The construction of a rabbit farm in terms of time and price depends on the typical project. If you separate rabbits by gender or do not separate them at all, it will be much easier to build a hangar for rabbits, making individual "cameras" for them will be more expensive and longer.

Every rabbit farm needs a room to keep animals. 

As a rule, in addition to the cage where the pets will be housed at night, you need either a paddock for daytime walking, or a door separating the rabbit farm, that the animals did not spontaneously reproduce and do not contact each other.

For the room in which the animals are kept, a stern compartment and a "nesting" place are also required.
