Used ISO container versus purpose-built office shell
A retired 20ft shipping container starts at around ₹1.45 lakh in the Chennai port belt. A purpose-built container office shell — same external dimensions but with proper cut-outs for windows, an insulated roof and an internal frame to take partition walls — starts at around ₹2.85 lakh from our Krishnagiri factory.
Both can be turned into an office. The used container will always look slightly uneven inside because the corrugated walls are part of its structural strength and cannot be fully flattened. The purpose-built shell has flush interior walls because the structure is in the steel frame, not the skin. Choose based on how the office will be used, not on the per-square-foot rate.
