The Scheunenviertel, part of the Spandauer Vorstadt district in Berlin-Mitte, is a trendy neighborhood that is popular with the international fashion industry, mobile phone, electronics, and IT companies, and creative start-ups and is known for its diverse range of restaurants and cultural offerings. At Rosenthaler Strasse 43-45, directly opposite the Art Nouveau ensemble of the Hackesche Höfe, a modern, three-part, new building has been erected using reinforced-concrete construction. It has seven storys above ground, two basement levels, and a gross floor area of 15,000 square meters. It picks up on and complements the surrounding neighborhood's mix of residential, commercial, and office functions.

The varied, detailed façades of the three buildings are a direct reference to the historical parcelling of the building site. In house 44, an Apple megastore opened in December 2021. Each of the three buildings has generous retail spaces in its basement and on its ground floor. Above the commercial units in houses 44 and 45 are offices and one- to three-room apartments of between 40 and 100 square meters. House 43, on the other hand, is entirely offices and commercial spaces. The set-back story on the sixth floor has roof terraces that are separated from one another by frameless glass elements.

The two courtyard-side roof terraces also feature green pergolas. Their different street façades give the ensemble’s three building units the appearance of distinct and disconnected works of architecture. On the other hand, they blend in architecturally with the old and new façades of the adjacent buildings, and their elaborate design and high-quality materials give the entire block a completely new quality and dynamism. House 43, for example, has a vertically oriented façade of grey Kohlplatter shell limestone.

A natural stone from near Kirchheim in Baden-Wuerttemberg, Kohlplatter has distinctive rust-brown marbling. This façade is articulated by supports and semicircular pilaster strips. The floor-to-ceiling windows are fitted with brown, powder-coated steel-bar railings from the second floor upwards. The façade of House 44 is of light-colored, horizontally banded natural stone from Portugal, also vertically structured, but this time using supports alone. The windows, like the windows of house 45, have glass parapets. House 45 stands out from the other two buildings thanks to its façade of light-colored clinker brick.

An additional articulating element is the lintels of light-colored architectural concrete above the windows. The courtyard façades are more discreet, in keeping with the Berlin building tradition, but at the same time of high-quality design. They have a composite thermal insulation system overlaid with a layer of fine-grained plaster. The ground floor and second floor of the courtyard façades are, like the street façades, clad with natural stone in the case of number 43 and facing brick in the case of number 45; number 44 has a plaster socle zone with high-quality profiling. From the second floor upwards, all buildings have felted plaster flaps as window frames.

To absorb rainwater and provide a habitat for a wide variety of insects and birds, all roofs, including waste areas, are greened. A cistern has been installed to reuse rainwater. The landscaped inner courtyard has a 200-square-meter children's playground and numerous parking spaces for bicycles. Parking spaces and technical areas are separated by a privacy screen of Corten steel panels.
