The DELTA building is the newest and also the largest addition to the BB Centre complex. It comes from the workshop of the architectural studio Aulík Fišer architects and was completed in 2015. It is located in a place bordered by Vyskočilova and Václava Sedláčka streets. The DELTA building consists of two separate buildings with a very efficient floor plan in the shape of two “H” letters, which can also be connected on each floor by a footbridge. Thanks to it, a unique area of ​​up to 4,530 m2 can be obtained on one floor. There are 880 parking spaces for tenants and the public on five underground floors. There are roof terraces with rich greenery and relaxation zones, a canteen and a restaurant. The western part of the building is lined with a green line with an artificial riverbed, and the newly built Brumlovka Park is connected to the southern side of the building. The DELTA building has excellent transport accessibility: a bus stop (Vyskočilova) directly in front of the building (two stops from the C metro stations Budějovická and Kačerov), direct connection to the Prague ring road and the D1 motorway.
