On any given night in the United States, there are over 600,000 homeless people on the street. While this is already an alarming statistic on it’s own, violence against the homeless has risen by a whopping 24% since 2013. Homeless Americans are not only living in poverty, but risking their lives every night on the street. Artist Gregory Kloehn of Oakland, California took note, and decided to take matters into his own hands. Kloehn makes homes out of materials that have been thrown away, varying from scrap metal, to car parts, to furniture. Kloehn scours the streets of Oakland to find washing machines, refrigerators, and other illegally discarded trash that he can use for the houses.

Earlier this year we featured Kloehn’s selfless work, but his tiny houses barely scratch the surface of how he upcycles discarded items. Kloehn also refurbishes bikes for the homeless, adding practical items onto the modes of transportation. He’s also built living spaces out of storage units and dumpsters. Check out more of his amazing work below.

Here are four new houses Kloehn made this past summer.

This house has a tiny deck and a grill attached for cooking.

This house is equipped with solar panels. The shopping cart bike provides the homeless with a method of transportation and storage.

This bike has a tiny stove attached to the front, a fire extinguisher for safety, and storage for food in the back.

Not only does this tandem bike have a grill, there’s also a water reservoir and a working hose.

Here’s another water-equipped bicycle.

Kloehn turned this dumpster into a functioning living space.

Kloehn also builds homes out of shipping containers.

The inside of the house features a couch…

…that folds out into a bed.

There’s plenty of storage space inside, including room for musical instruments.

Here’s the bathroom in the container house.

From stationery, living like a storage container, to more mobile options, like a bike or a house on wheels, Kloehn is in the selfless business of helping those who need it the most. It’s truly amazing. You can follow Gregory on Facebook, as well as on the Homeless Homes Project‘s page. See more of his work here.
