Owners of Capital Gate Tower, Abu Dhabi's leaning glass tower, announced Tuesday that more than 60 percent of the building is now leased. Etihad Rail, which leased 4,000 square meters (43,500 square feet) of the building, will become an anchor tenant along with the existing Hyatt hotel.

“Etihad Rail fits our target occupier market for Capital Gate," Khaled Alsafi Al Hashmi, chief operating officer of the owning company, told Arabian Business.

The agreement is big news in Abu Dhabi, where there is an abundance of empty office space after a surge in building in recent years. Office rental rates have dropped by more than 40 percent in the city since 2008.

The 165-meter high (540-foot) Capital Gate features 35 floors of office space, while the upper floors host the Hyatt Capital Gate, one of the first Hyatt hotels in Abu Dhabi.

This building, completed in 2011, was named the World's Most Leaning Manmade Tower by the Guinness World Record for its 18-degree lean, in June 2010.

Capital Gate was the featured case study in the latest edition of the CTBUH Journal.
