This kit contains instructions and materials for building three different tiny houses, and a trailer base that can be used with each of the three houses. Each tiny house has unique roof, design and exterior features, including sliding doors, a deck, stairs, a gable, roof, and a pop out extension room. You will also learn to make interior walls, fixtures, and furniture for one house. Once you’ve learned the basics, you can branch out to designing and building your own tiny houses and furniture..
