“Opened in 2014, the area’s first tower, DC Tower I, was never conceived as a single building but as the first component of a two-tower complex.

The story begins in 2002 when WED (Wiener Entwicklungsgesellschaft für den Donauraum AG) launched an international competition for the development of the last sector of the Donau City, an area of incredible potential on the bank of the Danube, at the head of the bridge connecting historic Vienna to new districts. The proposed urban project envisaged the creation of a real gateway to the city, favoring the construction of mixed-use programs.

The two proposed towers form a whole, like the two separate halves of a monolith. Facing the river, they interact with both the historic city and the new Vienne. After four years of construction, the Dc Tower I became the tallest tower in Austria. With a height of 250 meters (220m + antenna), its 60 floors house office space, a hotel and some shops. The undulations of its façade have since become part of the new skyline of the Austrian capital.

The second tower, currently under study, will be smaller, reaching a height of 175 meters and will have 53 floors. In contrast to the first tower, it will house offices up to a height of 100 meters, and above that, some 470 apartments with loggia spaces equipped with windbreaks. Its facade has evolved a lot since the beginning of the studies. First imagined as the twin tower of the first one, its aspect will finally be very different, integrating the diversity of the towers also under construction in the area.”
