Mathias Valon, a French entrepreneur, has lived and worked in Thailand with his family for many years, on Koh Samui.
Before real estate, he built an import-export business between France and Thailand. A property investor for many years, he refined his method purchase after purchase: buy below market, transform, rent, sell with real accounts.
The club only opened once this method had been proven with his own money.

Three pilot houses were bought, transformed and funded with the founder’s own money, without a single dollar from members:

Waterfall 2 HouseBeing transformed: 6 bedrooms, large pool with jacuzzi, outdoor bar and kitchen. Delivery planned for December 2026.
These three houses are not open to members: they are the proof. Members invest in the following operations.
How members are protected
- Each member directly owns their share of the house: a superficies right and a 30-year lease registered in their name at the Land Department, the Thai land registry. The land is held by a Thai land company.
- One dedicated bank account per house; net rent is paid every month.
- The reservation deposit (10% per share) is held in escrow with a licensed agent, and fully refunded if the operation is not 100% funded.
- Priority repayment of members’ capital, written into the agreement.
- No entry fees, no management fees taken from capital.
- A share can be sold before five years, at the negotiated price: first to the house’s members, then to the land company, then to a buyer approved by the club.
