One question

Who really owns Dusit Central Park?

Plain English in. The agents start with filings and registries.

The first layer

Dusit 70 %, Central Pattana 30 %.

The hotel and residences sit in one company, Vimarn Suriya.1 2 3

The second layer

Not one joint venture. Three companies.

The mall and the offices are separate companies, with Central Pattana in control.1 3

What doesn’t match

When sources disagree, you see it.

Two registered addresses on file for Vimarn Suriya. Symphoria marks it instead of picking one.1 5

What nobody mentions

The partner owns part of the owner.

Central Pattana also holds 17.09 % of Dusit. The land is leased from the Crown Property Bureau, renewable to 2086.2 4

Prove it was there

Every finding signed, with its source.

Share it, and the record is anchored to Bitcoin. Anyone can check it without us.
