The master bedroom boasts an integrated TV that blends into the wall, a concealment mirror that can hide valuables, and a smart mattress with pressure relief, temperature controls and a sleep tracker. Elsewhere, there's a library and a games room, as well as a garden with an outdoor theatre and a Robomow robotic lawnmower that cuts the grass at the press of a button. Some people have all the luck!
