The room is designed for The Squealing Mermaid Boathouse lot (which I will upload at the end of this series). If you plan on placing this room in the Boathouse lot, please check for any double windows and/or doors.
I own all of the Stuff, Game and Expansion Packs that are currently available on Origin (04 February 2021)

For this room you will need: Snowy Escape, Discover University, Cats&Dogs, City Living, Get to Work, Get Together, Parenthood, Jungle Adventure, Tiny Living stuff and Cool Kitchen stuff. If you don't have these packs, some items may not show up in your game. Usually it is something small, like in this case some plates, a tiny plant or a dish rack.

I used the cheats bb.moveobjects, bb.showhiddenobjects and debug. Please use at least the bb.moveobjects before placing the lot. Also, it might be wise to use freerealestate on too.
