Building a Two-Story Addition onto a Manufactured Home
This single wide didn’t stay single for long. It didn’t stay single story for long, either. See how one tenacious couple created their dream home by building a two-story addition onto a manufactured home.
Meet the Arledge’s
Jessica and her husband live in Polk County, NC and wanted to live completely debt-free. Their plan was fairly simple: buy a single wide, live in it, and pay it off as quickly as possible. Once their budget allowed, begin buying materials and start building an addition onto the manufactured home (while still living in the single wide) and that’s exactly what they did! The results are pretty awe-inspiring.
Living debt-free is a goal for many of us but obtaining a debt-free lifestyle is no easy task. That’s why manufactured homes of all ages and sizes are becoming more popular. They provide a stylish home with unlimited potential at half the cost per square foot of a site-built home.
The original 2010 Horton single wide:
Building a Two-Story Addition onto a Manufactured Home
In 2011, Jessica and her husband began the first step toward their debt-free dream by purchasing a 2010 model Horton single wide that was 14′ wide and 60′ long. The home had 2 bedrooms and one bath.
With two adults and three children living in 840 square feet can get a little cramped. It doesn’t matter how organized you are or how much storage you can create. They knew they needed a larger home and after considering all their options they decided that building a two-story addition onto a manufactured home would give them their dream home while still becoming debt-free.
The Arledge’s ultimately planned for a full two-story addition onto a manufactured home. This would give them two more bedrooms, a large living room, another full bath, and a full basement within a 16′ by 60′ shell.
They would combine the single wide and the addition by opening up sections of the single wide’s exterior side wall, aptly called the marriage line. Together with the single wide the family would end up with 1,800 square foot of heated living space.

DIY Makes a Huge Difference when Building a Two-Story Addition onto a Manufactured Home
Doing most of the labor yourself will save you a ton of money. Of course, you will still need licensed professionals to pass inspections such as electricity and plumbing.
Materials were the Arledge’s major expense because they did all of the labor themselves with a little help from friends and family. They were able to use a lot of block and wood they salvaged over the years, too.
In all, Jessica estimates that the total cost for their two-story addition onto a manufactured home was between $17,000 and $24,000. That addition gave them 980 square feet of heated living space. That is a huge difference!

Installing a Basement Under a Manufactured Home? Oh, Yeah!
We’ve seen several manufactured homes placed over a basement but we’ve never seen it done quite like this!
Adding a manufactured home over a full basement is becoming more popular now that new tools and technologies have made it easier to move a manufactured home horizontally.
In Jessica’s case, they were creating a basement under their single wide. Literally.
This was no simple task. Making sure a manufactured home is level and has strong supports is critical. Jessica admitted this was the couple’s biggest challenge and in the end it became their proudest DIY moment.
Jessica said her husband was thrilled to get the basement dug out and the concrete walls poured all while keeping the home level and balanced.
Adding an Addition to your House: Interior Progression
The family continued to live in their single wide while building the two-story addition onto their manufactured home. Here you can see how the addition was constructed and framed out as a completely separate structure from the single wide.
On the left you can see the single wide. The area with the window and the thermo wrap will become the marriage line, where the exterior wall is removed to combine the addition and the manufactured home.
Cutting out sections of the perimeter walls, while being careful to keep the structural integrity of the home, allowed for a large open floor plan.
Like many of us, Jessica wanted her dream home to have Hardie board and batten. Installing the boards vertically creates a visual that works great for manufactured homes with low ceiling and roofs. I hope to put Hardie board on my own single wide soon.
Painting the home and the addition a darker color gives it stature against the mountains and trees. You want a home in the woods to be grounded but not lost against the forest.
You would never know this home is 1800 square feet from the front. It’s another great example why you shouldn’t judge a book by its cover.
The talented and tenacious couple learned a lot about being patient and having a good work ethic in order to get the job completed. You can’t build a manufactured home addition in a week, especially when you have jobs and family. It definitely turned out great!
We asked Jessica if she had any advice for others wanting to buy a manufactured home and live debt-free. She encourages everyone thinking of buying and living in a mobile home to go for it. It’s a great way to live debt-free in no time!
