I converted my garage into a playroom.
I have no toys in the house

And I hardly see the kids lol.

Oh and the door locks from the house side
Actually, I have to keep a spare house key hidden on the bookshelf in the playroom because it does lock from the house side and if the kids close the door and lock it, there is a danger that I would be stuck out there. It is not so bad now DD1 can unlock the door as well as locking it but the others can still only lock the door but can't unlock it.
