Sixty2 is located within sight of the Rotes Rathaus city hall, the city’s political center, and in one of Berlin’s oldest streets. Behind the house number 62 is a new, prestigious place to work and live.
Sixty2 is one of the top addresses in the capital city thanks to a visionary transformation of existing office space and a new apartment building by renowned Tchoban Voss architects. The large-scale building complex was originally constructed in 1975 and, with its timeless elegance, provides a stylish foundation for its current role as the focal point between Berlin-Mitte and the Mediaspree.
Sixty2 Klosterstrasse 62 is located in the middle of the economic merger of Gendarmenmarkt, Alexanderplatz and the Mediaspree. A perfect symbiosis of all the factors that define Berlin: political center, start-up hub and cultural metropolis.
Klosterstrasse has always played a central role: it is one of the oldest streets in the Berlin-Mitte district. The name goes back to the Graues Kloster, a former Franciscan monastery with a socio-political function. The street is also named after the monastery quarter, where numerous architectural monuments are located – and it is framed by representative buildings such as the Old City Hall, the Parochial Church, as well as the Dutch Embassy. Only a few steps away is the Rolandufer, a promenade with a green strip on the River Spree, which connects Klosterstrasse and Mühlendamm with a walkway.
Alexanderplatz and the Nikolaiviertel can be reached by foot in a few minutes. The Klosterstrasse subway station directly in front of the building is connected to Alexanderplatz, one of the most important Berlin shopping locations and a central hub of the public transportation system.
The existing building was constructed in 1975 and is an example of the change in architectural significance that took place under the term “East Modernism”. The reinforced concrete skeleton made industrial construction in the GDR possible and still characterizes many cityscapes today – it forms the basis of the building. The well-thought-out functionality on the one hand, but also the aesthetics of the clear-cut design, are experiencing a new appreciation and revival today.
Significant highlights in the existing building of Sixty2 are carefully restored: The mosaic on the first floor, the trapezoidal windows, and the listed entrance gates. These remain focal points. The decision to transform rather than demolish extensive parts of the building also has another important benefit: The stored “gray energy” contributes to a positive sustainability balance of the entire project, as construction materials are saved on a large scale.
The West Building is receiving a comprehensive makeover through a renovation and reconstruction of the interior spaces as well as an expansion through a new building. With the extension of the areas into the inner courtyard and the addition of a stacked storey, an area of 7,200 m² is being created for a wide variety of office uses. A lively new courtyard design, sustainable greenery and opening the ground floor to the city center will provide space for culinary concepts and will ensure even more quality of life.
Furthermore, a new residential building is planned in the courtyard, which will offer 2,650 m² of rental living space in the future. The special quality of this apartment building is the central location in Berlin-Mitte with a quiet, green courtyard, which has always been a sought-after residential situation in Berlin. Generous glass fronts and balconies will emphasize the exclusive lifestyle of the apartments.
In a later second construction phase, the renovation and extension of the East Building by a new building is planned. On the one hand, the existing building along Stralauer Strasse and Waisenstrasse will be converted. This will create new, state-of-the-art office spaces. In addition, the existing building will be enlarged by an extension and thus visually enclosed. This will provide additional commercial space as well as a striking architectural design that creates a representative entrance situation on Waisenstrasse.
