That is a common feature of land trusts / alternative forms of property ownership wherein ownership of land and structure are separate and control of the land is vested in trust governed by a community board or government entity and/or portions of terminal value are returned to the trust. It's more complicated but that's the gist.

An example of this type of arrangement at scale is 'homeownership' in Singapore, the gov't leases homes to households for 99 yr terms but retains ownership of the land.
