The developer of a Dubai skyscraper set to become the world's tallest building says the rising tower now stands at a "new record height" of 2,257 feet.

Emaar Properties says the skyscraper — known as Burj Dubai — now has "more than 160 stories." Its exterior is almost done and work has started on the interior.

The company's Monday statement gave no other details. The silvery steel-and-glass building's final height is a secret.

Last summer, the developer announced the building surpassed Taiwan's Taipei 101 which has dominated the global skyline at 1,667 feet since 2004.

In the four years of construction, Emaar twice postponed the skyscraper's finish, now slated for September 2009.
