OAKLAND - An artist in Oakland, California, is using his skills to help the homeless by building small enclosures that serve as portable homes and offer safety and protection from the elements. 

An industrial section of West Oakland, beneath freeway overpasses, is dotted with tiny houses designed and built by a local artist. Some are little more than one meter wide and several meters long, but come complete with doors and windows.  Greg Kloehn has built and given away at least 20 of the structures.

Several are on the roadside near where freight trains pass.  The artist stops by to visit and a formerly homeless man named Oscar Young embraces him outside Young's small residence.

“I like to help them," Kloehn said. "Sure. I mean, it is fun for me.  I like to make things, and to do something that makes a big impact on someone's life is good.”

Inside the enclosure, Young gets relief from chilly nights on the street.

“Well, it is better than living on the ground, to tell you the truth, because if it was not for Greg, I would be still on the ground,” he said.

The artist visits a another friend called Sweet-pea, who lives in one of the houses.  In it she keeps herself safe and protects her belongings.

Mornings, Kloehn scours the streets for construction materials, which are dumped illegally at night.  He brings them to his studio, where he puts the homes together.

“I mean, I have been in the middle of the building process, run out of materials, gotten in my truck drove around to look for something," he said. "That is my shopping.”

A discarded cabinet door makes a window cover.  Shipping pallets become the walls of the structure. He has installed a small electrical unit powered by a solar cell, mounted on the roof.

“I put it on a light, an old lamp, so you could move it around," he said. "You could keep it optimum to the sun.”

Empty coffee bags become shingles and a washing machine door and refrigerator shelf become windows. Nails, screws and glue hold it all together.

“I call them the fruits of the urban jungle," he said. "Here is what is dropping. Here are these natural resources that we can use.”

Some on the streets once had houses of their own, but Sheila Williams has learned to live with less.  She settles into a cushioned easy chair, sitting in the open outside her small home.

“I had it all just like you people do out there.  But look at me now," she said.  "I have been living in one of Greg's houses, and I am thankful to that man.”

The residents have collected discarded wood and other material for Kloehn's newest shelters.  Williams hands him a framed picture of flowers that looks nearly new, another discard found on the side of the road.

“When I finish the homes off, sometimes they come with artwork, everything installed,” Kloehn said.

The artist says this is not a social project, just someone using his skills to help his homeless neighbors.
