Top 5 Modular & Prefab Home Builders in Wisconsin | 2023 List

Although modular and prefab homes are becoming more popular, they are still not as popular as traditional homes. This can be an issue because you might have a hard time looking for a local builder to help you. Finding a reliable supplier to supply you with your prefab or modular home is also challenging. This article will share valuable information on some of the most trusted builders and suppliers who can help you build your prefab home. 

Why Build a Prefab or Modular Home in Wisconsin?

Building a modular home in Wisconsin is excellent if you are pressed for time since a prefab home is faster to build than conventional houses. It is also cheaper to build, hence saving you much-needed dollars.


One of the downsides of modular homes is that you’ll have limited options for customization. You’ll be able to pick the color, finishing materials, doors, and windows, but you’ll have a limited selection regarding the size and shape of a prefab home. 

This leads to another disadvantage: modular homes can be difficult to sell because more people still prefer conventional houses.
