Some University of Texas students are spending the night outside to raise money for Habitat for Humanity.
The students are also hoping to raise awareness of those who need a permanent home.
"What we're doing now is Shack-a-thon, it's a 24 sit in," said UT senior Anita Santpurkar. She is part of the campus chapter of Habitat for Humanity.
"People live in circumstances much worse than these shacks and we want to show what it would feel like a day living like this and raise awareness and what habitat can do."
This semester the Civil Engineering and Astronomy clubs are competing to build the best shack using only recycled materials.
Students walking by can vote for a dollar. Members of both organizations know they're making a difference.
About 300 students make up UT's Habitat for Humanity organization. They will roll up their sleeves this fall to help build 11 new homes in Austin.
The shacks will come down Saturday morning. However, for 24 hours they'll stand spreading hope and raising awareness for those who long for a permanent home.
