This is an interesting add-on that will expand the cellars in your house. It allows you to add more things to the basement. For example, you can now put a furnace in there, as well as some lights.

The only thing you need to know is that the game uses a different API for its add-ons, so it's possible that the map may not work.

Installation

Download the latest version of SMAPI and the content patcher. Then, unzip this mod and drop it into Stardew Valley/Mods.
