Sky Office Tower is a dual business tower, elliptically shaped, located in Zagreb, Croatia, north of the Zagrebačka Avenue, near the intersection with Zagrebačka cesta.

This would have made the tower 108 meters high, matching Zagreb Cathedral, the tallest building in the city.

The construction was halted for 6 months in 2009 due to funding problems caused by the ongoing global financial crisis.

[12] Access to the underground garages is provided via two entry-exit ramps, which are heated against freezing.

Underground levels with parking and storage areas are directly linked to the office spaces.
