Mysterious Building

Next door they seem to be constructing something very odd. We need your help, what is this building? Should we be worried?

Next door they seem to be constructing something strange.  We’re 50/50 split here on it being a launch pad  or a shelter for the zombie apocalypse.  The first picture is early construction, and the second is the most recent.  What do you think it is? :)
