These beautiful tiny homes cost less than $20,000 to build - take a look inside

A team of architecture students designed a seemingly impossible home.

After more than a decade of designing, editing, and reworking, the students at $4 - Auburn University 's architectural-design program - built two cottages in 2016 with raw materials that cost just $14,000 each. (The team calls them the "$4.")

The goal was to create a model for building homes that are both beautiful and affordable.

In late summer 2017, Rural Studio will begin planning two more homes with materials that cost even less than $14,000. The students expects to start construction in early 2018.

Take a look inside the first two homes.
