We are moving (Hopefully SOON), and one of the #1 requirements for the new house is a BIRD ROOM! I have told my Realtor this is probably more important than most of the other items on the list!! In most of the houses, the 'formal' dining room has been the likely space- Right in the middle so the birds are in the 'flow' of things, near the kitchen so food and sink are close, usually plenty of light, and doors to close it off for our (and their) sanity and protection!!!
Of course, redecorating in a 'bird appropriate' manner will have to be done! Easy clean walls, floors, and, yes- Ceilings. My realtor got a kick out of that one
