20 Free DIY Tiny House Plans to Help You Live the Happy Life

20 Free DIY Tiny House Plans to Help You Live the Happy Life

tiny house plans

Have you heard of the tiny house movement?

Of course, you have. The idea is spreading like wildfire. More and more people are selling their large normal sized homes and in turn building houses that are about a third of the size of the original house.

Imagine living in a house that is about 8.2x23ft. It sounds crazy but the amounts of cash saved makes the change bearable and worth it.

Part of the saving comes from the fact that these houses can be turned into DIY projects. Speaking of which, I have compiled a list of small house plans you can choose from.

Hopefully, they will inspire you to embark on a DIY project.

If you like these free tiny house plans, you may also like ones for building a camper trailer, gazebo, deck

While the tiny house movement has grown in popularity over the past couple of years, people still know very little about them. Actually, most do not realize they can build their own tiny house.

But if you have and want to start on one, below are some things you should know and do.

1. Have a Budget from the Get-Go

Tiny houses are not expensive, but they can be. To keep yourself from overspending, you will have to set a strict budget from the start.

Some individuals have built tiny houses for a few hundred dollars to $40,000 even. Without parameters to guide your spending, there is no telling how high the costs may go.

Before you commence on the tiny house, you should have the design of the house in mind, know the materials to be used and how much each material will cost.

It is after asking and answering these questions that you embark on online research to determine the cost estimate. To the cost of every material, remember to add about 15 % cushioning.

2. Determine a Place to Call Home

Before you embark on the project, have a predetermined spot where it will stand. Given that it sports wheels does not mean you will drag it all over the country.

It would be best if you build the tiny house close to a hardware store. This proximity will save you time from the inevitable trips to the hardware store.

3. Consider Insurance

A common misconception about tiny houses is that they do not need insurance. Well, if your tiny house will be permanently installed on your land, you will need to pay a home insurance policy.

On the flip side, if it is built with wheels, things get a little bit tricky. For such tiny house designs, you might have to consider different options.

If you intend to move the tiny house only once a year, you could cover it with the stationary trailer insurance policy.

However, if you will move more than once a year, then you should get the travel trailer insurance policy.

4. Think About Layout and Size

It is so easy to lose sight of the goal and purpose when building a tiny house. When planning, lots of things may pop up and seem like essentials and must-haves.

But remember, too many of these will beat the whole point of having a tiny house. Instead of seeing it as sacrificing, look at it from the perspective of how much it will allow you to get done.

5. Rent Before Building

It is important to take a new car out for a test drive before buying it. The same way, before you decide to build a tiny house, ensure you have been in one.

Feel what it is like to live in a tiny house before investing your time and money in one. Good thing there are lots of tiny houses up for rent.

It is as such a matter of picking one that resembles your tiny house design in layout and size.
