German studio Stephan Braunfels Architekten designed Gifhorn Volksbank, an intriguing modern building in northern Germany. The stone, glass, and metal exterior juts upward, dagger-like, asserting that it is all business here. Or is it? There is a playful aspect to the design as well. By manipulating the angles of gables and glazing, the designers were able to create the optical illusion that both buildings are of the same size and shape from certain angles but not from others. Take a look at these images taken by Olaf Mahlstedt – can you spot the differences as the perspective changes?
