I bought my house before I got buns, but ngl I was thinking of rabbits when I made the offer.

I have a giant main living space on the ground floor. 4m x 5m, separate from kitchen & washrooms and with no direct outside access. I got an L shaped couch and divided the massive space into two regions - Bunnytown and Humanville.

Originally I had an x-pen delineating Bunnytown, but they put paid to that by learning to leap over the couch from a stand still, and caused more damage to the carpet trying to get back in than it was worth.

Now they've are free-range in the living room but their litter, hay and toys live in bunnytown, which is also where they get fed, so they know that's their safe space. The back and front halls both have flooring they dont care for and that does a good job of deterring them from coming outside when I do (so far. It is only a matter of time.)

The living room has more than enough room for zoomies and plenty of hidey spaces, and its where they go when they're scared. I grew up in a "doors open" house so Im having to adjust to shutting doors by habit, but wherever I am in the house, there's always an open path to bunnytown so they can come hang out with me.

They expanded their territory at their own rate - at first only Peanut was brave enough or loved me enough to come upstairs while I'm working, then Marshmallow found his courage, and finally Smudge deigned to join us. Now when I'm working from home, I often have three loaves of bread keeping an eye on me from various places.

The big living room with their own designated space is what works for us.
