Add a subrule to “Zoning Targets”, called “Buildings”:-

Each Block may contain one or more Buildings, tracked in the Auld Anchorage wiki page as symbols (listed in brackets below) in their block’s square.

As a Staff Action, a Councillor who supports a Party which is in Power may remove a Zoning Target from the map and replace it with a Building. Valid Buildings are:-

• Church (†) A block with a Church may not be gerrymandered.
• Nature Reserve (^) A block with a Nature Reserve ceases to support any Party and cannot be made to support a Party.
• Housing (×) For each Housing Building in a block, that block counts as one extra block (identical to itself but lacking all Housing) for the purpose of the “Surveys” rule.
