Look at Grumpy's setup and the Cross Roads' Rabbitry setup (site was taken offline so use the Wayback Machine for browsing old pages). Cross Roads and Grumpy provided me with most of the info I got for setting up my rabbitry. And then the other Rabbit Talk guys and gals. And purchase a good rabbit production books. Research, read, Youtube, chat here as much as you can before you start. There is even a University that raises rabbits for hot climates and Grumpy (genius Grumpy) tried them and said they are great producers. They have a little less fur and I think slightly longer bodies but have better heat tolerance and are excellent producers with fast growth rates. (I think it's Alabama or Texas, can't remember now). If you can't find them, let me know.
And use 24x36 cages built back-to-back and side-to-side. height should be 16" to 18". Research the nipples properly. Bad nipples can lead to thirsty rabbits and flooded rabbitries (learnt the hard way). Does your water supply contain a lot of scaling? Filter before going to the nipples to avoid grief. Use a PVC cutter, not hacksaw for the PVC pipes. Use great wire (cheap usually cause grief later) .5" x 1 floor, 2" x 1" sides and top, and 2" high strips of .5" x 1" around the mommy cages to prevent loss of babies. You may find floor nest boxes to be best (Crossroads Rabbitry). Dirt floor below the cages is fine for rabbit. Keep the cages at a height that is comfortable for you and is well above the ground so urine smell is kept down (for the rabbits sake, not yours). Try to avoid stacking if you can. Not usually worth it and it seems as if you have the space. Feed them hay, especially the adults, for many different reasons. Just some of the stuff I wish someone had told me before I started but I caught fast when I came here.
