How many bikes is it right to own?

Partner is showing signs of disapproval of me "needing more than one bike". Currently one Fixed being built stored in shed. One geared tourer stored at workshop. One hybrid with child seat and every heavy utility to weigh it down possible. The hybrid is allowed in the house.

2 yr old son has two bikes in the house. One wood, one plastic and is also allowed toys all over the floor in every room and pushchairs, car seats etc everywhere and allowed to throw his dinner at me after I've spent an hour making it.

How to subtly make 2 other bikes appear in the house?

Same here. I'm only allowed the unfinished lo-pro in the kitchen, because I promised I will sell it at some point (for "profit" - yeah, right). There's also my stepson's hybrid in the kitchen ("because it's expensive" and almost ready Fuji Track Pro hanging on the bracket on the wall behind the fridge. Wooden bike and a plastic trike belonging to my 2 y/o always somewhere in the way. A mountain bike in the garden next to a rusty bmx. Folding bike in the boot of my car. The shed is full of spare parts for my other car which needs to be restored at some point (folding soft top, bumper and a pair of new doors). On top of that unfinished Fondriest frame. I need more space. I'm looking for some kind of metal brackets I can fit in the kitchen to hang up all the light frames, so I don't bump into the stuff at night.
