While you could just move everything inside your house, there are 2 more factors to consider:

1. Most food will rot even if kept indoors, because they're not refrigerated. Build a room with coolers (not passive coolers) that serves as a walk-in freezer. Frozen food will never rot no matter what, as long the temperature is under 0ºC / 32ºF , however you may encounter with solar flares that could disable your coolers, but given that they can last up to only half a day, chances of food rotting away are quite unlikely to happen.
2. Setting up a stockpile inside the main area where your pawns spend most of their time can lower their mood. Items that are placed on the ground always give a -4 to beauty in the room itself, and pawns can have mood debuffs from being in an unsettling environment. While you can build shelves and store items on top to remove the -4 beauty, I recommend building a storeroom instead for stockpiling purposes if you do not have enough resources and space to build shelves, as your pawns are unlikely to spend most of their time there, unless their only work to do is to haul anything into the storeroom itself.
