These are hotels that a maison has built into a complete visual world, where the materials, the lighting, the art and the dining carry as much of the proposition as the service does. The guest is paying for the name, the design language and the rarity, and usually above the rate of a traditional luxury house.
The sensor is control, not branding. A house is admitted when the maison has shaped the building rather than lent its name to it — when removing the name would leave the architecture unexplained. A licensing arrangement over a conventional hotel is a ground for exclusion, and we publish the ground.
The question is declared, the sensor is published, and the ground travels with the verdict.
