I've been checking out companies who do aircraft fitouts.
This master bedroom was produced by Lufthansa Technik AG
Greenpoint Technologies is an American company but mainly specialise in Boeings. Nevertheless, their website shows some nice interiors and some good floor plans we could discuss.
This layout for instance includes a master bedroom for Zeke and his own lounge room. A dining room for the entourage and seating for all. Upstairs, rudimentary sleeping accommodation and lounge space for the entourage. It has an office, but lacks a gymnasium.
