Geometric Landmark
Trianon, Frankfurt
All good things come in threes: The Trianon is a sophisticated interplay of differently sized triangular areas.


The Trianon high-rise in the Westend of Frankfurt presents itself as a mirrored triangular prism, framed at its corners by slim, aluminum-clad triangular prisms. These corner pillars rise 14 meters above the 186-meter-high main body and support, in a floating manner, a steel structure in the shape of an inverted three-sided pyramid on the roof. The floor plan, a central, equilateral triangle, results from the axes of the acute-angled plot. The 47 floors are accessible via 15 elevators.
