110 Tower, Office skyscraper in downtown Fort Lauderdale, US

110 Tower is a 30-story skyscraper with glass and granite facades in downtown Fort Lauderdale. The building rises above Southeast 6th Street adjacent to the Broward County Courthouse complex.

110 Tower was one of the first modern high-rise office buildings constructed in Fort Lauderdale, rising 410.1 feet (125.0 m) and becoming part of the city's skyline. In September 2010 its master tenant AutoNation moved out when its lease expired, leaving the building half empty. Owners Genesis Capital Partners XI, Ltd. then began a $31 million renovation in October 2010, gutting most floors to the slab and replacing electrical, HVAC and water systems; the building earned an Energy Star Rating and LEED EB Gold in 2011.

The building shows the architectural style of late 1980s Florida with modern design elements and functional office spaces that shaped the business landscape of the region.

The building is located near other major structures and is easy to reach from Southeast 6th Street. Visitors should note that the area becomes busier during peak hours.

The blue neon band along the roofline was torn off by Hurricane Wilma's winds in October 2005; the replacement installed in 2010 uses LED lights that can highlight the building's lines in multiple colours.
