There are no reliable sources that this was a scam or indeed any sources mentioning the building from the time. If this building gained investment on the basis of it being a 480 ft tall building then both the investors are complete idiots and the scam would have been judged as fraud. The investors can't have done any due diligence at all. Why would there be any value to building at that scale at that location. Building a 480 inch building whilst taking investment to build a 480 ft tower would clearly be shown as fraudulent. I suspect this building has a more mundane explanation: a builder trying out some new techniques or a client that wanted a larger building but ran out of funding.
