about the homeless helper

I read the article about the boy who made the dome home thing for homeless people.It's pretty nice but they didn't mention if homeless people are suppose to make it themselves or the boy makes them and then hands them out. I wonder only because theres a picture of the boy in a metal shop and if the homeless are suppose to make this themselves it may be hard for them to get access to a metal shop...but it was still a nice thing ..I'm just being a jerk
