Toys are in her room. When she was smaller, the dolls house was in the bay window and there were some bits in the bottom of the tall cupboard in the lounge (jigsaws, games etc). Used to bring a box of, say, dolls down at the weekend and then pack away again Sunday evening. Sports kit is hanging up in her wardrobe. Her school bags hang on hooks behind the dining room door, along with all our coats and her ice skating bag and swimming bag.
Board games are in one of the cupboards the sideboard in the dining room. The taller cupboard on the other side has 6 pull out cubes. One for hats / scarves, 1 for cycle helmets, 1 for tutoring stuff (her homework sheets come home in her book bag are done and go back), 1 for laptops and chargers, 2 are currently empty 
Her books are on the shelves in the study mainly. It's all novels now - we passed the younger stuff on when she grew out of them, apart from 10 or so special books that held particular memories.
You see the fitted wardrobes? They hide a lot! DD's has all her clothes behind the two doors (rail with drawers under), her dressing up stuff behind the single door. Boxes of toys in the bottom. There's a shelf above with her memory boxes, paperwork, all sorts. We also left the back of the wardrobe section off her bed and that's stuffed with more toys, stacked up on boxes. Usually it's the dolls bedroom!
In the spare room wardrobe there's all our clothes that don't fit hanging up. A 12 man tent, dehumidifier, tonnes of sailing equipment and god knows what else. The top shelf has more stuff including 15 years worth of sailing magazines. The wardrobes are cavernous! Maps in the drawers under the bed. There'll be a 7 foot inflatable dingy coming home soon that usually spends the winter on the spare bed ...
Our wardrobe has our clothes, 4 suitcases (inside one another, 8 washing baskets, bags, shoes, all our paperwork (15 box files along the shelves). Sewing kit is up there too, plus medicines, spare sock basket, all sorts.
I am ruthless at getting rid of "stuff" and love a good clear out, but we do have a lot of things too. The garage isn't used for storage (apart from a few things in the ceiling as it is boarded out). I think only having 1 child probably helps
