A standard walk-in stops at 8 or 10 feet. A warehouse room is built to the height of your pallet racking, so the cubic footage you pay to refrigerate is footage you can actually store in. The Atlas Foods cooler and freezer both run 20 ft tall.
Market / Warehousing & Distribution
Cold storage warehouse construction in Ontario.
A cold storage warehouse is built around pallets, clear height and forklift traffic, not shelves. WFE builds racked coolers and freezers inside Ontario warehouses and distribution centres, from 500 to 10,000 sq ft, with our own crew from layout to commissioning. At Atlas Foods in Toronto we took an empty warehouse bay to a working 20 ft cooler and freezer in under 30 days.
Fig. 01 · What you actually buy
A cold room built
around your racks.
A warehouse room has to hold tall pallet racking, take forklift traffic every hour, and keep the top pallet as cold as the bottom one.
This is where most of these builds start: an empty bay.
Atlas Foods handed us an empty Toronto warehouse bay. Under 30 days later it was a 3,000 sq ft cooler and a 1,000 sq ft freezer, racked and holding product. Panels, doors, refrigeration and commissioning ran with one crew on one schedule.
Tall racked rooms stratify: warm air sits at the top pallet while the thermostat reads fine at eye level. We place multi-fan ceiling evaporators over the aisles so air moves through the racks, and size the plant with margin for loading-dock door cycles.
Warehouse rooms get wide sliding insulated doors that clear a loaded forklift, man doors for people, and steel bollards where equipment turns. At SKOR Crestlawn we fitted two automatic sliding doors and bollards on a 3,000 sq ft freezer.

Atlas Foods: an empty warehouse to 4,000 sq ft of cold storage in under 30 days.
- Cooler: 3,000 sq ft, 20 ft tall, racked for pallets.
- Freezer: 1,000 sq ft, also 20 ft tall.
- Refrigeration: Trenton, SmartRefer and Heatcraft equipment on multi-fan ceiling evaporators.
- Timeline: empty Toronto warehouse bay to operational in under 30 days.
Larger scale: the Halal Meat upgrade covered a 10,000 sq ft freezer and a freezer floor rebuild, and Pacer Air Freight is 6,000 sq ft inside an operating facility.

Deep Dive
More on refrigerated warehouse design & construction.
Expand any section for the detail on building inside an existing warehouse, racking and airflow, freezer floors, doors and docks, multi-zone builds, and owning vs renting cold storage.
Cold Storage Warehouse Construction Inside an Existing Building
Most of the warehouse cold storage WFE builds goes inside a building that already exists: an empty bay, a leased unit, or part of an operating distribution centre. The insulated envelope is framed inside the shell, panels are cut to fit around columns and sprinklers, and the building keeps working around the build. Atlas Foods went from an empty Toronto bay to a racked cooler and freezer in under 30 days; Pacer Air Freight was built inside an operating air-freight facility in Mississauga.
Refrigerated Warehouse Design: Height, Racking and Airflow
A refrigerated warehouse is designed from the rack plan outward. The rack height sets the wall height, the aisle widths set the door widths, and the evaporator positions follow the aisles so cold air reaches the top pallet, not just the thermostat. We size the refrigeration for the full cubic volume and for how often the dock doors open, not for the floor area alone.
Freezer Floors and Frost Heave
A freezer built on a bare slab slowly freezes the ground underneath it, and freezing ground can lift and crack the floor. Warehouse freezer zones get an insulated floor system so the slab below stays above freezing, finished with a ramp or a flush transition at the door so forklifts roll straight in. On the Halal Meat build WFE rebuilt the freezer floor as part of a 10,000 sq ft freezer and 3,000 sq ft cooler upgrade.
Doors, Docks and Forklift Traffic
Doors take more abuse in a warehouse than anywhere else in a cold room. Wide insulated sliding doors clear a loaded forklift, man doors keep foot traffic from opening the big door, and steel bollards protect panels and door frames where equipment turns. The SKOR Crestlawn freezer runs two automatic sliding doors with bollards for exactly this reason.
Cooler, Freezer and Multi-Zone Warehouse Builds
Distribution operations rarely hold one temperature. A typical build pairs a racked cooler with a freezer zone in one envelope, each with its own refrigeration and set-point, and adds a controlled room or staging area where product needs it. For single rooms without racking, see custom cold storage; for frozen-only builds, see walk-in freezers.
Building Your Own Cold Storage vs Renting 3PL Space
Renting pallet positions in a public cold storage warehouse makes sense for seasonal or uncertain volume. Once you are paying for the same pallet positions every month, a room in your own building usually costs less over its life and puts the product next to your trucks and your staff. WFE builds the room; we do not operate public cold storage or rent space.
