Upper West
Rising prominently at the intersection of Kurfürstendamm and Breitscheidplatz, Upper West is one of Berlin’s most striking high-rise buildings. Completed in 2017, this architectural marvel redefines the skyline of western Berlin, blending commercial functionality with aesthetic innovation. As a symbol of the city’s post-reunification urban resurgence, Upper West is not only a visual icon but also a technical feat of engineering and sustainable design.
Architectural Vision and Urban Context
Strategic Location
Upper West is situated in the heart of Berlin’s City West, directly opposite the historic Kaiser Wilhelm Memorial Church and adjacent to the iconic Bikini Berlin complex. This location places it at a nexus of commerce, culture, and tourism, making it a focal point for both locals and international visitors.
Design Philosophy
Designed by Christoph Langhof, the building embodies a dynamic interplay of verticality and rhythm. Its white aluminum facade, punctuated by horizontal bands of glazing, creates a wave-like visual effect that contrasts with the more rigid geometries of neighboring structures. The design aims to evoke movement and lightness, despite the building’s substantial mass.
