One Forty West is a mixed-use high-rise building in the Westend-Süd district of Frankfurt, Germany.

Built between 2017 and 2020, the tower stands at 145 m (476 ft) tall and is the current 22nd tallest building in Frankfurt.

[3] The 145-meter-high tower houses a total of 187 rental and condominium apartments from the 24th floor onwards, as well as a hotel below in the immediate vicinity of the Frankfurt Trade Fair.

[5] The high-rise project is described as a hybrid tower, combining two distinctive functions of housing apartments in addition to a hotel.

[6] Between 1970 until it's very demolition on February 2, 2014, the 116-meter-high AfE-Turm owned by the Johann Wolfgang Goethe University was located on the property.

In September 2015, Commerz Real acquired part of the site for what would later become One Forty West in a joint venture with the project developer Groß & Partner.
