If you were starting from scratch, or moving to a new house, where would you put stuff?
I’m mid way through a house extension and have had to empty or move around most of my belongings for one reason or another. Since everything is moving so slowly with lockdowns, I have time to massively declutter and rethink storage. Up to now I’ve been working off the “where would I look for this first” system but now I’m thinking more about “where should this be kept” ... and I’m stumped 
I have lots of storage areas : utility room (soon), under stairs, top of wardrobe, kitchen top cabinets, attic, hot press, bathroom drawers. The problem is that I don’t have a sense of there being different zones or categories, so there can be multiples of the same sort of thing in different places, or things in odd places just because that’s where they’ve always been.
The hallway under the stairs has always been a massively overstuffed coat cupboard, with sports equipment, hobby bags, carpet off cuts, spare tiles, umbrellas, hats, gloves, high viz, shopping bags.... and our hallway is always a mess with coats on the end of the stairs and school bags dumped.
I’m thinking of packing away anything out of season but where should it go? My first thought was the attic but apparently clothes and fabrics shouldn’t be stored there. Maybe the hot press?
What do you keep in your attic? I’m scratching my head over the state of ours. Theoretically anything that ends up in the attic doesn’t really need to be there (but I’m not quite in that head space yet).
Christmas decorations will stay there for the moment. And other seasonal stuff for Halloween, Easter etc. I have some sentimental stuff but again I’m not sure it should be stored in an attic (papers and photos can deteriorate in hot/cold conditions)
I was thinking of moving sentimental stuff - wedding dress, heirloom christening gown and kids art to the top of my wardrobe but that already has my “going out” shoes, bags and accessories. My wardrobe already has to store out of season clothes and current clothes.
I keep our wetsuits under the bed because I can lay them out without folding or hanging so there’s not a lot of extra space there.
There’s all sorts of other things I’m perplexed about - where should batteries live? Shoe polish? Medicines? Stamps?
I know some people are really sensible about these things, but my brain melts a bit trying to figure it out.
Please help me sort out my house! Do you keep certain items together for particular reasons? If you’ve sorted out storage areas or moved house and started from scratch I would love to hear any tips.
