you still have room. theres the front porch, the living room, dining room and one can fit in the bathroom in a pinch. no, you arent crazy or a pack rat yet. you can still move around.
You've got LOADS of room there.. Get a some of REALLY big bike hooks and hang a few more from the ceiling.
It also looks like you've got a rubbermaid trashcan jammed in there with Blaster written on it. Just take that out the kerb on trash day, even more room
