I used to work in a factory that had adopted the Toyota Lean 5S system. It was an eye opener.
Everything was set up so that a total stranger could walk into our factory floor and find what they were looking for in 30s or less. In general, this means everything clearly labelled, and lots of empty space on the shelves so your eye can quickly isolate the thing you're looking for.
Everything I needed for a particular job was all contained in the same spot - preferably without having to turn around or take an extra step to reach a tool. If I'm making coffee at home, I should be able to grab the coffee, sugar, cream, mug etc. without having to turn around or take an extra step. If I'm going jogging, my jogging clothes are kept with my running shoes and my cellphone sleeve. Everything in the same spot.
If you're moving from an apartment to a house, there's going to be some weirdness because you're used to doing everything in 2 rooms. I'm house sitting right now and it feels super weird to get changed in the bedroom, I'm used to changing in front of the TV. So I moved my suitcase to the rec room. Don't be afraid to do something odd, just make sure the furniture in that room can accommodate what you actually use it for, not what's "normal".
