Hi guys and thanks for the compliments!
Ithink maybe it would be helpful if we add here what aNIC Condo is (for all the newbies)! Basically, its made out of these grids (called Neat Idea Cubes) that are made to create simple shelving. They go by many different names, and the most popular places to find them are Costco and Sams (seasonally), Kmart, and Target. They usually run about 15-20 dollars a box (and you will need 2 boxes to build a cage that is of reasonable size with a second floor).
Many people use cable ties (zip ties) to assemble the panels together, or you may do as I did and use the connectors that came with the cubes.You just have to make sure to leave an opening for a front door. Most rabbits will not need aramp for the second level...they can just jump right on up.
Theflooring is made with a product called Coroplast. It is basically plastic carboard andIve heard some people are able to purchase it at stores like Home Depot. My local HD did not carry it, so we called around to local sign storesand were able to find someone locally who supplied it (I paid $10 for a 4ft x 8ft sheet).
Here are some helpful links for those of you thinking of building one (scroll down to ideas and instructions):

The great thing about these cages is that you may combine different ideas and designs to fit the personality of your bun! It was fun to add little hideouts and toys for him in his new cage, and he loves it!
Good Luck!
