Well here are few things you can do. This is just a broad idea on which u can work upon.
1. Decide the geographical location..whether it is apt and a proper reasoning for it. Decide the location from a group of locations and evaluate each on its pros n cons, to decide the final location.
2.Then what accessories and products are available or infact can be kept in the mall and who all can be attracted (as in footfalls in the form of corporates)
3.Deciding the location & items to be kept...nxt thing should be the area of the mall. As is not a retail mall, a little less of area will be required.
4. But i feel the major problemm that arises is whether the mall will have that kind of a footfall like retail malls. And how to increase that (direct, indirect marketing).
