BuildFreedom

This mod comes in two versions.

Version 1: Buildings can be placed in mid-air. Demolition won’t affect connected structures unless you drag-select them.

Version 2: Full building freedom. It allows building overlapping, and construction in areas normally restricted by the map. Naturally, you can seize castles, expand infinitely up into the sky, and keep decorating open land outside towns with no limits. Almost everything is permitted; only a tiny number of locations will show red placement markers.

Refer to the readme file for details, which includes a usage tutorial. This is the first release and may contain critical bugs. I haven’t had much time to test them yet.

Blueprints created with floating or overlapping building features only work in this modded environment. Vanilla players cannot use these floating or overlapping blueprints; they will fail to place the corresponding structures.

Conveyor Lifters use a different building logic in this game, so they cannot be placed while the mod is enabled.

The current workaround is to switch back to vanilla mode using a single hotkey when placing Conveyor Lifters. Default key is U , and it is fully customizable.

This solution comes with unavoidable tradeoffs: vanilla blueprints cannot be placed floating, and modded blueprints will not work with Conveyor Lifters. I apologize for this limitation.

I originally created this mod for players who build heavily vertically stacked factory layouts. The base game does not include a "replace" button, which makes modifying already constructed production lines quite tedious. This mod allows temporary floating placement to ease that problem. However, a full playthrough with permanent floating construction is likely not feasible.
