How do you add a room to a mobile home?

You may want to add a room to your manufactured home for a variety of reasons.

  • space
  • aesthetics
  • decrease expenses
  • add value to the mobile home


You don’t want to skip the outer appearance when you’re looking to do some upgrades to your mobile home.

A deck adds a living area that friends and families can enjoy year-round.


  • Decks come in all sizes and styles.
  • Super affordable mobile home add-on.
  • You don’t have to tear anything down (or match the foundation type) to build it.
  • Add instant value to a mobile home.


A sunroom makes for a beautiful mobile home addition if you want something a bit more closed in than a deck or porch.

A sunroom has a ceiling and walls but also has windows and skylights to give the perception that you’re outside without being subjected to the weather.

Patio Cover

While not quite a deck, a patio cover made from quality materials still adds value to a manufactured home.

You do need to check and make sure that support posts are firm. 


  • A covered patio proves a cool chill-out space.
  • Adding a patio cover sometimes adds more value than the additional costs.
  • It doesn’t require a huge building project.

Can you add an extension to a mobile home?

Of course, you can extend your mobile home. Families grow, circumstances change, and a single-wide is no longer enough to meet all of your needs.

Most of the time, mobile home additions and upgrades are more affordable than reselling and buying a double or triple-wide – just check with your park if you rent a lot.

Storage Room

It’s too easy to run out of room, and off-site storage has gotten insanely expensive.

Adding a storage room is a simple way to give yourself more space without building a whole new room and destroying the budget.

  • under-bed storage
  • install hooks
  • storage shed
  • shelves
  • storage ottomans
  • quality cabinet space


Garages are a multi-purpose mobile home add-on. 

You can park your vehicle under the safety of the cover and add an additional storage place at the same time.

Guest Room

A lot of the single-wide models only have one bedroom. But, even with two, you might still need extra space for visitors and relatives.

The biggest drawback of adding a guest room is that it’s expensive and time-consuming.


  • Adding a guest room provides everyone with more privacy.
  • It provides additional comfort and space without investing in a double or triple-wide mobile home.


It doesn’t seem like a huge deal, but having the right energy efficiency can create space without spending big money.

When you replace old windows, it’s an instant aesthetic upgrade.

Energy-efficient windows block heat in the summer and trap heat in the frigid winter. That means you’ll see an instant change in your electricity bill.

Extra Bathroom

If there’s a queue to use the bathroom, you should consider it one of the first additions.

Adding an extra bathroom isn’t a cheap or quick upgrade, even if you’re only building a half bathroom.

But, it’s well worth it for a growing family or for those that have regular houseguests.

How do you add an extra bedroom to a mobile home?

We’ll give you the basic steps to add an extra bedroom to a mobile home. 

Step 1

You have some initial decisions to make.

  • What do you want in the room? What’s its goal?
  • What color are you going with for your mobile home addition? (the fun part!)
  • What materials do you plan to use?
  • Do you have to install heat and air?
  • What about electrical outlets?
  • Don’t forget the windows.

Step 2

You’re looking for someone that has experience with building add-ons for manufactured homes. 

It’s going to require a little research, including whether or not they provide free quotes.

Step 3

Take a ton of pictures to provide for the builder if they aren’t coming to the site. 

You must communicate every aspect of the addition (consider legal issues like watching for the data plate, etc). And there’s never a dumb question. You’re the one paying for the service.

Step 4

Maybe after consulting a professional or two, you’ve decided you have the tools and skills to build the addition yourself.

You likely need to get some outside help installing heat and air and the possible plumbing.

Step 5

Don’t forget the roof (if it requires it). It’s one of the more accessible aspects of mobile home upgrades if you install it correctly.

Step 6 

Watch your add-on room come to life. You finally get to lay the floor or carpet and paint your walls.
