Typically, you keep a rabbit in a kind of enclosure, like a cage, hutch, dog crate, pet exercise pen, or home-made cube condo. Some cages are too small for rabbits - it depends on what kind of rabbit you have, like whether he/she is a dwarf, or just regular size, or a Flemish Giant, etc.
The cube condo (made with NICs, Neat Idea Cubes) is a good option because you build it yourself, so it fits yours, and your bunny's, needs. You can make it as big/small as you want, you can also add levels, or make it some sort of funky shape.

It is generally not recommended to keep a wild rabbit as a pet. Wild rabbits have specific needs and behaviors that can be difficult to meet in a domestic setting. It is better to adopt a domesticated rabbit from a shelter or breeder if you are interested in having a pet rabbit.
