The ultimate rooftop swimming pool is at an apartment building in Houston.
Residents of Market Square Tower not only have a pool 40 stories above the city. The pool also extends ten feet past the end of the rooftop, with a clear Plexiglas bottom to let you see the street below.
Would you feel comfortable taking a dip (hopefully, not a dip that goes all the way down!)?
BTW, the building also includes a basketball court, movie theater and a sports room with simulated golf.
