Help with housing please.

We are picking up (hopefully) this delightful Bun as a wife for Louis, on Saturday:

Lou currently has a cage which is always open, and his own room to run around in during the day, and then run of the house when we're home from work.

Question is, what is best to do housewise for the little lady? Will she want her own house? I don't want to spend lots of money on a new cage/crate etc for her, for them to both get on great and have the run of the room together.

Any suggestions would be great. Many thanks for your help in advance

Gorgeous bunny. What about a small dog crate if the bunnies are going to be freerange in the room. They have some reasonably priced ones on ebay.
