Nothing yet. Not too much we want to change except a couple of decals, but that will be later.

We kept a couple of bus seats as we have little ones and want them to be safe and strapped into the car seats.
We added a counter with a pump sink, fridge, a custom made-by-me full futon that the wife and I use, and bunk beds for the twins. Our other child sleeps in a pack-and-play. We love the storage above for all our stuff.
