Cost Of Material For Building a Tiny House

One of the huge factors of any house building is the material you will choose for it. 

Here you need to remember that every aspect of the tiny house can be bought separately.

This allows you to have more options for your house-building project. When you break down the house into different parts, you will make it more manageable and figure out its cost in the end.

Most of the budget will go towards the trailer, door, windows, roof, and mechanical. Most people might skip on these elements to save some money, but getting the best of each one for your project is better. Most of the cost will come from trailers, doors, roofs, and mechanical elements of the house.

You can save money on trailers by getting a used one, but only if you have experience with metalworking. See our article ( how much does a welder cost?)

The trailer will need its fair share of fixes, repairs, reinforcements, and a new paint job if you don’t have any. If you count the cost of all of them, it will reach the level of a new trailer or might even break that threshold.

Windows/Door Cost

The window will cost around $120 for a pre-designed model when it comes to windows. But if you want to switch up to a more customized look on the house, the cost will reach up to $250 to $300.

Doors are exceedingly accurate; many here hire a door manufacturer to build a door that meets your needs. A self-built door can cost $500, a basic manufactured door can cost up to $800, and lastly, a high-end manufactured door can cost around $1,500.

Should You Build Your Own Tiny House?

Most of the cost for building a tiny house will come from labor rather than material. The percentage of the budget is set at 50 to 60%, which will go towards the labor required for the building project.

You need to double the amount for a tiny house project to add the builder to work. If the house costs $10,000 in materials, you will need to set the budget at $20,000 to $25,000 from a builder. If the home requires $30,000 worth of material, then from a builder, the price will be set at $60,000 to $70,000.

If you can build it yourself, you will save plenty of money, but you will have to put in a lot of effort in making one in your backyard. According to people who have built a house in the backyard, the work is pretty simple and doable. This option provides the best budget options to the owner.


The prices here will differ depending on the route chosen by the owner. If the owner decides to build a house all by themselves without labor, the cost will be cut in half. If they choose to the labor/builder route, then the price will double, but that will also result in the owner putting no effort into building the project. Many people who have a tiny house in the backyard recommend you to put the time and effort into building the house rather than choosing the alternative.
