I Do NOT Know What The Hell My Minecraft House's Rooms We'll Be Used For HELP!!!

It Has Like 4 Floors And I've Decided Only On The First Floor Being Used To Put Miscellaneous Stuff In And The Second Floor Being Like My Bedroom .The Second And Third Floor Are A Mystery To Me

you could put a room that has a massive kitchen with both a water and mini farms (3-6 slots per plant (sugar cane, carrots, etc)) and/ or put lots of dining sets, to make it almost like a restaurant! or one large and fancy table and chair set
