How to Unlock Bedroom/Upstairs

To unlock the Bedroom/Upstairs, you need to build the Long Ladder at a cost of 12 Assembly Parts (acquired via fishing) and 1,645 wood. You can find the Long Ladder at the very end of your furniture list. The Long Ladder takes 6 hours to finish building and once the Long Ladder has finished building, it will open the Bedroom/Upstairs area.

Opening the Bedroom/Upstairs area will add a new set of furniture that you can build for that section of your house. Cats will only start visiting once you have built the correct combination of furniture items that are required to attract the Bedroom/Upstairs cats.
