The first room was launched for the planned human space complex that is planned to be accessible to the commercial sector by 2015. (link) Evidently, Bigelow Aeorspace began operations in 1999 and is mostly funded by its founder, Robert T. Bigelow, who has invested almost $75 million of his own money--about 95 percent of the total expenditures as of April 2006, and expects to spend up to $500 million from his own pocket to get his space complex off the ground by 2015. Bigelow hopes to recoup some of its costs by winning America's Space Prize of $50 million, which rewards the first private spacecraft to send a crew of at least five people on a journey of at least two orbits and return them safely back to Earth by January 10, 2010. (same type of concept at the X Prize)
"Bigelow plans to launch its space complex into orbit in sections that will be powered by large solar cells."
"While in orbit, the sections will inflate to their full size."
"The sections will be assembled into a space complex that will have room for rockets to dock and return to Earth."
"Here, this artist's model shows supply rockets on three sides of the space complex."
