Make a building fit the map in any turn and still touch a road

A wide building that is turned sideways suddenly covers other tiles, hangs over the edge or ends up only touching a road at its corner. Here is how to check a placement properly and how to tell the player which rule they broke.

Why this works

A turned building is the same shape on different cells, so first work out exactly which cells it covers and only then ask the rules about those cells. Asking in a fixed order, most basic reason first, means the player always hears one clear reason a spot is refused.

When not to use it

Wrong for maps that are not made of square cells, such as free placement or hexagons, where covering cells and touching a road mean something else. If buildings never turn or all fill a single cell, a much simpler check is enough.
