On Wednesday, the Astrodome Conservancy unveiled their plans for the future of the Astrodome. The plan will reportedly cost $1 billion to build four "state-of-the-art" buildings under the Astrodome's roof with a "retail village.

The Houston Astrodome has been in limbo, waiting for its chance at a second life since being shuttered more than 15 years ago.

The Astrodome Conservancy is hoping a new $1 billion vision to redevelop the retired ballpark will spark interest in preserving the Houston landmark. State of play: The Astrodome has been largely vacant since 2002 and was deemed noncompliant with the Houston fire code in 2008.
