How a family office is built

Five layers, from the ground up.

Every durable family office rests on the same five layers: jurisdiction, purpose, entities, governance and investment policy. Assets create wealth; the structure decides whether it survives.

The ground: Jurisdiction The law each entity answers to, and the political weather it stands in.

How a family office is built, in five layers. On screen text: 1, Jurisdiction, the ground: The law each entity answers to, and the political weather it stands in. 2, Purpose, the foundation: What the wealth is for: values, goals and a family charter. 3, Entities, the columns: Holding companies, trusts and foundations: the boundaries around risk and ownership. 4, Governance, the beam: Who controls what, and how control passes. 5, Investment policy, the roof: How capital is allocated and reported, set down in writing. Assets create wealth. Structures determine whether it survives.

The five layers explained in detail

A reference you return to, not a feed you scroll.

Four ways into the same subject: how sophisticated capital is built, structured, allocated and preserved. Every guide is answered in its first lines and every figure carries its source and year.

Compound interest

What patience does to capital.

100,000 dollars left to compound for 30 years, against the same sum earning simple interest. At 5 percent a year, compounding turns it into 432,194 dollars, against 250,000 with simple interest. Choose a rate: the curve redraws and the gap opens in real time.

Compound interest: value = principal × (1 + rate)^years. Simple interest: value = principal × (1 + rate × years).
