traditional construction. Engineered for long-term outdoor use, they deliver the strength and aesthetics of permanent buildings with the flexibility of relocatable infrastructure.

WHERE BUILDINGS FLOP, WE FLOURISH. 

Relocatable storage units are the most flexible outdoor self-storage solution available. Without the need for permanent foundations or traditional construction, they work in areas where standard buildings are restricted, impractical, or cost-prohibitive.

Boxwell relocatable units flip site perimeters, fence lines, parking lots, setbacks, easements, and vacant areas into profitable storage. Their standalone design allows operators to transform underutilized land into revenue-generating storage space. Low minimum order quantities provide the flexibility to scale over time while refining placement, layout, and unit mix along the way.

NO LIGHTWEIGHT SHORTCUTS.

Unlike competitors, Boxwell does not build a lighter-duty version for self-storage applications. Every self-storage unit is engineered with the same heavy-duty steel construction and structural integrity as our transport-ready portable containers — resulting in a stronger, longer-lasting storage solution built for real-world demands.
