Job-site container office: plans, paperwork, and tools in one delivery
If you're running a job longer than 60 days, a permanent office on site pays for itself fast. No more crawling into a pickup cab to sign paperwork in the rain. No more lost plans flapping off a folding table. $19,999 for the standard 20′ build — move-in ready the day it lands.
What contractors actually use them for
160 sq ft is enough for a 4′ x 8′ plan table, two chairs, and standing room for the foreman + a sub running a walk-through. Insulated walls keep it usable in January without a torpedo heater chewing up your day.
Steel fire door + deadbolt. Owner contracts, change orders, sub W-9s, and crew time sheets don't walk off the site overnight.
Add a $1,200 interior partition and we keep the original container rear-doors for exterior tool access. Office in front, locked tools in back, one trailer to mobilize.
220v Senville mini-split runs heat and AC. Iowa/Wisconsin winters and August humidity — the unit stays comfortable. Plug it into the temporary service on the pole and you're running.
Site requirements
What you need on site
- A level, firm pad — gravel, compacted base, or temporary mat all work
- A power source — 100A service from the temp pole, or a generator
- Tilt-bed truck access — driver needs maneuvering room to back the unit into place
- Phone signal or a hotspot if you need internet
What we handle
- Build the unit in Garnavillo IA — Taylor and crew
- Deliver and set on your pad
- Permits in jurisdictions that require them (separate quote)
- Pickup at end of project — separate quote based on distance
When it's the right call vs. renting a trailer
Job-site trailer rental in IA/WI runs $250–$450/month plus delivery. On a 12-month build that's $3,500–$5,500 with no equity at the end.
Container office at $19,999 owned: the break-even vs. trailer rental is roughly 4 years. But you can move it to the next job, sell it, or keep it on your yard as a permanent shop office. We see contractors buy one, run it across 3–4 builds over a decade, and still resell for $9k+.
If your build is shorter than 6 months and you don't have a next use, the trailer rental probably wins. If you're doing multi-month builds repeatedly, the math flips fast.
