The mansion "floated" because it used hydraulic pistons drilled into the foundation of the theatre.
The mansion was probably the biggest, and most amazing, set piece I've ever seen. It could levitate up and back, dissapearing into the fly space above or back into the darkness of the rear stage.
When the story shifted to the mansion - it would illuminate and then float diagonally from the rear flys to downstage deck level. When the story moved to outside the mansion - it would float up and back - dissapearing. It did all of this silently, and with actors moving on it unsecured.
For scenes such as the New Years party, the mansion floated up and stopped halfway into the flys while an apartment set glided on underneath with dozens of actors. The audience was able to watch both scenes at once.
For the finale - the mansion glided up again, a large staircase glided downstage and met with the edge of the now levitating mansion. Joe (who had been shot) stumbled down the stairs falling into the pool - an illuminated and tiled Orchestra Pit (GENIOUS!)
Many people thought the set was lowered from the flys via metal cabling when actually it was raised via hydrulic arms. The hydraulics ensured safety, and ease of motion. It also allowed the machinery to be located far below the stage deck - ensuring it's silence.
Of course it was all computer controlled - and it definitely had issues at times. But it was extremely high-tech at the time and one of the first sets to be completely computer controlled.
