Quick Answer: Every growing market garden hits the same wall: harvest needs a wash-pack area and real cold, and barn renovations price like buildings. The container pattern: a 20ft wash-pack shell converted at our yard, paired with a reefer as the walk-in, totes rolling in at ground level. Van Blanc delivers both across Ontario from Brantford.

The Infrastructure Wall Every CSA Hits at Year Three
Ontario’s market-garden movement, the world EFAO’s membership has built plot by plot, follows a growth curve everyone in it recognizes. Year one washes carrots in a laundry tub. Year two adds a market stall and a borrowed fridge. Year three the CSA list crosses forty shares, and suddenly the operation needs what every food farm eventually needs: a real wash-pack area where harvest gets cleaned, sorted, and boxed out of the weather, and real cold that holds field heat back until delivery day. The traditional answer is a barn renovation priced like a building project, quoted in seasons the farm does not have, on a property that may be leased anyway.
The container pattern that small farms increasingly run instead: a converted 20ft as the wash-pack shell, a reefer beside it as the walk-in, both delivered on a truck, both movable if the lease ends, both owned instead of built.
The Wash-Pack Shell: What the Conversion Includes
The wash-pack container is a workflow room, and the build follows the workflow: wide openings at both ends where our shop cuts them, harvest totes in one door and packed boxes out the other; a washdown-friendly interior with sealed sheathing; drainage-conscious floor treatment sloped to where your site plan wants water to leave; screened ventilation because a wash room breathes or it molds; and shade-side placement in the site plan, because nobody sorts greens in a hot box. Work tables, spray bars, and the barrel washer are your equipment on our floor. The shell arrives from Brantford converted and ready for the trades’ finishing touch, which gets its own honest section below.
The Two-Door Line
The layout the efficient farms converge on: field door, wash station, sorting table, pack station, cold-room door, in one straight line. Twenty feet is exactly enough for one person’s harvest morning to flow without a single backtrack, which is the entire point of a wash-pack.
The Cold Half: Pairing the Reefer Walk-In
Field heat is the enemy of everything a market garden sells, and the reefer container is the walk-in cooler that arrives on a truck: electric, quiet, ground-level, and sized so a week’s harvest plus the CSA staging wall fits with room to walk. The full comparison against rented refrigerated trailers lives in our reefer guide; the farm-specific summary is that the reefer plugs into the same service your electrician runs for the wash-pack, holds whatever setpoint your crops want, and doubles as the farmers-market staging cooler on Friday nights. Farms watching budget start with the wash-pack shell and a used commercial fridge, then add the reefer the season the CSA list makes it inevitable, which is usually one season.
Christian LeBlanc, second-generation operator: “A forty-share CSA east of Brantford ran their wash-pack container’s first season with the barrel washer inside and the packed shares staged on a wall of labelled shelves. The farmer told me Thursday nights went from four hours in a hot barn to ninety minutes in a room built for exactly one job. The reefer came the next spring, the week her list hit seventy.”
Thursday Night: The CSA Staging Wall
Every CSA lives and dies on distribution night, and the staging wall is the container’s quiet second job: shelving down one side where packed shares wait in member order, pickup lists taped at eye level, and the whole night reduced to members walking a line. Farms running multiple drop sites stage by route, coolers loaded in reverse-stop order from the reefer. None of this is complicated, which is the point; the box’s gift to a farm is boring reliability during the eighteen weeks a season when nothing is allowed to go wrong.
Who Builds What: Our Shop, Your Plumber
The split, stated the way we state it on every build: our Brantford shop delivers the converted shell, openings, sheathing, drainage-conscious floor, vents, and the electrical rough-in. Water supply, drain connections, and the final electrical hookup are completed on site by your licensed trades, and food-safety practice for your operation, wash-water standards included, belongs to your own program and your local health unit’s guidance; farms marketing under CanadaGAP run their storage and wash practice to that program’s requirements, and the container simply becomes the room those requirements live in. We build the vessel honestly and leave the certifications where they belong, with the people licensed to give them.
Harvest Season Does Not Wait for a Barn Reno
Describe the operation, shares, market days, and the field door’s compass direction, and the wash-pack spec comes back the same day, reefer pairing included if the list is ready for it.
Winter and the Off-Season Shell
From November to April the wash-pack shell earns its keep as every other page on this site would predict: the market stall, tents, and tables winter inside; the irrigation headers and row cover come in off the field; and the seed order stages on the staging wall in February. The reefer, setpoint raised, becomes the root-crop hold that stretches storage-crop sales into winter markets, the same pattern our root cellar guide explores from the homestead side. Two boxes, twelve months of jobs, zero seasons of rent.
Wash-pack setups run from lean-tos to reefers. See the field guide to your other options for the field.
Market gardeners adding a winter crop should also see the microgreens vertical-farm shell, which grows year-round from the same yard.
Frequently Asked Questions
What does a container wash-pack conversion include?
Openings cut for the two-door workflow, washdown-friendly sealed sheathing, drainage-conscious floor treatment, screened vents, and an electrical rough-in, converted at our Brantford shop before delivery. Your trades connect water, drains, and final power on site.
Can a reefer container work as a farm walk-in cooler?
That is its natural second career: electric, quiet, ground-level for totes, and holding whatever setpoint your crops want. Most CSAs add it the season their share list makes field heat a real enemy, and it doubles as the market staging cooler.
What about food safety requirements?
Your operation’s own program governs practice, CanadaGAP for farms marketing under it, and your local health unit’s guidance for the rest; one call to them sits beside the call to us. We build the room honestly; the certifications belong to the people licensed to give them.
Does this work on leased land?
Better than anything else does: both boxes arrive on a truck and leave on one, which is exactly the infrastructure a leased farm should own. If the lease ends, the wash-pack and the walk-in move to the next field with you.
What happens to the wash-pack in winter?
It becomes the farm’s off-season vault: market stall and tents inside, irrigation off the field, seed order staged in February, and the reefer at a raised setpoint holding storage crops for winter markets. Two boxes, twelve months of work.
