Two footprints. Three levels of finish.
Every Casa 622 cabin starts as one-trip steel — a 20-foot box at 160 square feet, or a 40-foot high cube at 320 — framed and insulated in our shop in Goliad. What changes between the Sport, the Comfort and the Classic is how far we take it before it leaves the yard.
Which size are you building for?
The two lines are built the same way out of the same materials by the same crew. The question is how much room the use actually needs — and, usually, what the site and the budget will carry.
The 160 Series
From $16,900A 20-foot cabin with a sleeping area, a full bath and a kitchenette. Right for hunting camps, a guest room out back, and sites where you are placing several cabins rather than one.
The 320 Series
From $34,900A 40-foot high cube with room to live in full time — separate sleeping area, a real kitchen run, and the head height a high cube gives you. Our most-ordered line.
What every cabin has in common
A one-trip container — a box that has made a single ocean crossing, not a retired unit with twenty years of weather on it. We frame inside the corrugation, insulate the cavity, and leave it vented so the steel can dry.
- One-trip shell, factory finish or painted
- 2×4 framing on the walls — 2×6 on 24″ centers available
- Vented insulation cavity behind the interior panel
- Exterior electrical panel, ceiling light in every room, porch light at each door
- 240V range circuit and an exterior A/C disconnect for a future mini split
- Hot water on every model — a 30-gallon electric heater on the 320s, an outdoor propane tankless on the 160s
- Plumbing stubbed under the bath for your plumber to vent and tie into septic
Both lines run the same plan logic: kitchen at one end, bath at the other, sleeping area between. The 320 gets a partition wall and a full kitchen run; the 160 compresses the same three functions into 20 feet.
From deposit to delivery
Pick a model and a build slot
We build about four units a month. Slots are held with a deposit; payment is made in installments as the work goes.
Pre-orders go out
Container, insulation, doors and cabinets are ordered ahead. These items, plus the electrician's schedule, are what move a date.
Eight to ten weeks in the shop
Framing, insulation, electrical, interior, kitchen and bath. Our crew works the unit start to finish in Goliad.
Delivery and set
A third-party hauler brings it on an F-350 and tilt-bed trailer and sets it on the foundation you have ready, at grade.
Your electrician and plumber connect it
The cabin ships with the panel only — no cord, no feeder. Local trades make the final hookup to your service and septic.
Straight answers
The five we get most. There are two dozen more on the FAQ page, including insulation, ordinances, foundations and delivery access.
Do shipping container cabins sweat?
A steel box can, and we would rather say so. Every 320 is framed inside the corrugation with a vented cavity behind the panel, and our standard ceiling assembly puts a closed-cell spray foam flash against the steel with batt behind it — roughly R-25 — so the framing never presses on bare metal. The Sport ships with batt alone, which is an honest choice for a shaded site.
My city does not allow shipping containers.
Some municipalities prohibit them inside city limits. Where the ordinance is about appearance, wood or lap siding sometimes satisfies it; where it names intermodal containers directly, it will not. Call your building official before you place a deposit.
What do I have to do on my end?
A foundation the truck can reach at grade — piers with cement blocks and a metal tie-down work well — plus steps and a landing. Your electrician makes the final hookup to the panel; your plumber vents and ties the stub-out into septic.
How long is the wait?
Eight to ten weeks once the unit is in the shop. Pre-ordered materials and the electrician's calendar are what move a date, not the carpentry.
Is it a park model RV?
No. We are not pursuing park model RV certification right now — the engineering and recurring inspections would land on your invoice. These suit land where a structure or accessory-building permit is the path.
