About this video: a 108,000 sq ft mushroom warehouse steel building
This mushroom warehouse steel building video tours a 108,000 sq ft facility Toro Steel Buildings provided for a Canadian mushroom farm. Drone footage and walkthroughs show the main warehouse, a 20,000 sq ft clear-span auxiliary building and the growing rooms inside.
The farm needed a high-performance building for growing and distributing mushrooms. The main warehouse has a standing seam metal roof for a leak-resistant seal, and the envelope uses R40 Energy Saver insulation with R24 insulated metal wall panels to help keep conditions steady for sensitive indoor crops.
- Large-scale agriculture. A 108,000 sq ft main warehouse laid out for growing and distribution.
- Open, flexible space. A 20,000 sq ft clear-span auxiliary building with no interior columns.
- Built for climate control. R40 insulation, R24 IMP wall panels, and a project completed on schedule.

Questions about the mushroom warehouse
Planning an agricultural building? Price your building and a building specialist will walk you through it.
How big is the mushroom warehouse?
The main warehouse is 108,000 square feet, built for a Canadian mushroom farm. A separate 20,000 sq ft auxiliary building sits on the same site.
What does clear span mean?
A clear-span building has no interior columns, so the whole floor is open. The 20,000 sq ft auxiliary building is clear span, which gives the farm full flexibility in how it lays out the space.
How is the building insulated?
The video lists R40 Energy Saver insulation and R24 insulated metal (IMP) wall panels. According to the YouTube description, the main warehouse also has a standing seam metal roof for a leak-resistant seal.
Why use a steel building for indoor farming?
Indoor crops like mushrooms need a controlled climate. A well-insulated steel building with a tight roof and wall envelope helps keep conditions steady, and large clear spans leave room for growing rooms and equipment.
Was the project finished on time?
Yes. The video notes the facility was completed on schedule.
What else can a building like this be used for?
The same approach works for growth facilities, warehouses and distribution centers. Toro designs each building around the use, the site's loads and local codes.
Does Toro supply the foundation?
No. Toro provides the structural reactions for every building so a local contractor can build the foundation to spec. You also get engineer-stamped drawings for your location to use for your building permit.
