When upgrading the houses to mansions, it becomes rather jarring when there are a lot of duplicates of the same variety when in sequence, owed to their size and visibility.
Would it be possible to be able to switch the house style with alt (much like with decorations) whilst in the building relocation blueprint? Then be able to place it back in the same spot? There are mansion models that look better on corners and others that form better continuous straights, for example.
A change like would of course help with lower tiers, as similar decorative issues arise with manors also.
