The tourguide didn't mince words, and came at FLW pretty hard for scams and philandering. My understanding is that FLW was kind of a grifter. Outside of being famous for just not paying his employees and designers, he was working on the side to put up houses that were explicitly against his contract after being paid huge cash advances by his friend / employer. He also famously hoarded his designers' and sculptors' ideas and claimed them for himself.
There's some fascinating ideas at play in his houses, and the fact that he designed the furniture for the rooms they would go in is fascinating, even though I didn't care much for his style. The concept of 'compression and expansion' came through well, when you'd walk through a somewhat narrow offset corridor before entering a grand room. It definitely had an impact.
That house was basically a prototype for a bunch of random ideas he had, including a stage for his children and his wife's students to perform plays (she was a youth teacher) complete with a giant mural of a djinn iirc was inspired by one thousand and one nights.
It felt like a psychedelic church.
