The MIBC needed a transport terminal with commercial areas with a total area of . Dutch company Citer Invest BV decided to invest in plot 11 of the MIBC back in 2003. Using 1,137 hectares, the company planned to build two office towers () and a 4 star hotel with 390 rooms. The transport terminal was to be connected to Sheremetyevo International Airport, Vnukovo International Airport, the Moscow Metro, and ground transportation through the Third Ring Road. Construction of the complex started in 2008 and was planned to be completed in 2011.

In August 2008, the developer agreed with VTB Bank on project lending, but because of the Great Recession, the bank was unable to provide financing. As a result, construction was postponed in the first quarter of 2009. By this time, it was possible to erect only a wall in the ground and a pile foundation. Almost a year later, the company managed to raise $355 million with the help of Belgian financial institutions under the contracts issued by VTB. In November 2009, the developer expected that the complex would open in 2013.

In April 2011, the Russian construction company Hals-Development bought 50% plus one share of the project investor.

On 11 December 2014, the art piece Eye of Sauron was planned to be installed roof of the complex to go along with the Russian premiere of the film The Hobbit: The Battle of the Five Armies. This triggered an angry response by representatives of the Russian Orthodox Church.

The complex finished construction in 2016. In November, it became known that Russian banking company Rosselkhozbank is negotiating the purchase of a 34-story tower with a leasable area of . The transaction value was estimated to be from 11.5 to 12 billion rubles.
