The private inventory of a lifetime.
Some things are never for sale.They still change hands.
The homes that matter, before they reach the market.
Off-market estates across Ibiza, St. Tropez, St. Barths and Gstaad. When a member sells, members hear first. Not listed, not photographed for portals, never discussed in print. In Abu Dhabi, only Saadiyat: positions taken before the renders go public.
The right home finds the right hands.Nothing more is required.
Most works are visited.
A few come home.
The world sees it in a museum, behind the rope, under glass, in a crowd. Then one morning it hangs on a member’s wall, in their own light, and the room is quiet. The greatest works do change hands. Just never in public.
No rope. No glass. No crowd.Just the work, at home.
The dream car. New, or never made again.
Rare cars, private sales, allocation intelligence, storage, logistics, and ownership without noise.
From a poster on a bedroom wall.To the engine turning on.
Five addresses. By design.
We do not franchise.

In their own words.
“I landed on a Sunday morning with our newborn. Everything was taken care of. My pH 9+ water at the villa, full security coordinated with my own team, complete privacy. I didn’t have to think about a single thing. We came back the following summer.”
“I have a concierge, two assistants, and a chief of staff. I still text Maison X first. I once texted them at 6pm from a meeting in London. By 8pm my wife was at a private dinner party with her best friends on a yacht in Formentera with one of the chefs from Sublimotion.”
“I bought my house in St. Tropez through them before it ever hit the market. I closed in 11 days. The same team that arranged the viewing arranged my birthday party in Ibiza. That’s the beauty of it!”
“I only trust Maison X with my property. Their members are the calibre of guest I want in my home.”
