I have 710sf, and to be honest, I feel like it's a little too much (ie, some empty space!)
Before I moved in, I thought about where everything would go, based on use, need, like with like. Mostly it works. I think I use my baking supplies more than 'dinner making' supplies, so maybe some reworking of shelves.
As for 'junk' unprocessed paper (unfiled, un acted upon, receipts etc) wait in the stationary/paper shelf (which has the dictionary, atlas, tax envelope etc). Periodically (last night) I sort it all out, file, prune, act upon.
'Junk' stationary/kitchen stuff are nearby each other. Stationary + bracelets & necklaces and extra sunglasses live in a Ikea Fira (http://www.ikeahackers.net/2007/08/more-fira-mini-chest-hacks.html) Everything has a place. Then there's a little saucer in the top cultery drawer for elastic bands and cable ties as they are more 'kitchen' than 'stationary' (though they are only 1-2 metres apart!
Then I store two memory boxes, two suitcases (one holding out of season clothes) in a niche. And some carpet offcuts, for the niche to get redone 'one day'. I like that there's almost no 'junk' place... Helps to be reminded by atad etc to get onto getting things OUT!
