The world’s tallest skyscraper has unexpectedly closed to the public a month after its lavish opening, disappointing tourists headed for the observation deck and casting doubt over plans to welcome its first permanent occupants in the coming weeks.

Electrical problems are at least partly to blame for the closure of the Burj Khalifa’s viewing platform – the only part of the half-mile high tower open yet. But a lack of information from the spire’s owner left it unclear whether the rest of the largely empty building – including dozens of elevators meant to whisk visitors to the tower’s more than 160 floors – was affected by the shutdown.

So far only half of the building is truly complete and the total cost was around $1.5 Billion USD. Dubai is having serious money problems and has already told everyone holding debt from Dubai that they will not back any of it.

No one is sure when or if the building will reopen, but the daily cost of just keeping the building operational may make this entire project a loss for many years to come.
