musing on funding to build

This post is sheer voyerism so please take it for what it is. Assuming the tower is to be built, how would a company go about funding it and what would the share price flow on be. I have done some quick spreadsheeting an a few scenarios. First: raise the lot through a rights issue and the assumption of not wanting the number of shares on issue to be to large. I looked at raising of 1:1 and 2:1 shares held. This deliveres a raising at either $2.12 or $1.06. If we factor in a 30% debt facility the rights issue asking prices drops to $1.48 or $0.74. Assuming these numbers become the new base, I would happily have my current holding diluted to that extent.
