Finished Prefab Homes vs. Kits vs. Shells: Which Is the Smartest Buy?
Three ways to buy a prefab home. Three very different price tags. One big opportunity to save serious money.

The Finished Prefab Home
A factory may install bathrooms, kitchens, windows, insulation, and interior finishes before shipping. That can reduce on-site work and improve consistency. But factory-finished doesn't mean move-in ready in America. Foundations, utilities, approvals, and modifications may still be needed.
The Expandable Home
Some homes fold down for transportation and expand on-site. Shipping efficiency can be a major advantage, and modern designs offer attractive options. But unfolding connections, waterproofing, insulation, structural performance, and local approvals need careful evaluation. Expandable doesn't mean exempt from building codes.
The Structural Shell
What if the factory builds the bones and American tradespeople finish the interior? A shell may provide framing, walls, roof, windows, doors, or insulation, depending on the package. Buyers can choose local electrical, plumbing, HVAC, kitchen, and finishes. But local labor and construction management add costs, and an unfinished shell isn't automatically easier to import or approve.
The Kit Home
Kit homes arrive as components assembled on-site. Packages range from basic framing to relatively comprehensive systems. They offer flexibility, but labor, equipment, missing materials, inspections, and site work can add up. Some assembly required — and we're not talking about a bookshelf.
Compare the Options
- Finished prefab: more factory work, but shipping and site connections remain.
- Expandable home: compact shipping, but careful evaluation of expansion systems.
- Structural shell: local finishing flexibility, but more domestic labor.
- Kit home: customization, but assembly complexity and project management.
Field House is building a Rolodex of manufacturers and qualified service providers to help buyers identify who they may need at each stage. Buyers remain responsible for verifying credentials, terms, and project approvals.
Quality Is the Game Changer
We want documented framing, insulation, windows, weatherproofing, testing, factory controls, and warranty terms. The goal is not merely inexpensive buildings. It's strong design and construction quality at a competitive overall price.
The Real Cost Is the Finished Cost
Compare factory price, included features, freight, duties, engineering, permits, foundations, local labor, utilities, finishing, and warranty support. A $15,000 finished unit might beat a $9,000 shell — or the shell could win. The numbers decide, not the advertisements.
Where Field House Comes In
We're exploring finished cabins, expandable homes, shells, and kits so buyers can choose the right approach for their property, budget, and intended use. More house. More choices. Better value.
