The same firm that brought us the Iron Man-inspired watch winder installed three safes weighing 1.7 tonnes hidden underneath the floor of a European home, only rising up on command, sheathed in bulletproof glass. And then there is an apartment in One Hyde Park, the admirably ostentatious luxury complex in London, that’s been fitted with a Buben & Zorweg safe. But because the paranoid owner feared the people installing the safe would find out where he lived, the interior of the lift was entirely covered in cardboard. With clients like these, Buben & Zorweg unfortunately only has mock-ups of “Billionaire-Style” interiors.
