What is a modular home?
The short version: a real house, built indoors in sections, delivered to your land, and set on a permanent foundation.
What is a modular home?
A modular home is a house built indoors as complete three-dimensional sections called modules, each finished with wiring, plumbing, insulation, and interiors before leaving the factory. The modules are trucked to your site, set on a permanent foundation by crane, and joined into one house built to the Ontario Building Code.
The only fundamental difference from a conventional house is where the work happens. Framing, mechanical rough-ins, and finishing all take place at fixed factory stations instead of on an open lot, which is why the modular process runs on a schedule northern weather cannot touch.
What is the difference between modular, mobile, and manufactured homes?
A modular home is built to the same Ontario Building Code as a site-built house and sits permanently on a foundation. Mobile and manufactured homes are built to the separate CSA Z240 standard, keep a steel chassis, and are treated differently for financing and resale.
This distinction matters most at the bank and at resale: a modular home is appraised and mortgaged as ordinary real estate. If a listing mentions Z240 or a chassis, it is not a modular home in the building-code sense.
How is a modular home built?
At ModBox the build runs through six stages over roughly 24 to 26 weeks: consultation, design, production planning, factory fabrication, delivery, and on-site completion. Fabrication itself takes about 12 weeks, and site work after delivery is measured in days.
Because modules must survive highway transport and a crane set, they are engineered stiffer than conventional framing. Our lines cover wood modular homes, light steel frame homes, and custom builds, from compact studios to four-bedroom family homes.
Why does modular make sense in Northern Ontario specifically?
Because the region's two hardest constraints, a short outdoor building season and long distances between sites and trades, are exactly what factory construction removes. Production continues through winter, and a nearly finished home travels to the site once instead of dozens of trade trips travelling to it.
That is also why modular is often the only practical way to build well in remote and fly-in communities. ModBox has delivered 24 projects with First Nations across the region, moving modules by highway, winter ice road, and barge.

Modular home basics: common questions
Is a modular home a prefab home?
Yes, modular is one kind of prefab. Prefab covers anything partly built off site, including panelized walls and kit homes. Modular means whole three-dimensional sections arrive finished inside and out, which is the most complete form of prefab construction.
How long does a modular home last?
As long as any well-built house. A modular home is built to the Ontario Building Code on a permanent foundation, and its factory-built structure is engineered to survive highway transport, which demands more rigidity than a house that never moves.
Do modular homes look like regular houses?
Yes. Once set and finished, a modular home reads as a conventional house inside and out. Rooflines, siding, kitchens, and finishes are chosen the same way as any custom build.
Can modular homes have basements?
Yes. Modules are set on whatever engineered foundation the site calls for, including full basements, crawl spaces, or screw piles on rock and remote sites.
Who builds modular homes in Northern Ontario?
ModBox NWO Inc. builds modular homes in a 25,000 sq ft Thunder Bay facility and delivers across Northwestern Ontario, including remote First Nations communities reached by winter road or barge.
